464 Report of Work on Protective Inoculation for Anthrax, S^c. 
efficacy, we cannot recommend the use of Arloing's dried muscle- 
juice as a means of protecting cattle from the disease in Great 
Britain. 
The simplicity of the method of inoculation described, as well 
as its general practicability, favours its adoption. Inasmuch 
as some of our experimental guinea-pigs, after being " vacci- 
nated " with muscle-juice subjected to the effect of a lower 
temperature, resisted the influence of injected virulent matter, 
some of which killed cattle and other guinea-pigs vaccinated 
with Arloing's powder, further experiment in this direction 
should be made. In such case, and indeed in all, the result 
is likely to be incomparably more valuable and trustworthy 
if experiment for protection be made with animals of the class 
for which practical protection is sought. 
The Hodnet Hall experiments go very far to prove that 
the intravenous injection of considerable quantities of fresh 
virus is protective, and to a large extent practicable. The 
greatest drawback to its general adoption seems to be the 
necessity for fresh material with which to inoculate. This diffi- 
culty is not really as great as at first sight may appear. It at 
least has this in its favour, that it presupposes the existence of the 
disease on the estate, and does not encourage the chance of in- 
troducing fresh disease from without, as is probably the case 
with some systems of inoculation. 
Resulting from the publication of a report of the experiments 
at Hodnet by Major Percy, several stock owners have applied 
to us to have their animals protected by the intravenous method. 
In view of the results already obtained, we strongly advise the 
further and fuller adoption of this plan. 
In concluding our Report, we must again acknowledge our 
indebtedness to Mr. C. De Murrieta for placing animals and 
services at our disposal ; to Major Percy, whose untiring interest 
in the whole matter and great solicitude for the proper obser- 
vance of all details in connection with the Hodnet experiments 
have had no small share in the attainment of their success ; to 
Messrs. Bennett, Pyatt, Kettle and Barron, veterinary surgeons, 
who, together with other gentlemen before referred to, have 
rendered material assistance. 
After the above Report was written, one lot of 53 animals, 
belonging to Lord Egerton of Tatton, were inoculated, after 
the manner described in the Hodnet Hall experiments, with 
the virulent matter of Quarter 111, taken from an animal 
of the herd which died on the spot after the arrival of Mr. Pen-
