XYI. — On the Musculae Anatomy of the Rhinoceeos. 



A young male Rhinoceros, three years old, having died in the Zoolo- 

 gical Gardens of Dublin in April, 1865, the body was purchased, for £17, 

 for the Museum of Trinity College, and I availed myself of the oppor- 

 tunity of making a careful examination of his muscles. I was ably 

 assisted in the dissection by Mr. Macalister, Demonstrator in Anatomy 

 of the Royal College of Surgeons, and by a staff of medical students, 

 who relieved each other from time to time. The stench from the de- 

 composing blood was almost intolerable, and several of my assistants 

 were disabled by typhoid diarrhoea ; this I escaped myself, as I had 

 done on a former occasion when dissecting a Nylghau, which had died 

 of putrid fever, and whose blood after death seemed to communicate di- 

 arrhoea by its smell to almost every person in contact with the body. 

 Notwithstanding these difficulties, I was able to complete the entire 

 muscular dissection in person, the results of which cannot fail to prove 

 of interest to anatomists. 



Having made a careful post-mortem examination of all the viscera, 

 except the brain, I felt it my duty to lay the following Report before 

 the Council of the Zoological Society : — 



"School of Physic, Trinity College, 

 " Dublin, April 14, 1865. 



" Repoet on Death oe the Rhinoceeos. 

 " The Rhinoceros died at 4 a. m. on Thursday, the 6th inst., and his 

 body was opened in the new Dissecting Room of Trinity College on the 

 8th inst, at 1 p. m.
