Diarrhoea in Children and Milk. — It is well-known that 

 milk mav g-ive rise to intestinal disorders traced back to 

 the poisonous products produced by micro-org-anisms. 

 Dr. K. Alt indicates in a paper in Deutsch. Med. Noch- 

 euschr, 1896, No.5, that all troupes of this kind need not 

 necessarily be referred back to micro-org-anisms, but in 

 some cases the food consumed by cattle may be responsi- 

 ble for some of this poisoning-. In the cases referred to 

 clover was thoug-ht to have caused the trouble. All pre- 

 cautions for sterilization seem not to have been taken into 

 consideration. Dr. Alt's conclusions are not warranted. 



Tsetse Fly Disease or Nagana in Zululand.- Dr. Bruce 

 claims to have traced the connection of this disease and 

 larger domestic animals to one of the Flagellatis (Trypan- 

 osoma evansi) which is carried over by Tsetse lly. It was 

 show-n that the fly was not poisonous, but that when the 

 fly was allowed to take the blood of a diseased ilog- it could 

 carry the disease to another animal, dog, horse, or bovine.

NEW PUBLICATIONS. 



Medical Botany. — Moquin-Tandon has published an 

 elementary treatise of 543 pages on this topic which con- 

 tains numerous lig-ures of medical jdants some excellent, 

 others rather poorly executed. The pai^t dealing with 

 phaenogams is good but the part dealing with cryptogams 

 is not up with the times, some rather remarkalde state- 

 ments being- made. Just two pag-es are devoted to bacteria 

 Leptothrixfuccalesand Merismo])idia (Sarcina ventriculi). 

 His information ccjncerning- these is somewhat ancient. 

 Reference is made to this ])art of the work because it is a 

 sample of what one finds too frequently in so called scien- 

 tific publici»tious.
