})oit50uhiy on I'otato beetles. Yeiist tis an insecticide is so mnch 

 less objectiontible than Paris-Green, that every one possessing com- 

 mon sense and a regard for the welfare of his fellow men and the 

 domestic animals shonld hail the discovery with pleasure. We think 

 Mr. Saunders' Insect Powder will be best for Greenhouse use and 

 in the house, and the fungoid poisoning for out of doors, Avhen the 

 length of time, which it takes to infect the insects, will be less 

 of an objection. Prof. Riley, who has identified himself with the 

 use of Paris Green in his puldications, is reported as having ol)- 

 tained "Pcsults, Nil I" from yeast. But as no particulars of his 

 experiments are given, we hope they will be thoroughly tried over 

 again. The results of the use of Paris Green are not "Nil !''; 

 among them may be given the death of the farmer's stock and his 

 neighbor's, the poisoning of innocent people as Avell as those who 

 unadvisedly use the poison, and the permanent injury to the land. 

 Potato skins should now be carefully handled and not fed to stock; 

 a fresh instance of fatal poisoning in this way having recently 

 come under notice in the daily press. Dr. Le Conte recom- 

 mended experiments in fungoid poisoning in 187-i. For the cur- 

 rent-worm the yeast poisoning should certainly Ijc tried and also 

 for the cotton-worm. Both these pests offer an excellent oppor- 

 tunity for experiment with yeast. [See N. Am. Ent. p. 23 for a 

 notice of Dr. llagen's paper in Can. Ent. on this same subject.]'
