William Harvey

by Sir D'Arcy Power

The title-page, which is almost illegible, is written in red ink. It runs, “Stat Jove principium, Musae, Jovis omnia plena. Prelectiones Anatomiae Universalis per me Gulielmum Harveium Medicum Londinensem Anatomie et Chirurgie Professorem. Anno Domini 1616. Anno aetatis 37 prelectae Aprili 16, 17, 18. Aristoteles Historia Animalium, lib. i. cap. 16. Hominum partes interiores incertae et incognitae quam ob rem ad caeterorum Animalium partes quarum similes humanae referentes eas contemplare.” The motto prefixed to the title-page that “everything is full of Jove” is an incorrect quotation from the third Eclogue of his favourite author Virgil, of whom he was so enamoured that after reading him for a time he would throw away the book with the exclamation, “He hath a devil.” This particular line appears especially to have struck his fancy, for he quotes it twice in his treatise on development, and he works out the idea which it represents in his fifty-fourth essay. He there shows that he understands it to mean that the finger of God or nature, for with him they are synonymous terms, is manifest in every detail of our structure whether great or small. For he says: “And to none can these attributes be referred save to the Almighty, first cause of all things by whatever this name has been designated—the Divine Mind by Aristotle; the Soul of the Universe by Plato; the Natura Naturans by others; Saturn and Jove by the Gentiles; by ourselves, as is seemly in these days, the Creator and Father of all that is in heaven and earth, on whom all things depend for their being, and at whose will and pleasure all things are and were engendered.” He thus opened his lectures in a broad spirit of religious charity quite foreign to his environment but befitting the position he has been called upon to occupy in the history of science.

These notes of Harvey’s visceral lecture are of especial value to us though they are a mere skeleton of the course—a skeleton which he was accustomed to clothe with facts drawn from his own vast stores of observation, with the theories of all his great predecessors and with the most apposite illustrations. Fortunately they deal with the thorax and its contents so that they show us the exact point which he had reached in connection with his great discovery of the circulation of the blood and the true function of the heart. The notes therefore are interesting reading quite apart from the peculiarities of their style.

Harvey was so good a Latin scholar, and during his stay in Italy had acquired such a perfect colloquial knowledge of the language that it is clear he thought with equal facility in Latin or in English, so that it is immaterial into which language he put his ideas. He uses therefore many abbreviations, and whole sentences are written in a mixture of Latin and English, which always sounds oddly to our unaccustomed ears, and often seems comical. Thus, in speaking of the lungs and their functions, he says, “Soe curst children by eager crying grow black and suffocated non deficiente animali facultate,” and in speaking of the eyes and their uses, he says, “Oculi eodem loco, viz., Nobilissimi supra et ante ad processus eminentes instar capitis in a Lobster ... snayles cornubus tactu pro visu utuntur unde occuli as a Centinell to the Army locis editis anterioribus.” Sometimes he embodies an important experimental observation in this jargon as in the example, “Exempto corde, frogg scipp, eele crawle, dogg Ambulat.”

The more important and original ideas throughout the notes are initialled WH., and this seems to have been Harvey’s constant practice, for it occurs even in the books which he has read and annotated, whilst to other parts of his notes he has appended the sign Δ.

The lectures were partly read and partly oral, and we know from the minute directions laid down by the Barber Surgeons Company the exact manner in which they were given. The “Manual of Anatomy,” published by Alexander Reid in 1634, has a frontispiece showing that the method of lecturing adopted in England was the same as that in use throughout Europe. The body lay upon a table, and as the dissections were done in sight of the audience, the dissecting instruments were close to it. The lecturer, wearing the cap of his doctor’s degree, sate opposite the centre of the table holding in his hand a little wand[2] to indicate the part he mentions, though in many cases the demonstration was made by a second doctor of medicine known as the demonstrator, whilst the lecturer read his remarks. At either end of the table was an assistant—the Masters of the Anatomy—with scalpel in hand ready to expose the different structures, and to clear up any points of difficulty. The audience grouped themselves in the most advantageous positions for seeing and hearing, though in some cases places were assigned to them according to age and rank.

The lecturer upon Anatomy, apart from the fact that he was a Doctor of Physic was a person of considerable importance in the sixteenth century. The greatest care was taken of him, as may be understood from the directions which the Barber Surgeons gave to their Stewards in Anatomy or those members of the Company who were appointed to supervise the arrangements for the lectures. They were ordered “to see and provide that there be every year a mat about the hearth in the Hall that Mr. Doctor be made not to take cold upon his feet, nor other gentlemen that do come and mark the Anatomy to learn knowledge. And further that there be two fine white rods appointed for the Doctor to touch the body where it shall please him; and a wax candle to look into the body, and that there be always for the doctor two aprons to be from the shoulder downwards and two pair of sleeves for his whole arm with tapes, for change for the said Doctor, and not to occupy one Apron and one pair of sleeves every day which is unseemly. And the Masters of the Anatomy that be about the body to have like aprons and sleeves every day both white and clean. That if the Masters of the Anatomy that be about the Doctor do not see these things ordered and that their knives, probes, and other instruments be fair and clean accordingly with Aprons and sleeves, if they do lack any of the said things afore rehearsed he shall forfeit for a fine to the Hall forty shillings.”

The whole business of a public anatomy was conducted with much ceremony, and every detail was regulated by precedent. The exact routine in the Barber Surgeons’ Company is laid down in another series of directions. The clerk or secretary is instructed in his duties in the following words: “So soon as the body is brought in deliver out your tickets which must be first filled up as followeth four sorts:—The first form, to the Surgeons who have served the office of Master you must say: Be pleased to attend &c. with which summons you send another for the Demonstrations: to those below the Chair [i.e., who have not filled the office of Master of the Company] you say: Our Masters desire your Company in your Gown and flat Cap &c. with the like notice for the Demonstrations as you send to the ancient Master Surgeons. To the Barbers, if ancient masters, you say: Be pleased to attend in your Gown only, and if below the Chair, then: Our Masters desire &c. as to the others above, but without the tickets for the demonstrations.

“The body being by the Masters of Anatomy prepared for the lecture (the Beadles having first given the Doctor notice who is to read) and having taken orders from the Master or Upper Warden [of the Company] of the Surgeons’ side concerning the same, you meet the whole Court of Assistance [i.e., the Council] in the Hall Parlour where every gentlemen cloathes himself [i.e., puts on his livery or gown], and then you proceed in form to the Theatre. The Beadles going first, next the Clerk, then the Doctor, and after him the several gentlemen of the Court; and having come therein, the Doctor and the rest of the Company being seated, the Clerk walks up to the Doctor and presents him with a wand and retires without the body of the Court [i.e., the theatre in which the assemblage of the company technically constituted a “court”] until the lecture is over when he then goes up to the Doctor and takes the wand from him with directions when to give notice for the reading in the afternoon which is usually at five precisely, and at one of the clock at noon, which he pronounces with a distinct and audible voice by saying, This Lecture, Gentlemen, will be continued at five of the clock precisely. Having so said he walks out before the Doctor, the rest of the Company following down to the Hall parlour where they all dine, the Doctor pulling off his own robes and putting on the Clerk’s Gown first, which it has always been usual for him to dine in. And after being plentifully regaled they proceed as before until the end of the third day, which being over (the Clerk having first given notice in the forenoon) that the lecture will be continued at five of the clock precisely (at which time the same will be ended) he attends the Doctor in the clothing room where he presents him folded up in a piece of paper the sum of ten pounds, and where afterwards he waits upon the Masters of Anatomy and presents each of them in like manner with the sum of three pounds, which concludes the duty of the Clerk on this account.

“N.B.—The Demonstrator, by order of the Court of Assistants, is allowed to read to his pupils after the public lecture is over for three days and till six of the clock on each day and no longer, after which the remains of the body is decently interred at the expence of the Masters of Anatomy, which usually amounts unto the sum of three pounds seven shillings and fivepence.”

The study of Anatomy seems to have been regarded universally as an exhausting occupation, for throughout Europe it was the custom to present the auditors with wine and spices after each lecture, unless some more substantial refreshment was provided.
