not only of high scientific interest, but of great practical impor-

 alcohol, they should be packed in cotton saturated with alcohol. 

 In sending pinned or mounted insects, always pin them securely in 

 a box to be inclosed in a larger box, the space between the two 

 boxes to be packed with some soft or elastic material, to prevent

 the sender. 



In reply to numerous inquiries concerning entomo- 

 logical books, we recommend to the general student 

 'Harris on Insects Injurious to Vegetation,' and 

 Packard's ' Guide to the Study of Insects ; ' and to 

 those beginning the study, ' Insect Lives,' published 

 at one dollar by The Writers Publishing Company, of 

 New York. The last is the only book of low price we 

 know of that treats the subject so as to make it inter- 

 esting to the young.
