A FURTHER INQUIRY INTO THE REASONS 
WHY THE HORSE RARELY VOMITS. 
By Joseph Sampson Gamgee, 
Staff Surgeon of the First Class, and Principal Medical Officer of the 
British Italian Legion, during the last War. Late Assistant- Surgeon to 
the Royal Free Hospital ; President of the Medical Society of University 
College, and House Surgeon to University College Hospital. Member of 
various learned Societies, British and Foreign. 
The disputed question amongst physiologists concerning 
the act of vomiting in the horse, having been one of the 
objects of my earlier experimental inquiries, I published the 
results in the London Monthly Journal of Medicine in February, 
1852. The late Mr. Percivall honoured me by transferring 
my memoir to the pages of this periodical ; but through some 
curious coincidence, the printer altogether omitted reproduction 
of the foot notes, several of which contained facts and reflections 
directly bearing upon, and materially affecting the reading of 
the text. I thus laboured under the disadvantage of being 
misinterpreted by the readers of this Journal, and by the 
members of several learned societies on the Continent, who 
chanced to refer to the maimed edition of my 6 Inquiry/ and 
on it to found observations, the fallacy of which would, I 
presume to think, have been apparent and hence avoided ; 
if the physiological considerations I had developed, had not 
been in part accidentally suppressed. 
Under these circumstances, I propose making an abstract 
of my first f Inquiry/ commenting upon it according to the 
results of subsequent reflection, and appending an analysis 
of two elaborate memoirs which have recently been published
