Injurious Properties. In parts of the country where these onions grow 

 there is frequent complaint of milk taking the flavor of onions where cattle 

 feed upon them. Chesnut and Wilcox do not mention any species of the genus 

 Allium, except some of the species found in Montana, which may impart to milk 

 a disagreeable flavor. Friedberger and Frohner state that onions produce 

 slavering. 



Prof. A. Liautard * has prepared an abstract of a report by Dr. W. W. Gold- 

 smith in the Journal of Comparative Pathology and Therapeutics upon onion 

 poisoning in cattle. Briefly it is as follows: 



Loads of onions partly started to shoot and partly decayed, were unloaded in a 

 meadow where nine head of cattle were grazing. After a week the cattle seemed sick
