much for cyanide. 1 All butterflies, except the larger Skippers, travel

size. Larger envelopes are requisite for Papilios, while smaller suffi ce 
for Lycaenids. The number, date, locality and remarks may be written

corresponding to the specimens. Note-books should be strongly 
bound, but must open well; the paper should be of the best quality 
so as not to “ dog’s-ear.” They can be made and ruled to order by a
