terflies from the eggs at different seasons, but especially, if the seasons 

 are strongly marked, at the commencement or at the end of each change. 

 My experiments have as yet been applied to four species only, and I 

 think I may safely say that the results to most entomologists are most 

 unexpected. I could indicate many dozens of Indian species in which 

 I believe this seasonal dimorphism to occur, embracing nearly every 

 family into which butterflies have been divided, but I might be again 

 accused of " guessing." The subject is a most interesting one, and I 

 hope to revert to it again before long.
