[This was Arthur Coga, who had studied at Cambridge, and was said to
be a bachelor of divinity. He was indigent, and "looked upon as a
very freakish and extravagant man." Dr. King, in a letter to the
Hon. Robert Boyle, remarks "that Mr. Coga was about thirty-two
years of age; that he spoke Latin well, when he was in company,
which he liked, but that his brain was sometimes a little too warm."
The experiment was performed on November 23rd, 1667, by Dr. King, at
Arundel House, in the presence of many spectators of quality, and
four or five physicians. Coga wrote a description of his own case
in Latin, and when asked why he had not the blood of some other
creature, instead of that of a sheep, transfused into him, answered,
"Sanguis ovis symbolicam quandam facultatem habet cum sanguine
Christi, quia Christus est agnus Dei" (Birch's "History of the Royal
Society," vol. ii., pp. 214-16). Coga was the first person in
England to be experimented upon; previous experiments were made by
the transfusion of the blood of one dog into another. See November
14th, 1666 (vol. vi., p. 64).]

They purpose to let in about twelve ounces; which, they compute, is what will be let in in a minute's time by a watch. They differ in the opinion they have of the effects of it; some think it may have a good effect upon him as a frantic man by cooling his blood, others that it will not have any effect at all. But the man is a healthy man, and by this means will be able to give an account what alteration, if any, he do find in himself, and so may be usefull. On this occasion, Dr. Whistler told a pretty story related by Muffet, a good author, of Dr. Caius, that built Keys College; that, being very old, and living only at that time upon woman's milk, he, while he fed upon the milk of an angry, fretful woman, was so himself; and then, being advised to take it of a good-natured, patient woman, he did become so, beyond the common temper of his age. Thus much nutriment, they observed, might do. Their discourse was very fine; and if I should be put out of my office, I do take great content in the liberty I shall be at of frequenting these gentlemen's company. Broke up thence and home, and there to my wife in her chamber, who is not well (of those), and there she tells me great stories of the gossiping women of the parish—what this, and what that woman was; and, among the rest, how Mrs. Hollworthy is the veriest confident bragging gossip of them all, which I should not have believed; but that Sir R. Brookes, her partner, was mighty civil to her, and taken with her, and what not. My eyes being bad I spent the evening with her in her chamber talking and inventing a cypher to put on a piece of plate, which I must give, better than ordinary, to the Parson's child, and so to bed, and through my wife's illness had a bad night of it, and she a worse, poor wretch!

22nd. Up betimes, and drinking my morning draught of strong water with Betty Michell, I had not opportunity para baiser la, I by water to White Hall, and there met Creed, and thence with him to Westminster Hall, where we talked long together of news, and there met with Cooling, my Lord Chamberlain's Secretary, and from him learn the truth of all I heard last night; and understand further, that this stiffness of the Lords is in no manner of kindness to my Lord Chancellor, for he neither hath, nor do, nor for the future likely can oblige any of them, but rather the contrary; but that they do fear what the consequence may be to themselves, should they yield in his case, as many of them have reason. And more, he shewed me how this is rather to the wrong and prejudice of my Lord Chancellor; for that it is better for him to come to be tried before the Lords, where he can have right and make interest, than, when the Parliament is up, be committed by the King, and tried by a Court on purpose made by the King, of what Lords the King pleases, who have a mind to have his head. So that my Lord [Cornbury] himself, his son, he tells me, hath moved, that if they have Treason against my Lord of Clarendon, that they would specify it and send it up to the Lords, that he might come to his trial; so full of intrigues this business is! Having now a mind to go on and to be rid of Creed, I could not, but was forced to carry him with me to the Excise Office, and thence to the Temple, and there walked a good while in the Temple church, observing the plainness of Selden's tomb, and how much better one of his executors hath, who is buried by him, and there I parted with him and took coach and home, where to dinner.

23rd. Up, and to the office, where all the morning, and at noon home to dinner, and all the afternoon also busy till late preparing things to fortify myself and fellows against the Parliament; and particularly myself against what I fear is thought, that I have suppressed the Order of the Board by which the discharging the great ships off at Chatham by tickets was directed; whereas, indeed, there was no such Order. So home at night to supper and to bed.

24th (Lord's day). In my chamber all the morning (having lain long in bed) till Mr. Shepley come to dine with me, and there being to return to Hinchinbroke speedily, I did give him as good account how matters go here as I could. After dinner, he being gone, I to the office, and there for want of other of my clerks, sent to Mr. Gibbs, whom I never used till now, for the writing over of my little pocket Contract-book; and there I laboured till nine at night with him, in drawing up the history of all that hath passed concerning tickets, in order to the laying the whole, and clearing myself and Office, before Sir R. Brookes; and in this I took great pains, and then sent him away, and proceeded, and had W. Hewer come to me, and he and I till past twelve at night in the Office, and he, which was a good service, did so inform me in the consequences of my writing this report, and that what I said would not hold water, in denying this Board to have ever ordered the discharging out of the service whole ships by ticket, that I did alter my whole counsel, and fall to arme myself with good reasons to justify the Office in so doing, which hath been but rare, and having done this, I went, with great quiet in my mind, home, though vexed that so honest a business should bring me so much trouble; but mightily was pleased to find myself put out of my former design; and so, after supper, to bed.

25th. Up, and all the morning finishing my letter to Sir Robert Brookes, which I did with great content, and yet at noon when I come home to dinner I read it over again after it was sealed and delivered to the messenger, and read it to my clerks who dined with me, and there I did resolve upon some alteration, and caused it to be new writ, and so to the office after dinner, and there all the afternoon mighty busy, and at night did take coach thinking to have gone to Westminster, but it was mighty dark and foul, and my business not great, only to keep my eyes from reading by candle, being weary, but being gone part of my way I turned back, and so home, and there to read, and my wife to read to me out of Sir Robert Cotton's book about warr, which is very fine, showing how the Kings of England have raised money by the people heretofore upon the people, and how they have played upon the kings also. So after supper I to bed. This morning Sir W. Pen tells me that the House was very hot on Saturday last upon the business of liberty of speech in the House, and damned the vote in the beginning of the Long Parliament against it; I so that he fears that there may be some bad thing which they have a mind to broach, which they dare not do without more security than they now have. God keep us, for things look mighty ill!

26th. Up, all the morning at the office, and then home to dinner, where dined Mr. Clerke, solicitor, with me, to discourse about my Tangier accounts, which I would fain make up, but I have not time. After dinner, by coach as far as the Temple, and there saw a new book, in folio, of all that suffered for the King in the late times, which I will buy, it seems well writ, and then back to the Old Exchange, and there at my goldsmith's bought a basin for my wife to give the Parson's child, to which the other day she was godmother. It cost me; L10 14s. besides graving, which I do with the cypher of the name, Daniel Mills, and so home to the office, and then home to supper and hear my wife read, and then to bed. This afternoon, after dinner, come to me Mr. Warren, and there did tell me that he come to pay his debt to me for the kindness I did him in getting his last ship out, which I must also remember was a service to the King, though I did not tell him so, as appeared by my advising with the board, and there writing to Sir W. Coventry to get the pass for the ship to go for it to Genoa. Now that which he had promised me for the courtesy was I take it 100 pieces or more, I think more, and also for the former courtesy I had done for the getting of his first ship out for this hemp he did promise me a consideration upon the return of the goods, but I never did to this day demand any thing of him, only about a month ago he told me that now his ship was come, and he would come out of my debt, but told me that whereas he did expect to have had some profit by the voyage, it had proved of loss to him, by the loss of some ships, or some accidents, I know not what, and so that he was not able to do what he intended, but told me that he would present me with sixty pieces in gold. I told him I would demand nothing of his promises, though they were much greater, nor would have thus much, but if he could afford to give me but fifty pieces, it should suffice me. So now he brought something in a paper, which since proves to be fifty pieces. But before I would take them I told him that I did not insist on anything, and therefore prayed him to consult his ability before he did part with them: and so I refused them once or twice till he did the third time offer them, and then I took them, he saying that he would present me with as many more if I would undertake to get him L500 paid on his bills. I told him I would by no means have any promise of the kind, nor would have any kindness from him for any such service, but that I should do my utmost for nothing to do him that justice, and would endeavour to do what I could for him, and so we parted, he owning himself mightily engaged to me for my kind usage of him in accepting of so small a matter in satisfaction of all that he owed me; which I enter at large for my justification if anything of this should be hereafter enquired after. This evening also comes to me to my closet at the Office Sir John Chichly, of his own accord, to tell me what he shall answer to the Committee, when, as he expects, he shall be examined about my Lord Sandwich; which is so little as will not hurt my Lord at all, I know. He do profess great generousness towards my Lord, and that this jealousy of my Lord's of him is without ground, but do mightily inveigh against Sir Roger Cuttance, and would never have my Lord to carry him to sea again, as being a man that hath done my Lord more hurt than ever he can repair by his ill advice, and disobliging every body. He will by no means seem to crouch to my Lord, but says that he hath as good blood in his veins as any man, though not so good a title, but that he will do nothing to wrong or prejudice my Lord, and I hope he will not, nor I believe can; but he tells me that Sir E. Spragg and Utber are the men that have done my Lord the most wrong, and did bespatter him the most at Oxford, and that my Lord was misled to believe that all that was there said was his, which indeed it was not, and says that he did at that time complain to his father of this his misfortune. This I confess is strange to me touching these two men, but yet it may well enough as the world goes, though I wonder I confess at the latter of the two, who always professes great love to my Lord. Sir Roger Cuttance was with me in the morning, and there gives me an account so clear about Bergen and the other business against my Lord, as I do not see what can be laid to my Lord in either, and tells me that Pen, however he now dissembles it, did on the quarter deck of my Lord's ship, after he come on board, when my Lord did fire a gun for the ships to leave pursuing the enemy, Pen did say, before a great many, several times, that his heart did leap in his belly for joy when he heard the gun, and that it was the best thing that could be done for securing the fleet. He tells me also that Pen was the first that did move and persuade my Lord to the breaking bulke, as a thing that was now the time to do right to the commanders of the great ships, who had no opportunity of getting anything by prizes, now his Lordship might distribute to everyone something, and he himself did write down before my Lord the proportions for each man. This I am glad of, though it may be this dissembling fellow may, twenty to one, deny it.

27th. Up, and all the morning at my Lord Bruncker's lodgings with Sir J. Minnes and [Sir] W. Pen about Sir W. Warren's accounts, wherein I do not see that they are ever very likely to come to an understanding of them, as Sir J. Minnes hath not yet handled them. Here till noon, and then home to dinner, where Mr. Pierce comes to me, and there, in general, tells me how the King is now fallen in and become a slave to the Duke of Buckingham, led by none but him, whom he, Mr. Pierce, swears he knows do hate the very person of the King, and would, as well as will, certainly ruin him. He do say, and I think with right, that the King do in this do the most ungrateful part of a master to a servant that ever was done, in this carriage of his to my Lord Chancellor: that, it may be, the Chancellor may have faults, but none such as these they speak of; that he do now really fear that all is going to ruin, for he says he hears that Sir W. Coventry hath been, just before his sickness, with the Duke of York, to ask his forgiveness and peace for what he had done; for that he never could foresee that what he meant so well, in the councilling to lay by the Chancellor, should come to this. As soon as dined, I with my boy Tom to my bookbinder's, where all the afternoon long till 8 or 9 at night seeing him binding up two or three collections of letters and papers that I had of him, but above all things my little abstract pocket book of contracts, which he will do very neatly. Then home to read, sup, and to bed.

28th. Up, and at the office all this morning, and then home to dinner, and then by coach sent my wife to the King's playhouse, and I to White Hall, there intending, with Lord Bruncker, Sir J. Minnes, and Sir T. Harvy to have seen the Duke of York, whom it seems the King and Queen have visited, and so we may now well go to see him. But there was nobody could speak with him, and so we parted, leaving a note in Mr. Wren's chamber that we had been there, he being at the free conference of the two Houses about this great business of my Lord Chancellor's, at which they were at this hour, three in the afternoon, and there they say my Lord Anglesey do his part admirablyably, and each of us taking a copy of the Guinny Company's defence to a petition against them to the Parliament the other day. So I away to the King's playhouse, and there sat by my wife, and saw "The Mistaken Beauty," which I never, I think, saw before, though an old play; and there is much in it that I like, though the name is but improper to it—at least, that name, it being also called "The Lyer," which is proper enough. Here I met with Sir. Richard Browne, who wondered to find me there, telling the that I am a man of so much business, which character, I thank God, I have ever got, and have for a long time had and deserved, and yet am now come to be censured in common with the office for a man of negligence. Thence home and to the office to my letters, and then home to supper and to bed.

29th. Waked about seven o'clock this morning with a noise I supposed I heard, near our chamber, of knocking, which, by and by, increased: and I, more awake, could, distinguish it better. I then waked my wife, and both of us wondered at it, and lay so a great while, while that increased, and at last heard it plainer, knocking, as if it were breaking down a window for people to get out; and then removing of stools and chairs; and plainly, by and by, going up and down our stairs. We lay, both of us, afeard; yet I would have rose, but my wife would not let me. Besides, I could not do it without making noise; and we did both conclude that thieves were in the house, but wondered what our people did, whom we thought either killed, or afeard, as we were. Thus we lay till the clock struck eight, and high day. At last, I removed my gown and slippers safely to the other side of the bed over my wife: and there safely rose, and put on my gown and breeches, and then, with a firebrand in my hand, safely opened the door, and saw nor heard any thing. Then (with fear, I confess) went to the maid's chamber-door, and all quiet and safe. Called Jane up, and went down safely, and opened my chamber door, where all well. Then more freely about, and to the kitchen, where the cook-maid up, and all safe. So up again, and when Jane come, and we demanded whether she heard no noise, she said, "yes, and was afeard," but rose with the other maid, and found nothing; but heard a noise in the great stack of chimnies that goes from Sir J. Minnes through our house; and so we sent, and their chimnies have been swept this morning, and the noise was that, and nothing else. It is one of the most extraordinary accidents in my life, and gives ground to think of Don Quixote's adventures how people may be surprised, and the more from an accident last night, that our young gibb-cat
