dition of the contents, which are bloody. The blood itself is thin 

 and coagulates very slowly. 



Treatment. — The serum treatment would be the best for its 

 action upon the blood would kill the germs. Marmorek man- 

 'ifactured a serum which has been used with good results in some 

 cases and in others not. Use antiseptics and stimulants inter- 

 nally. Bichromate of potassium in one to three grain doses in 

 one or two ounces of water given 2-3 times a day will tend to 

 destroy the germs in the blood. In connection with this use 

 tincture of iron and sweet spirits nitre in liberal doses. Some 

 add a little quinine. The prescription is as follows:

SCARLATINA. 



Scarlatina is a very infectious disease, closely related to pur- 

 pura, but it has some prominent differentiating features. Some 

 have thought it a milder form of purpura but they have over-
