United States vs. Canadian cheese in England, Dickinson ( U. S. Consular 

 Bpts., 1898, No. 212, pp. 109-111). — Statistics are quoted on the export of cheese from 

 Canada and the United States to England. Considerable more cheese was imported 

 from Canada than from the United States. The Canadian cheese was valued at 9.12 

 cts. per pound and the United Stales cheese at 9.23 cts. 



VETERINARY SCIENCE AND PRACTICE. 



On a new infectious disease of cattle, ('•. Bosso {('entbl. Bald. u. 

 Tar., 1. . I bt., 22 1 189? ), No. 18-19, pp. 537-542, pi. 1). — A disease discov- 

 ered in the neighborhood of Pavia. rtaly, is described which is similar 

 to eharbon or hemorrhagic septicemia, but can not be classed as either. 

 It appeared suddenly, developing the following symptoms: Tempera- 

 ture, 30° C; cud-chewing slow, almost none; weakness in the lumbar 

 region and hinder parts; continued attempt to pass feces; suffering 

 severe. After three or four days the animal's strength disappears and 

 it succumbs, moaning painfully. 



In a herd of 21, 6 died. The disease was found on wet places and has 

 been observed on dry or high ground. Infection appears to be through 

 drinking water and food. Autopsy showed the heart, caronal arteries, 

 and veins about the sulcus ariculo ventricularis crowded with ecchy- 

 moses from the size of a needle point to that of a needle head. The 

 entire surface of the ventricles was covered with them. The blood was 

 reduced to a thin coagulum. The cardial lymph vessels were very 

 noticeable and were abnormally swollen. The kidneys were very 

 hyperemic, dark red to violet, inclined to black. 



Culture studies brought to light a motionless bacterium li // by 0.5 

 to 0.8 /i in size, which resisted many of the usual staining reagents and 

 withstood Gram's decolorizing method. Some obtained from the kid- 

 neys, where they are very numerous, measured 2.7 // long. Injection 

 experiments with guinea pigs, dogs, and white mice resulted fatally in 

 18, 18 to 24, and 00 hours, respectively. 



Histological studies showed that the chief alterations occur in the 

 Maipighian glomerules of the kidneys, where there was found great 

 changes in the vascular walls and a great increase in the number of 

 muscles in the endothelium of the vascular loops and the scaling of the 

 outer epithelium of Bowman's capsules, all of which may be character- 

 ized as Glomeruli) nephritis. The specific organisms can be found in 

 large numbers inside the vessel cells in the lymph spaces. 



The disease is very different from the new septicemia with nephritis 

 described by Thomassen as occurring in cattle, some of the differences 

 appearing in the turbid urine in the latter disease and the motile 

 organism. The organism is also distinct from that found in cases of 

 nephritis found by Hess, Pflug, Mazanti, Rivolta, Mircoli, and others. 



Some diseases of cattle, N. S. Mayo (Kansas Sta. Bui. 69, pp. 103- 

 134, figs. ?). — This gives a brief popular account of Texas itch, black- 

 leg or symptomatic anthrax, tuberculosis, and Texas fever.
