VETERINARY SCIENCE AND PRACTICE. 93 



are included within a territory approximately 3 miles wide by 40 miles 

 long, in a well- developed section frequently crossed by tide-water 

 creeks or streams. These centers have all been found on fields border- 

 ing waterways and lowlands subject to tidal overflow on account of 

 faulty sluices or broken dikes. When the disease spreads, it invaria- 

 bly passes upstream. To account for this the author adduces proof to 

 show that carcasses of animals that have died of the disease are car- 

 ried upstream by the incoming tide and that they finally ground and 

 contaminate everything in their neighborhood. The carcasses are 

 shown to have come originally from the New Jersey shore, where the 

 disease evidently arises from germs brought in on skins used iu a 

 morocco factory. This assertion is supported by the fact that men 

 working in the factory and engaged in counting and softening the raw 

 skins have been attacked by anthrax. 



It is pointed out that there is often considerable difficulty in obtain- 

 ing the cooperation of farmers in eradicating the disease, notwithstand- 

 ing the rigid laws upon the subject, but that where the operator shows 

 evidence of protecting the owner of a herd by not giving undue pub- 

 licity to the occurrence of the disease, and exhibits an evident endeavor 

 to save him from unnecessary expense, there is a tendency to give the 

 cooperation desired, lie shows further that the laws of the State 

 should be so modified that each animal destroyed shall be appraised 

 and a bounty granted the owner which shall recompense him for his 

 trouble in cremating or burying the carcass of the victim. He further 

 states that the laws should be amended to include protective vaccina- 

 tion of exposed animals among the measures which the governor may 

 take in combatting contagious diseases. 



If these two measures are adopted, he thinks farmers will see the 

 justice of the heavy penalty now prescribed against concealment and 

 readily volunteer information. 



Relative to the vaccination of susceptible animals and their safety 

 after vaccination when turned upon infected pastures, the author states 

 that the protection that has been credited to vaccination is a real one, 

 although it may not be permanent. This is proven by the fact that vac- 

 cinated cows have been inoculated with anthrax poison without sickness 

 following, while the same poison in precisely the same amount has been 

 given at the same time to an un vaccinated cow with the result of its 

 death within 72 hours afterwards. The good results of the work are 

 shown by the fact that out of 19 herds vaccinated 17 escaped without 

 loss, and that of 331 cows vaccinated only 2 died of anthrax. 



Serum therapy in hog cholera, A. T. Peters (Nebraska 8ta. Bui. 

 47, pp. 57-67). — In a general way the author discusses antitoxin, and 

 briefly notes the results of serum therapy in tuberculosis, rabies, pneu- 

 monia, enteric fever, typhus, cholera, syphilis, streptococcus infection, 

 cancer, tetanus, diphtheria, snake bites, and swine erysipelas, in all of 

 which good or promising results have been obtained. The work at the
