West Side. 
The friend and companion of Wm. Maclure, whose surviving brother 
erected this monument. 1846. A. M. 
North Side. 
Votary of Nature even from a child, 
He sought her presence in the trackless wild ; 
To him the shell, the insect and the flower 
Were bright and cherished emblems of her power. 
In her he saw a spirit all divine, 
And worshipped like a pilgrim at her shrine. 
Mr. Smith gave a brief review of specific characters in the 
genus Arctia, criticising the recent papers by Hulst, Neumoegen 
and Grote on the subject, and pointed out certain features in macu- 
lation which, in his experience, form constant and reliable specific 
characters.* 
Mr. Ulke made some remarks in regard to the exchange and 
sale of insects. He contended, that exchanges had the tendency 
to make collectors careless, and that these became more interested 
in possessing numbers of the check list than species. The ex- 
changes, facilitated by the check lists, added nothing to the ento- 
mological knowledge of the persons engaged therein. He had 
received large numbers of species to be named by him, and he 
invariably found that the majority of names obtained by exchange 
were wrong. The sale of insects in his opinion was even worse, 
many collectors actually forming a corner in some local or showy 
species. He further claimed that dealing in insects had the ten- 
dency to produce cheating and to give wrong localities. Mr. 
Smith contended that exchange between collectors was the only 
means by which beginners could hope to ever obtain sufficient 
material to enable them to study their favorite group.
