Considerable data are given on the physiological action of arsenic. Experi- 

 iiients with sheep show thtit 46 nig. (0.7 grain) of arsenic trioxid per day, 

 adniinisteretl in the form of sodinni arsenite per 100 lbs. of body weight is 

 sullicient to cause the death of a sheej). Digestion experiments made to deter- 

 iiiiiie the amount of arsenic in plants that is soluble in the digestive juices of 

 animals are rei)orted. A detailed account is given showing the distribution of 

 • irsenic in the tissues, the milk, ulcers of the nose, and in tlie hair. Symptoms 

 (if the chronic arsenical poisoning caused by the vegetation of smelter regions 

 are de.scribed.

The foot-and-mouth situation, I.. Teakson (Xat. Stockman and Farmer, 

 ,U UDOS), Xo. 37, p. 870). — Extracts from a letter in which an account of 

 the work of eradication of this disease in Pennsylvania is described. Up to 

 December 7, 94 infected herds had been found in the State. It is stated that 

 all of the infection in Pennsylvania traces to Buffalo from which at least 9 

 infected carloads wei'e sent into different localities about November 1. 



Johne's disease in cattle, W. L. Beebe (Amcr. Vet. Rev., 33 (tOOS), Xo. 6, 

 /)/(. 7i/'.i-7l6, jiffx. 3). — Attention is called to the fact that chronic enteritis 

 exists in the northwest, particularly in Minnesota. An account is given of 

 several cases, of the symptoms, and of a post-mortem examination. The author 

 concludes that there is very little room for doubt that the bacillus found so 

 abundantly and so uniformly present is the cause of the disease, although 

 attemi)ts by the author and others to infect rabbits and guinea pigs have 

 failed as have also attempts to cultivate the bacillus on artificial media. The 

 disease is regarded as infectious and of grave importance. The author recom- 

 nn'uds that all affected animals be isolated, that the feces be deeply buried or 

 liurncd, and that after a positive diagnosis has been made all animals be de- 

 stroyed. References 1o the literature are given. 



Experiments with English and South African redwater, A. Tiieilkr (7'>y/h.s-

 witli heifers in England and South Africa the author concludes that English 

 redwater is not always inoculable, and that it differs in this respect from 

 South African redwater.
