Salutem in Chrifto,

HESE are on the behalf of an honeft man, and a good fcholar, Mr. OSBORN being to give over his fellowship was with me at Lambeth, and, I thank him, freely proffer'd me the nomination of a scholar to fucceed in his place; now having seriously deliberated with myself touching this bufinefs, and being willing to recommend fuch an one to you, as you might thank me for, I am refolved to pitch upon Mr. JEREMIAH TAYLOUR of whofe abilitys and fufficiencys every ways I have receiv'd very good affurance. And I do hereby heartily pray you to give him all furtherance by yourself and the fellows at the next election, not doubting but that he will approve himself a worthy and learned member of your fociety. And tho' he has had his breeding for the most part in the other university, yet I hope that shall be no prejudice to him, in regard that he is incorporated into Oxford (ut fit eodem ordine, gradu, &c.) and admitted into Univerfity College. Neither can I learn that . there is any thing in your local statutes against it; I doubt not but you will ufe him with fo fair refpects, as befits a man of his rank and learning, for which I fhall give you thanks. So I leave him to your kindness, and reft

EXPERIMENT

I

FTER having adjusted the trochart to the fore part of the head, of a middle fiz'd dog, over the longitudinal finus, I plunged the inftrument through the mass of the brain, in such a manner, that it was fixed ftrongly in the bone of the bafis of the fkull. After the stroke was given, the dog feem'd as unaffected, as if nothing at all had happen'd; and continued brifk and fenfible, to every thing that was done to exafperate him; he heid up his head and look'd about him, and there was nothing particular but a little flaver, which fell from his mouth. Some time after he fell faft afleep, and I endeavour'd to rouze him, by making a noife, to no purpofe; for he immediately flept again: I then perceived that the mufcles of the right fide were struck with the palfy. I left him in this condition, at eleven o'clock. Returning at four, I ftill found him in the fame condition: but the defire I had to change the scene, caufed me to withdraw the inftrument. All of a fudden the face of affairs was changed: the dog began to groan, to whine and vomit: the mufcles on the right fide continued quite paralytick, without motion or feeling: the fleepiness was now more ftrong, for we could indeed wake him, by strong irritation, but then he was more stupid, and fell asleep immediately again: at the fame time his pulfe was feverish: I return'd to fee the dog at feven, and found no alteration, but the next day he died. I immediately open'd the skull, and found the longitudinal finus had been penetrated. The inftrument, after wounding the anterior part of the corpus callofum, paft towards the hind part, and a litle to the left, thro' the left ventricle, and thro' the left corpora ftriata, as far as the basis of the fkull, in the bone of which the inftrument was fixed.

EXPERIMENT II.

I thruft the fame inftrument through the head of a pretty large dog, a little farther back, over the longitudinal finus, and I left it in the wound. The dog, wounded as he was, was fo lively as to liften to the barking of another dog in the neigbourhood. Returning the next day, at one in the afternoon, I found him fafe and found, brifk and in no wife apoplectick; and I even perceiv'd that he had struggled very much, in order to get loose. This was on Surday, wherefore confidering that his howling might incommode the neighbourhood, he was immediately killed. After opening the brain, I found the inftrument had pafs'd through the middle of the corpus callofum, and had penetrated the thalamus of the optick nerves, in the place where they meet in the anterior and superior ventricles.

The dog lived twenty two

Being afraid that the apoplexy, caused by the effufion of the blood of the finus, fhould hurt the experiment, I again thruft the inftrument into the right fide of the head of a dog, from the right to the left. hours, conftantly lively and brisk, without being paralytick, in any part of the body, except in the laft hours of his life, when the heat and pain had made him feeble: I perceived he might have lived fome days longer, but being impatient, I hanged him. Then opening his head, I perceived the inftrument, after having paft through the middle of the corpus callofum, was fixed in the bone of the skull, on the left of the union of the optick nerves, or at the basis of the skull.

IV.

EXPERIMENT At feven in the evening, I thruft the fame inftrument into the head of a young dog, from the right to the left. At first he feem'd a little ftunn'd, but came to himself, some hours afterwards, and the neighbours heard him bark all the night, The next day I found him indeed paralytick

on

on one fide, but more brifk and lively than the evening before. But being obliged to go a journey, I killed him at noon; and opening the cavities of the breaft, by a large wound on each fide, he continued to live a quarter of an hour longer. The next day I open'd the skull, and found the corpus callofum had been penetrated, ae well as the thalamus of the optick nerves.

EXPERIMENT V.

Being curious to know what would happen, if the corpus callofum was wounded twice, I thruft the inftrument from the right to the left, and then from the left to the right. After the first stroke, I unloofed the dog, who began to walk as if nothing had ailed him; nor did he seem to be more in pain after the second stroke than the first. I went to see him the next day, and found him more feeble, but with all his fenfes and motions. Willing to make other experiments on this animal, I thrust the inftrument thro' the nape of the neck, into the medulla spinalis of the back, between the first vertebra and the laft of the head. This wound caused a great effufion of blood: he lived another half hour, in a very languishing condition, it must be owned, but with some remains of motion and fenfation. On opening the skull, I found the corpus callofum was penetrated in two places, in fuch a manner that almost all the anterior part was lacerated. The ftroke from the left to the right was turned a little backward, and had paffed thro' the pes hippocampi of the right fide; the other ftroke from the right to the left had paffed through the left thalamus of the optick nerves, and both had penetrated as far as the fkull. There was a great deal of blood spilt, in the three anterior ventricles. I found the third ftroke had paffed through the middle of the medulla spinalis.

brain, with a faw, I cut away the brain by flices, as far as the corpus callofum, then flit the corpus callofum, and open'd the ventricles. The creature, who had been quiet while the teeth of the faw had lacerated the dura mater, began to make a noise and to ftruggle when the medulla was difturb'd. After having taken out the medulla oblongata, I then took out all the brain. Immediately the members began to tremble, and the motion of the heart, attended with a deep refpiration, continued for some minutes. I likewife took out the cerebellum, and thrust a probe into the medulla spinalis of the back; hereupon the members fell into convulfions, and the deeper I thrust the point, the more the hind parts were in agitation.

A pigeon being depriv'd of its brain, but having the cerebellum intire, cou'd stand upon its legs, and swallow the food which had been put into its bill.

I obferved in all thefe experiments, that the dogs difcover'd figns of extreme pain, by crying and howling, while the inftrument paft through the medulla of the brain.

EXPERIMENT VIII.

Another day, I thrust the inftrument into the head of a dog of middle fize, through the inferior part of the right fide, of the hind bone, in almost an horizontal direction, 'till it remained fixed in the oppofite bone. The dog was at firft a little ftunned, but came to himself by little andlittle, with great howling. This was done at fix in the evening. Returning to fee him the next day, at one in the afternoon, I found him brifk and lively, and the neighbours told me, that he had bark'd very much all the night. When I perceiv'd this wound had not much affected him, I withdrew the inftrument, and plung'd it a little higher, through the middle of the bone of the hind part of the head. At this ftroke he fell down apoplectick. When I return'd the next day, I found him dead. I open'd the skull, took out the brain,
