Mr. FetherstonliaugK s Crotchets, — It appears to me some- 

 what odd that, with respect to Crotchet No. l,both Mr. Newman 

 and the Rev. Joseph Greene have quite passed by the question 

 raised. Mr. F.'s crotchet, as he very distinctly stated it, is 

 that strychnia, by its diffusive power, if inserted into the 

 thorax of the living insect would effectually ward off all 

 future attacks of miles, &c., from any portion of a specimen 

 so killed. This is a siniple proposition, which I, for one, 

 have been most anxious to see discussed and disposed of; but 

 Mr. Newman and Mr. Greene have gone off into a discussion of 

 whether camphor is synonymous with grease, and whether it 

 or benzole is the most pleasing to the olfactory nerves. Mr. 

 Fetherstonhaugh has not slated that strychnia, in its imme- 

 diate effect of producing the death of the insect, is at all to 

 be preferred to any of the modes of killing already before the 

 public, but he has suggested that its use may obviate the 

 necessity for having recourse to camphor, benzole, cajeput, 

 or any of the other strong-scented mailers, to which I would 

 apply Mr. Greene's remark, " de guslibus," &c. I beg to 

 suggest a crucial test : let an insect (say of the Bombycidae) 

 be killed in the manner suggested by Mr. Fetherstonhaugh, 

 and, when set and dry, placed in a drawer with insects 

 already affected with mites : if the insect killed with strychnia 

 escapes attack, then Mr. Fetherstonhaugh will have established 

 his point, and done good service to the science of Entomology. 

 I will not attempt to follow Mr. Newman and Mr. Greene into 

 the grease question ; Mr.Newman appears to abjure camphor and 

 suggest benzole; Mr. Greene likes the one and abhors the other.
