THE "ALL GLASS MOUNT"

for _Lepidoptera_ and other insects

We are able at last to offer our customers an all glass mount that we believe comes nearer to meeting the requirements of museums and private collectors than any previously put on the market.

No cut can properly show this mount, which must be seen to be appreciated. Write for Circular 192, which describes fully what we are offering.

When in need of Entomological supplies remember that we have the best insect pins on the market and that our hand made Schmitt insect boxes with three ply tops and bottoms are unsurpassed. Catalogue No. 33 free on application.

Prompt shipments can be made from our large stock of United States and exotic insects of all orders. We also prepare 150 different metamorphoses of beneficial and injurious insects. Pupae now on hand are listed in circular No. 198. Other circulars and price lists free upon request.

Pomona College

Located in one of the most healthful and beautiful parts of the west coast. The mountains reach an elevation of ten thousand feet within a few miles of the college and these with the nearby ocean afford many special advantages for the study of things not in books. Special advantages are afforded by the fact that the college limits its attendance, the freshman class being restricted to two hundred applicants. The success of the college is particularly indicated by the large proportion of the graduates who proceed to advanced work in the large universities. In addition, well-manned departments of music and art afford exceptional advantages.
