cine had taken effect, they left him; but, soon after they were gone, he waked; 

 and next day seeming very little, if at all, better, was removed to a private mad- 

 house. There nothing else was done to him; but at night he slept tolerably 

 well, appeared much better next day, and continued mending, till he was in a 

 little time quite well, as he is now. How much of this cure may be attributed 

 to the medicine he did not know, as it did not operate immediately, nor in the 

 usual manner. He mentioned it chiefly to show, that even 20 grs. of musk had 

 no bad effect on him, if they had not a good one. 



Case x. — Not long after, Mr. Louttit and he gave the same dose to a gentle- 

 woman, whose brain had long been turned by religious terrors, which first affected 

 her about the time that her menses ceased. He was at first surprised to find her 

 suddenly become quite gentle, obliging, and reasonable; but these good effects, 

 as she slept but little, went off next day, and she soon appeared neither better 

 nor worse than she was before ; and in the same condition she still continues ; so 

 that neither in this case did the large dose of musk do any mischief. 



Mr. Reid adds, that where he thought the case required it, he had given as 

 far as 24 grs. of musk to convicts, and never found any ill effects from it, 

 though, on some occasions, it disappointed his hopes. Whether there was any 

 error in altering the Tonquinese proportions, the cause of which he cannot 

 recollect, or whether the medicine would have succeeded in the instances where 

 it miscarried, had the original prescription been kept to, and repeated as directed, 

 he leaves to others to judge. Mr. R. concludes with asking, whether the virtues 

 of musk may not be applicable to many other cases, and particularly to the epi- 

 lepsy and the plague.
