SUPPURA TION. 207 In spite of the small number of cases studied, they were of the opinion that their coccus is the specific one. Its is about i fj. in size and resembles the gonococcus, though it is smaller. The cocci generally lie in the cells, sometimes 8 or 10 in one pus cell, and are occasion- ally distributed throughout the pus in long chains or strings. They stain readily with the usual aniliu dyes, especially with Loffler's methylene-blue, and can be decolorized by the Gram method. They grow slowly upon the ordinary media, forming living, transparent, dew-like points on agar-agar. These little drops do not coalesce. In peptone-bouillon they form white, rather granular than flocculent deposit, the bouillon itself re- maining clear. The growth is said to be more rapid in strongly than feebly alkaline media. The cocci are said to grow upon ascites-fluid and upon milk, the latter coag- ulating in the course of forty-eight hours. They are capable of slight movement. Numerous inoculation ex- periments were made, only one animal, a white mouse, succumbing. Control-experiments failed to disclose "the same organisms in the healthy human parotid or its se- cretion. All the observers agree in finding in the secretions of the gland and in the blood diplococci that grow slowly, produce small colonies, aiid coagulate milk. No one has shown their specificity by inoculation, evidence of course necessary before the claim of real importance can be accepted.
