remained there three months in perfect health, and are still (Dec. 
1880) living and well. That the same causes were still in opera- 
tion, is shown by the death of the sheep already mentioned 
on July ;^lst. Moreover, it was definitely ascertained that on 
July 22nd sud-water, in which Van mohair had been washed, 
was sent down — this, no doubt, leading to the death of the 
sheep on July 26tli. On August 3rd another sheep was found 
dead, also from anthrax. 
It is at least remarkable that these animals should be found 
capable of resisting the contagion for such a length of time, and 
it appears to me to be fully conclusive of the protective value 
of inoculation. 
About ten days after the last heifer had been removed from 
the fields, having been upon them for four months, a cow, which 
had been placed upon the same field, died of anthrax under the 
following circumstances : — The proprietor had bought 11 Scotch 
heifers at the end of September, and kept them in the other 
fields not supplied with the sewage-water until November 23rd, 
when they were turned into the fields to which the sewage had 
been distributed. It must be added that, although some of the 
original sewage still ; remained in the cisterns, there had been 
no washing at the mill since the date above mentioned. On 
December 1 at 3 P.M., when the farm-bailiff went round, all the 
cattle appeared well, but on the 2nd at 8 A.M. he found one 
lying dead, apparently not having been dead long. Post- 
mortem and microscopical examination showed that the animal 
had died of splenic fever. 
With regard to the possible spread of the disease by the 
washing of infected wool, another very closely analogous case, 
which came under observation about the same time, may be 
mentioned. The circumstances were very similar. Fatal cases 
of anthrax occurred in wool-sorters employed in a mill, and at 
the same time five cows on a sewage-farm which received the 
sewage from the mill died of splenic fever. 
In reference to this subject it may also be mentioned that 
there is strong evidence that other materials capable of carrying 
the infection of splenic fever are sold for use in various ways in 
farms and elsewhere ; the bags in which the wool has been kept 
are sold, and used as sacking or cloth. It is worth while to bear 
this in mind, in considering the origin of apparently spontaneous 
and isolated cases of splenic fever. 
Few in number as have been the experiments made, owing to 
the costliness of the animals, and of their keep for a sufficient 
length of time to test the value of the inoculation, they afford 
sufficient evidence of its value as a preventive measure to en- 
courage further investigation. This is especially desirable, as
