SILVER PINS FOR COLLECTORS OF MICRO-LEPIDOPIERA, &c., 



as well as minute insects of all other families. 

 We stock various sizes aud lengths of these Silver Pius, which have certain 



advantages over the entomological pins usually employed. 



For instance, insects liable to become greasy and verdigrisy, like Sesiidse, are best 



pinned on Silver pins, which will last much longer than the ordinary pins (whether 



enamelled black, or gilt, or silvered). 



We shall be pleased to send pattern cards on application.
