 contnined on tlio average 30 to 50 gm. of lactose per liter, were concentrated. '

 Orleans method. The product obtained was of a clear, bright yellow color and

VETERINARY MEDICINE. 



The effect of smelter fumes upon the live-stock industry in the Northwest, 

 R. J. FoRMAD (V. 8. Dept. Agr.. Bur. Anim. Indus. Rpt. 1908, pp. 237-268. pi. 1, 

 figs. 7). — The effects of smelter fumes on the live-stock industry and on forage, 

 as previously noted from other sources (E. S. R., 20, pp. 28, 790) are briefly 

 reviewed and investigations reported. 



In response to appeals from stock growers and farmers who had sustained 

 losses of stock and crops, the author conducted investigations from October to 

 December, 1906, in the Deer Lodge Valley, Montana, at distances on an air 

 line of from 1^ to 12 miles from the Anaconda smelter. Information obtained 

 as to the holdings of 49 persons indicated that losses had caused a decrease 

 from 2,447 horses, kept in 1902, to 423. 



An experiment made to test the effect of arsenic on horses in which 20 

 grains of white arsenic was fed to a horse on August 29 and 40 grains the 

 following day resulted in the death of the animal on September 6. Arsenic 

 ulcers similar to those found among horses in the vicinity of the smelter were 

 produced through the application of an arsenical paste of semiliquid con- 

 sistency to the nasal septum by means of a svA^ab of cotton. The clinical symp- 

 toms shown by cattle and horses in the Deer Lodge Valley are described at 

 some length. Post-mortem examinations made of 22 cases are briefly reported 

 as are the microscopical-anatomical studies of samples taken at the autopsies 

 of 12 cases. 



" The pathologic findings on post-mortem examination show unmistakable 

 lesions of chronic catarrhal inflammation of the stomach, intestines, lungs, and 

 kidneys. The microscopic preparations demonstrate conclusively the presence 

 of a pronounced irritant, which has operated on all organs pertaining to the 

 metabolism and assimilation of food, as well as those concerned in the elimina- 

 tion of' waste products, being characterized by an inflammatory cell prolifera- 

 tion in the mucous membrane of the stomach and intestines, the portal areas of 

 the liver, the peri-bronchial connective tissue of the lung, and the interstitial 

 connective tissue of the kidneys. These cell infiltrations of proliferations can 

 be the result only of an irritant, which on chemical analysis has proven to be 

 ai'senic." 



A bibliography of the more imi)ortant literature relating to the subject is 

 appended. 



[Report of veterinary division], M. H. Reynolds (Minnesota 8ta. Rpt. 

 1908, pp. XVI-XXI). — In this report brief mention is made of the work of the 

 year on ventilation and with hog cholera, swamp fever, tuberculosis, and in- 

 fectious abortion. The use of hog-cholera serum on normal hogs is stated 

 to have given exceedingly satisfactory results. Experiments have shown that 

 the common laboratory animals are not suscejitible to swamp fever.

 W. B. Mack (Nevada Sta. Bui. 66', pp. 53-02, 65-68. pis. 2).— During the year 

 under report several chickens from Reno were examined and found to be affected 

 with tuberculosis. A flock of sheep inspected was found to be infected with foot-
