74 SUMMAEY OF CUEEENT EESEAECHES RELATING TO 



Mycetozoa. 



Mycetozoic Infection of the Cornea.* — Dr. C. Gorini inoculated 

 the cornea of rabbits with Plasmudiophora Brassiae. This infection 

 was followed by tumour formation and ulceration. Very similar appear- 

 ances result from vaccinia infection of the cornea, but in the latter case 

 the corneal epithelium is chiefly involved, while in the former it is the 

 proliferation of the connective-tissue elements which causes the swelling. 

 The infection maybe transferred from rabbit to rabbit, and infected cab- 

 bage, preserved in glycerin, will retain its activity for sis weeks.

Colourable Granules in the Bacterial Cell.f — Under the imposing 

 title of morphological researches on the biology of bacteria, H. Marx 

 and F. Woithe record at considerable length their impressions of the 

 colourable granules in the bacterial cell. They find that these " Babes- 

 Ernst " granules are associated with the life-history of the species, and 

 are to be regarded as evidence of the highest importance of the vital 

 development of the species. The paper is illustrated by some coloured 

 drawings showing the effect of single and double staining. The pre- 

 parations were stained with methylen-blue (Loeffler, alcoholic, and acetic 

 acid) and afterwards with aqueous solution of Bismarck-brown. 



Occurrence of Acid-resisting Bacilli in the Lower Animals, i. — 

 Dr. D. M. Cowie has found acid-resisting bacilli in many of the lower 

 animals, more especially the horse, cow, dog, guinea-pig, and white rat. 

 No such organisms were detected in the rabbit and in the cat. Many 

 of these acid-resisting bacilli resemble the tubercle bacillus of the 

 smegma bacillus of man. These bacteria are undoubtedly of different 

 species, and there seems reason to believe that the term smegma bacillus 

 denotes not a definite species but rather a group of bacilli having common 

 staining properties. 



New Pathogenic Streptothrix § — Prof. Aoyama and Prof. Miyamoto 

 isolated from a case of pneumonitis characterised by lobar consolidation 

 and excavation a streptothrix, which was easily stainable by ordinary 

 dyes, by Gram's method, and by the tubercle bacillus stain. Cover-glass 

 preparations showed typical branched filaments, and these were also 

 present in micro-sections of the lungs. The organism was cultivated 

 on the ordinary media and also in sterilised water. Positive results 

 were obtained by injecting guinea-pigs with pure cultures. 



Two new Pyogenic Microbes. || — Dr. E. Klein found in the sero- 

 fibrinous exudate of the inflamed udder of a cow a bacterium designated 

 Streptococcus radiatus. Colonies on gelatin resemble small grey disks 

 with radiating processes ; on agar and blood-serum the growths are fairly 

 round with somewhat irregular border. Milk remains fluid and un-
