664 SUMMARY OF CURRENT RESEARCHES RELATING TO 



the top surface of the medium was an irregular colony, whitish and 

 warty in appearance. The gelatin was not liquefied. On agar and 

 solidified blood-serum whitish irregular and raised colonies were de- 

 veloped. Broth became flocculent without surface pellicle. On potatoes 

 the colonies were raised at the edges. The indol reaction was negative. 

 Anaerobic growth was slow. 



A loopful of the culture caused death of a rabbit in about 48 hours, 

 and the micro-organism was found in the spleen and blood. Guinea- 

 pigs and mice died in 40-60 hours. Fowls were unaffected. 



The author was able to produce a certain degree of immunity in 

 rabbits by injecting them with increasing quantities, 2-20 cm., of the 

 filtered broth culture. 



He considers the micrococcus a hitherto undescribed species and 

 names it Micrococcus agilis albus.
