of the laboratory they lived but a few days. The author advises farmers owning 

 as many as 25 sheep to obtain good dipping vats. For smaller numbers than 

 this scalding barrels will do. Plans are given of. the dipping vat in use at the 

 station.

Disease among- sheep at Yallinup, R. E. Weir (Jour. Dept. Agr. West. 

 Aust., JS (,1009), j\"o. 5, p. 365). — A disease, in which the chief symptoms are 

 general debility, dropsical swelling in the lower maxillary space, and weakness, 

 particularly of the hind quarters, is reported to have been the source of a 

 serious mortality among flocks of sheep during the past 12 months. 



Veterinary section, J. PI. McNeil and C. H. Stance (Iowa State Col. Agr. 

 Rpt. 1907-8, pp. 161-166). — This report consists of a discussion of hog cholera. 



Six experiments in which the serum-alone and serum-simultaneous methods 

 were employed are briefly described. It is stated that no animal became sick 

 as a result of treatment nor did any untreated hog become sick while run- 

 ning with treated hogs except when sick untreated animals were in the same 

 pen. From these experiments the authors draw the following conclusions : 



" The serum of the blood of hogs hyperimmunized by injections of large 

 quantities of disease-producing blood will protect susceptible hogs for a 

 variable time against quantities of disease-producing blood sutficient to kill 

 non-immune animals. 



" The same serum will protect susceptible animals against infection during 

 exposure to natural outbreaks of the disease such as occur on Iowa farms. 



" Hogs injected with serum and virulent blood at the same time will resist 

 the disease when exposed to natural outbreaks or artificial inoculation of 

 disease-producing blood. Undoubtedly young pigs will acquire lasting im- 

 munity if they are treated with serum and immediately exposed to infection."

Tuberculosis of fowls, S. F. Edwards {Ann. Rpt. Ontario Agr. Col. and Expt. 

 Farm, 34 {1908), pp. 128-135, figs. 4).— During 1908 19 fowls affected with tuber- 

 culosis were received. Many farmers reported that they had lost a fowl or two 

 occasionally, and that the loss is gradually increasing, while 2 farmers stated 

 that they had each lost about 100 within 2 years, and a third reports that he 

 has lost one a week for over a year. Tuberculosis of birds is said to be con-
