English literature is seriously deficient in articles referring to this disease. True, so far as we are aware, the malady only appeared in this country in 1902, following upon the war in South Africa, and no imme diate need of giving it attention had arisen.
Its prevalence in France, Sweden, India, Russia, Japan, China, Italy, Egypt, etc. etc, had not been considered of sufficient importance to demand the attention of Englishmen.
Seeing that the disease is so much like farcy, and excepting by means of microscopic inspection or mullein indistinguishable from it, there is no direct evidence of its absence from our studs, but we think and believe it has but recently acquired a footing in the country by the return of infected animals from South Africa.
A contagious and inoculable disease characterized by the development of abscesses and cording of the lymphatics of the skin. It-is essentially a local disease, due to a minute organism or cryptococcus which gains access to the tissues through an open wound. The organism is lemon-shaped, having one end slightly smaller than the other. It measures from 3 to 4 u in diameter, and is very easily found in the discharge with a suitable microscope. Seen by this means it presents a double contour, and is highly refractile. It is either free or enclosed in pus corpuscles.
The classification of the parasite is not quite clearly made out. As to whether it should be placed among the sporozoa or saccharomyces must be left for the present to those who have given the matter attention.
