are " sparkling, colorless bodies, something like 

 those found in vaccine, but larger." Some were 

 spherical, others were elongated, with sharpened 

 ends. The breath of healthy children did not 

 contain these sparkling bodies. These bodies 

 were also found in the lungs and liver of two 

 children who died of measles. 



Keating has recently (1882) reported the find- 

 ing of micrococci in the blood of malignant 

 measles, and their absence in cases of mild type. 

 He says : " The micrococcus is found in the con- 

 tents of pustules and vesicles, and also in the 

 blood taken from the measles-papule in mild 

 cases, without its being present in the blood taken 

 from the punctured finger. In severe cases, called 

 malignant in this paper, owing to the rapid ap- 

 pearance of morbid symptoms, the blood shows, 

 early in the attack, numerous patches of micro- 

 coccus in the field." These observations were 

 verified by Formad. 



PLEURO-PNEUMONIA. The infectious disease 

 of cattle known as pleuro-pneumonia has been 

 studied experimentally by Willems, Banti, Bouley, 

 Leblanc, Bruylants, Verriest, and others, and 

 strong evidence has been adduced in favor of the 

 view that it is due to a parasitic micro-organism. 

 In 1852 Willems pointed out the existence of 

 certain peculiar corpuscles in the lymph obtained 

 by incision of the lung of an animal dead from 

 this disease. This observation has been confirmed
