— Mr. G. D. Smith, of Boston, died of paralysis August 6th, 
aged 46. He was a member of the firm of Palmer, Bachelder &

museums and entomologists by the loan and gift of specimens, 
and thus fostered the zeal of amateurs and local collectors. He 
was modest, amiable, generous and most industrious, and a loss 
to the entomologists of Cambridge and Boston, by whom he was 
held in high esteem. We understand that Mr. Smith’s collection 
is for sale; it would serve admirably as a general collection for a 
college or university museum.
