7. The ulcers on the teats correspond in naked eye and microscopical
appearances, and the latter vividly recall the appearances of cow-pox.
8. Calves inoculated from the discharges of the ulcers are similarly
affected.
9. _Post-mortem_ examination of such calves, or of calves inoculated
with streptococci isolated from scarlet fever cases, show similar
appearances.
10. The _post-mortem_ appearances in such inoculated calves are the
result of septicæmia.
11. There are no specific visceral changes in cow-pox, apart from
complications or coincident affections.
To the above criticism of Dr. Klein’s investigation of the Hendon cow
disease, this gentleman claims that Dr. Cruikshank studied a different
affection, and that the organisms were not the same. It is insisted upon
by Dr. Klein, that Dr. Cruikshank’s conclusions were the result of
studying cow-pox and not the peculiar disease he described as the Hendon
cow disease.
