Kindly send me proofs as you go on. I want much to see them.

Wright’s collections in North Pacific Expedition are here, and he is turning over his Behring Straits collection and trying to work it out, with some help from me. There is a Hongkong collection; there may be some of these he would like to ask you to name, so far as you may off hand. The Japan collection I will elaborate myself. There is not so much from the north as I expected. They had no chance to explore the small islands connecting with the Kurile Islands. I have only peeped into one or two parcels; but in one I saw two things which will interest you as much as they did me. Imagine the two most characteristic possible eastern United States plants, Caulophyllum and Diphylleia, both, I believe, our very species. Tell this to Dr. Hooker!

The only domestic news I have to tell you is, that on a hot August day our beloved Newfoundland dog was found dead,—really a sad loss. To console us my brother-in-law, a fortnight after, sent me a puppy of the same breed, an uneasy, frolicsome, awkward fellow yet, but promising to be intelligent and very handsome. We could not bear to give him the name of his lamented predecessor; so Mrs. Gray named him Hans,—a souvenir of Pontrilas....

Dr. Gray’s dogs and cats were always well-recognized members of the family. He had a great love of animals, which was warmly returned by his different pets. In his early married life the kittens he helped raise by feeding them with a dropping-tube from his microscope rather preferred him to their young and careless mother, and, confounding all other men with him, were perpetually scrambling into laps, to the surprise of callers. Two grew into fine cats, who demanded a regular attention and consideration from him, reminding him by gentle taps, one on each side, when bedtime came.

Of his first dog, he always said that they stood more in the relation of brothers than master and dog; and the dog felt a guardian care of him. The different characters of his two Newfoundland dogs, and of the smaller ones he had later, interested him, for they were singularly different, though both the Newfoundlands shared his affection for a pretty Maltese cat who had succeeded the other cats; they were especially fond of her kittens and attentive to them, allowing them all sorts of liberties. The cats and dogs always lived affectionately together. Dr. Gray always recognized their good consciences, which varied somewhat with the different type of animal, and considered that the size of different breeds had much to do with their characteristics. They always learned to eat what their master did; not so much, he would say, from any preference for oysters and dry toast, as that they were ambitious to do as far as possible what he did.

He was very skillful in the handling of animals, and they recognized it in allowing him to perform small surgical operations, to dress wounds, etc., with a touching trust and submission.

TO GEORGE BENTHAM.

March 9, 1858.

My dear Bentham,—Many thanks for yours of February 14. Although much pleased to hear from you, I cannot expect to hear often, unless you have something special to say. No one but Hooker can write long and frequent letters while he is doing such a vast amount of work, and keeping up such a fresh, and keen, and scrutinizing interest in such a great variety of subjects. I wonder how he does it. How well oiled the machinery of his brain must be to do it all without great wear and tear! If you or I had half these matters to think of at once, we should go distracted. Warn Hooker to take good care of himself and not break down in health. It is a facility which he inherits, that of turning from one thing to another without loss of time or of working power.

I shall be pleased to see the “Handbook” when it is out. Never mind what people say. I dare say the little book will do a great deal of good....
