instruction, and neatly bound in cloth in green and gold, with 
a horse on bended knee before his friend and master upon the 
cover, it is ornamental in appearance, and, with nearly three 
hundred pages of reading matter and illustrations, causes one to 
wonder how it can be furnished for the nominal sum of one 
dollar, postpaid. R. W. E. 
The Nature. Cause and Economic Importance of Ovine Caseous Lymph-Adfni- 
TIS. By Victor A. Norgaard, V. S. (Copenhagen), Chief of Pathological Division, 
B. A. I., and John R. Mohler, V. M. D., Acting Assistant Chief Pathological 
Division, B. A. I. 
The authors have forwarded us a copy of this paper, re¬ 
printed from the sixteenth annual report of the B. A. I., and it 
gives a very full account of their investigations into this little 
understood malady of sheep. The colored plates of microscopi¬ 
cal fields, as well as those of gross pathological anatomy, are 
excellent specimens of the lithographic art, and the biblio¬ 
graphical table places the reader in possession of all that can be 
found upon the subject in every tongue. The experimental 
work performed by the authors has been quite extensive, and 
their conclusions are clearly stated. The disease treated of is 
infectious, caused by the bacillus of Priesz, which is pathogenic 
to mice, guinea-pigs, rabbits and sheep, and non-pathogenic to 
chickens and pigeons. It is questionable to the minds of the 
investigators as to whether it affects horses and cattle, but a 
typical case has occurred in an Angora goat since their report 
was rendered. It prevails in certain districts of the western 
part of the United States, but owing to its benign nature and 
very chronic course its presence is seldom noticed except upon 
post-mortem. Fatal cases are practically unknown, and the 
loss resulting from condemnation of carcasses with extensive 
lesions is insignificant.
