SILVER PINS FOR COLLECTORS OP MICRO-LEPIDOPIERA, &c, 



as well as minute insects of all other families. 



We stock various sizes and lengths of these Silver Pins, which have certain 



advantages over the entomological pins usually employed. 



For instance, insects liable to become greasy and verdigrisy, like SesiidsB, 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.
