Temporary Insect Case. — A cigar-box with a sheet of cork 

 or a couple of layers of coarse white blotting-paper in the bot- 

 tom will serve very well for a temporary insect case for each 

 student. 



Put a few drops of turpentine or formaldehyd in one corner 

 to keep out hve insect pests. Use regular insect pins. Klaeger's 

 Nos. 3 and 4 are perhaps the most useful sizes. They may be 

 obtained from dealers in naturalists' supplies.
