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.
THE CAUSE OF DEATH IN PHTHISIS.
Dr. R. W. Philip has made an experimental study to determine the cause of death in phthisis. The results of his study are published in the Brit. Med. Jour. of Jan. 28th, 1888.
His experiments were conducted with an extract prepared from fresh sputum from phthisical patients, as follows:
The sputum was treated with alcohol, put in a sterilizer, and heated to 37 to 40° C. for some time, filtered clear, and evaporated at a low temperature until the alcohol was expelled. This extract was used for subcutaneous injections in frogs, mice, and rabbits.
