Copy of a LETTER from Archbishop LAUD
To the Warden and Fellows of All Souls Coll. Oxford.
Communicated by a Gentleman of C. C. C. Oxon.
Salutem in Chrifto,
HESE are on the behalf of an honest man, and a
good scholar, 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 succeed in his place; now having seriously deliberated with myself touching this business, and being willing to recommend such an one to you, as you might thank me for, I am resolved to pitch upon Mr. JEREMIAH TAYLOUR of whose abilitys and fufficiencys every ways I have receiv'd very good assu
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 society. 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 University College. Neither can I learn that . there is any thing in your local statutes against it; I doubt not but you will use him with fo fair respects, as befits a man of his rank and learning, for which I shall give you thanks. So I leave him to your kindness, and rest
Your loving friend
An extract of a Thesis read before Mr. HALLER,
In October 1749. By Mr. F. G. ZINN.
E X PER I M E N T 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 instrument through the mass of the brain, in such a manner, that it was fixed strongly in the bone of the basis of the skull. After the stroke was given, the dog seem'd as unaffected, as if no-hing at all had happen'd; and continued brisk and sensible, to every thing that was done to exasperate him; he heid up his head and look'd about him, and there was nothing particular but a little faver, which fell from his mouth. Some time after he fell fast alleep, and I endeavour'd to rouze him, by making a noise, to no purpose; for he immediately fiept ‘again : I then perceived that the muscles of the right side were ítruck with the palsy. I left him in this condition, at eleven o'clock. Returning at four, I still found him in the same condition : but the desire I had to change the scene, caused me to withdraw the instrument. All of a sudden the face of affairs was changed: the dog began to groan, to whine and vomit: the muscles on the right side continued quite paralytick, without motion or fceling: the sleepiness was now more strong, for we could indeed wake him, by strong irritation, but then he was more stupid, and fell asleep immediately again: at the same time his pulse was feverish: I return’d to see the dog at seven, and found no alteration, but the next day he died. I immediately open'd the skull, and found the longitudinal sinus had been penetrated. The inftrument, after wounding the anterior part of the corpus callosum, 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 skull, in the bone of which the instrument was fixed,
EXPERIMENT II. I thrust the fame instrument 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 so lively as to listen to the barking of another dog in the neigbourhood. Returning the next day, at one in the afternoon, I found him safe and sound, brisk and in no wise apoplectick; and I even perceiv'd that he had struggled very much, in order to get loose. This was on Sunday, wherefore considering that his howling might incommode the neighbourhood, he was immediately killed. After opening the brain, I found the instrument had pass’d through the middle of the corpus callosum, and had penetrated the thalamus of the optick nerves, in the place where they meet in the anterior and superior ventricles.
E X PER I M E N T III. Being afraid that the apoplexy, caused by the effusion of the blood of the finus, should hurt the experiment, I again thrust the instrument into the right side of the head of a dog, from the right to the left. The dog lived twenty two hours, constantly lively and brisk, without being paralytick,
any part of the body, except in the last 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 instrument, after having past through the middle of the corpus callosum, 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.
EXPERIMENT IV. At seven in the evening, I thrust the same instrument into the head of a young dog, from the right to the left. At first he seem'd a little stunn'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 one side, but more brisk and lively than the evening before. But being obliged to go a journey, I killed him at noon ; and opening the cavities of the breast, by a large wound on each side, he continued to live a quarter of an hour longer. The next day I open'd the skull, and found the corpus callosum 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 thrust the instrument from the right to the left, and then from the left to the right. After the first stroke, I unloosed 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 senses and motions. Willing to make other experiments on this animal, I thrust the instrument thro’ the nape of the neck, into the medulla spinalis of the back, between the first vertebra and the last 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 moticn and sensation. On opening the skull, I found the corpus callosum was penetrated in two places, in such a manner that almost all the anterior part was lacerated. The stroke from the left to the right was turned a little backward, and had passed thro' the pes hippocampi of the right side ; the other stroke from the right to the left had passed through the left thalamus of the optick nerves, and both had penetrated as far as the skull. There was a great deal of blood spilt, in the three anterior ventricles. I found the third stroke had passed through the middle of the medulla spinalis.
EXPERIMENT VI. After having divided the skull of a living dog, but apoplećtick on account of the blood which was' fhed in the
Brain, with a faw, I cut away the brain by slices, as far as the corpus callosum, then slit the corpus callosum, and open’d the ventricles. The creature, who had been quiet while the teeth of the saw had lacerated the dura mater, began to make a noise and to struggle when the medulla was disturb’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 respiration, continued for some minutes. I likewise 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.
EXPERIMENT VII. 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 observed in all these experiments, that the dogs discover'd signs of extreme pain, by crying and howling, while the instrument past through the medulla of the brain.
EXPERIMENT VIII. Another day, I thrust the instrument into the head of a dog of middle size, through the inferior part of the right side, of the hind bone, in almost an horizontal direction, 'till it remained fixed in the opposite bone. The dog was at first 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 brisk 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 instrument, and plung’d it a little higher, through the middle of the bone of the hind part of the head. At this stroke he fell down apoplectick. When I return'd the next day, I found him dead. I open’d the skull, took out the brain,
