REVIEW. 
The division of the subject matter into chapteis, comprising 
diseases of the blood (non-specific haemal affections, specific hae¬ 
mal affections and poisons) ; diseases of the circulatory system ; 
diseases of the digestive system, &c , &c., not only facilitates the 
study of any one particular disease, but also brings distinctly be¬ 
fore the mind of the reader the differential characters of the va¬ 
rious diseases affecting the same system or group of organs. 
“ Parasites and parasitism us,” is of much value to the practitioner 
in enabling him to recognize the most common of the parasites 
that infest the bovine family. The engravings very materially 
enhance the value of the work. 
Had most of the space devoted to the introduction been 
utilized iu giving more comprehensive descriptions of the various 
diseases, the work would not then be open, as it now is, to the 
criticism of seeming to slight some very important subjects. 
“ Diseases of the Ox ” merits a prominent place in the library of 
every veterinarian and veterinary student.

our readers an opportunity to read it, as we had been given to 
understand that we could obtain the volume. As we were going to 
press we received notice stating that we cannot have the reports 
for our own distribution, but that a copy can be had from Wash¬ 
ington on application. 
The report is made to discuss the points of inquiry relating to 
the investigations made bv the Doctor when in England, where he 
had been commissioned last year for the detection of contagious 
pleuro-pneumonia in American cattle sent abroad ; also to present 
the report of Dr. W. T. Whitney, the microscopist, who examined 
portions of diseased lungs brought home from Liverpool, and to 
draw reasonable deductions from the facts presented, giving first 
the history of the animals from which the condemned lungs were 
obtained. The microscopic appearances of all are- carefully
