ing the vial before its contents were all used up. Using wrong 
virus. I have it on good authority that black-leg vaccine has 
been used on several occasions for anthrax lymph ; the reason 
for the error being, I presume, due to the fact that black-leg vac. 
cine is frequently labelled for symptomatic charbon or anthrax 
} 
and the operators being ignorant of the difference. Quite re¬ 
cently I have observed, through our daily press, that a number 
of cases of tetanus had followed vaccination for anthrax. It is 
difficult to account for this except through the proper precau¬ 
tions being neglected during the operation, through after-infec¬ 
tion of the inoculation punctures, or through virus infected with 
tetanus organisms. If the latter, it shows how completely the 
veterinarian is dependent upon the reliability of the manufac¬ 
turer and vender of these products. Want of due protection 
and care of inoculated animals before complete immunity is 
established, in the midst of an epizootic of anthrax, has also 
brought about indifferent results, etc. 
The best season to vaccinate in our climate is almost any 
time before the heated term, so as to permit of complete immu¬ 
nity before the climatic conditions appear that are favorable to 
the development of bacterial and insect life. 
Personally, I have vaccinated only a few hundred head of 
stock, the most of the work in recent years being done by prac¬ 
tising veterinarians, managers and owners of plantation and 
farm stock, a few physicians, and a number of u quack vaccina¬ 
tors.” Although I wrote to several practitioners in the State 
for the results of their experience with preventive vaccine, I 
failed to get a response in the majority of instances. 
I have a record from a physician who assisted in inoculating 
stock in the 1896 epizootic in North Uouisiana. During the 
height of the outbreak he vaccinated some 250 head of horses 
and mules with the Pasteur lymph. After the first inoculation 
about 3 per cent, showed symptoms of the disease, but not more 
than 50 per cent, of the 3 per cent. died. After the adminis¬ 
tration of the second lymph there were no more deaths, with 
only a few animals exhibiting symptoms. At the same time,
