ordinary culture media, producing there conidia but not threads ; 

 copious thread production was, however, observed on beer-wort gelatin. 

 The fungus is distinguished from Monilia Candida by these peculiarities 

 and by its fermentation reactions, and is held by Plant to be a connect- 

 ing link between Zymonema and Endomyces. Intravenous injections 

 with rabbits induced nodule production in the kidneys but did not 

 produce fatal results. The name Parendomyce* pulmonalis Plaut, has 

 been given to the organism, in accordance with its origin. 



Micro-organism isolated in Scarlatina.* — M. J. Cantacuzene de- 

 scribes a new micro-organism isolated from cases of Scarlatina. The 

 organism is constantly found on the tongue and in the throat of 

 scarlatina patients, and has also been isolated in pure culture from the 

 miliary vesicles, which so frequently accompany the eruption. The 

 organism, which appears to be exceedingly pleomorphic, is either found 

 as isolated forms or as zooglcea masses. It stains generally with ordinary 

 basic aniline dyes, and exhibits characteristic staining with the Roman- 

 owsky stains — i.e. the appearance of chromatic bodies and an intensely 

 azurphile ground substance. The organisms are non-motile and are 

 decolorized by Gram's method of staining. The best growth is observed 

 on the surface of solid media to which defibrinated blood serum has 

 been added ; the colonies appearing as small transparent viscid points 

 which gradually coalesce. 



Pure cultures, injected subcutaneously into monkeys (Macacus 

 rhesus) produced a typical polyadenitis accompanied by fever and focal 

 desquamations. The temperature commenced to rise on the fourth day 

 and after reaching its maximum (41° C.) in one or two days, descended 

 by lysis. Post-mortem the animals showed signs of marked glandular 

 enlargement and vascular engorgement. The organism was recovered 

 from the spleen and other organs. 



Positive complement fixation experiments were carried out with 

 dilute emulsions of the organism and the serum of scarlatina con- 

 valescents. Controls made with normal serum were negative. 



Bacterium columbense.f — A. Castelkni re-affirms his statements 

 made in 1905 regarding the specificity of Bacterium columbense. This 

 germ produces in man a disease closely resembling typhoid fever of 

 medium severity, and the organism has been isolated from the stools, 

 urine, and blood of infected persons. In its cultural characters it 

 resembles other organisms of the coli-typhoid group. When freshly 

 isolated it is a non-lactose fermenter, but it acquires the power to 

 ferment this sugar after several transplantations. The growth on agar 

 is very luxuriant. 



The claim to the specificity of the organism rests, however, principally 

 upon its agglutination reactions. It is strongly agglutinated by the 

 serum of patients suffering from Columbense infection, which sera do 

 not agglutinate Bacterium typhosus, or B. paratyphosus A or B, even 

 in dilutions of 1 : 20. The bacterium is not agglutinated by the serum
