VOL. LVII.] PHILOSOPHICAL TRANSACTIONS. 387 



The next day, having found that the mercury rose 1 Q degrees in 5 minutes, 

 by the heat of his stomach ; and that his pulse beat 77 in a minute, he took gij 

 of camphire in a little of the syrup of pale roses ; immediately after swallowing 

 it, he felt a sensation in his mouth something similar to that occasioned by strong 

 peppermint-water, but much more disagreeable ; 10 minutes after he had taken 

 it he applied the thermometer to his stomach ; in 5 minutes the mercury rose 

 1 8 degrees, which was 1 degree less than it had done before he had taken it. 

 His pulse now beat only 70, whereas before he took the dose it had beat 77 : 

 25 minutes after he had taken it, he applied the thermometer again, and the mer- 

 cury rose the same as at the last trial, but his pulse had increased from 70 to 77, 

 the exact number which it had beat before he took the camphire ; soon after this 

 his head became so very giddy, that it was with great difficulty he could walk 

 through the room. In this condition, he had an inclination to breathe the fresh 

 air, opened the window and looked over into the street, where every thing ap- 

 peared to him in the utmost tumult and confusion ; feeling himself in danger of 

 tumbling from his station, he shut the window and staggered from it to bed, 

 threw himself down upon il, and having a book with him, endeavoured to read, 

 but had no distinct idea of any one sentence, and far less could he connect 2 

 or more of them together, so as to comprehend the meaning of the author : not 

 being able to amuse himself by reading, he rose, to see whether he could walk 

 any better, but, to his great mortification, found that he was more giddy, and 

 could hardly walk at all. He then returned to the bed, and feeling himself 

 thirsty, called for some mutton broth ; it being dinner time, the servant, instead 

 of bringing the broth, covered the table as usual, not knowing that he was any 

 way disordered. Seeing the dinner on the table, he got out of bed again, and 

 with no small reluctance, swallowed down a plate-full of the broth, but could 

 neither taste bread nor meat, on account of a nausea, which however was not 

 accompanied with any inclination to vomit. 



He now staggered again to the bed, and took up the book he had left there, 

 with a design to divert the attention of his mind into some other channel than 

 that into which the confusion of his ideas had hurried him : at this time, self- 

 preservation suggested to him the expediency of taking a vomit ; but as he felt 

 very little pain, and was not apprehensive of much danger, he resolved not to 

 spoil the success of his experiment by evacuating the camphire before he should 

 discover what its effects would be. Hitherto, amid a tumult of indigested ideas, 

 he had retained some degree of sensibility ; but now there arose such a noise in 

 his ears, the confusion and giddiness of his head increased so much, that all con- 

 sciousness of what was present, as well as memory of what was past, were soon 

 entirely obliterated, so that whether he endeavoured to read in the book he had 

 taken up, or what else he did, he knew not.
