 makes mention of the epidemic of diphtheria in Ischl, 

 where in December, 1895, all those children died who had 

 not received the antitoxin treatment; whereas in January, 

 1896, in the cases of 16 children attacked with the disease 

 and treated with antitoxin the result was in every way suc- 

 cessful. — The Lancet. 



A Newly Discovered Constituent of the Blood. — Dr. 



Muller of Vienna has described certain particles found in 

 the biood under the name of ha^mokocia (blood dust). 

 They resemble fat-g^lobules, and the larg-est are 1-25000 of 

 an inch in diameter. They are motile and are unaffected

The Serum Treatment of Cancer. — At a recent meet- 

 ing- of the French Cong-ress of Internal Medicine , M. Du- 

 bois stated that he had introduced frag-ments of cancer 

 taken from human subjects into the cellular tissue of ani- 

 mals and had obtained several tumors, the larg-est of which 

 weighed between seventeen and eig-hteen ounces. The 

 serum of these inoculated animals was then employed in 

 three cases of cancer. In the first case there was non- 

 ulcerative cancer of the breast in which the treatment led 

 to an almost complete recovery after a period of forty-five 

 days. The second case was one of epithelioma of the face, 

 which subsided in thirty-nine days. 



In each case, from two to five cubic centimeters of the 

 serum had been injected in the reg-ion of the tumor every 

 three da3's and a few drops of alcohol with a very small 

 quantity of iodide had been injected around the tumor in 

 the second case. The third case was one of relapsing- 

 epithelioma of the upper lip, which was very much ulcer- 

 ated and hig-hly inflamed, and after twenty-three days of 

 treatment the prog-ress of the tumor seemed to have been 

 arrested, but it presented no tendency to complete recov- 

 ery From these facts, M. Dubois concludes that the se-
