knowledge that erysipelas has done good in some cases of tumors 

 of the skin, the following procedure was carried out: Some of the 

 fluid containing bacteria of the fourth generation was taken, and in- 

 oculated by five punctures into the surface of a tumor situated on 

 the left buttock; four days later genuine erysipelas and high fever 

 set in. The whole erysipelatous process lasted ten days and ended 

 in recovery. The smaller .superficial nodules on the tumor became 

 softer and completely disappeared during the first few days of the 

 induced erysipelas, but the main mass only diminished a little in 

 size. — London Med. Times and Gazette. 



Tubercle Bacilli in the Urine. — Professor Rosenstein, of 

 Leyden, has described a case in which bacilli were found in the 

 urine in considerable numbers, and it is an instance in which the 

 discovery of uro-genital tuberculosis was otherwise equivocal. The 

 presence of the bacilli of tubercle in the pelvis of the kidney has 

 been demonstrated in the dead body by Lichtheim, but they have 

 not until now been found in the urine during life. — Lancet. 



Bacterial Pathology.— The Lancet furnishes the following 

 comments: Among important observations which have been pub- 

 lished recently regarding the relation of bacteria to disease, three — 

 concerning syphilis, whooping-cough and dental caries — deserve 

 especial mention. Aufrecht, Birch-Hirschfeld and others have pub- 

 lished observations as to the occurrence of special organisms in 

 syphilitic new formations, and some further investigations have lately 

 been conducted by Dr. Morison, of Baltimore, at Vienna, in a 

 clinique of Professor Neumann. In fifteen patients under treat- 

 ment he found bacilli constantly 'present in the pus collected from 

 the surface of the chancres and in papular syphilides. The organ- 

 isms were present in the deeper parts of the exercised papules, and 

 in the blood which escaped from the exposed surface. The pus was 

 collected by means of a wire previously heated in a flame, and 

 placed on a cover-glass which had been heated in a similar manner. 

 The pus on the glass was then dried, warmed at the flame, immersed 

 first in acetic acid, and then in absolute alcohol. After a fresh 

 desiccation, it was treated with methyl blue or with fuchsine. At 

 the end of half an hour the specimen was immersed in a solution of 

 nitric acid (1 in 6). A microscopical examination then showed an 

 immense quantity of cylindrical bacilli, readily distinguished by
