“Frank H. Lattin, of Albion, Orleans Co., N. Y.,a dealer in natural history specimens, 
instruments, supplies and publications of all kinds. Every A. A. Chapter should have a copy of 
his complete catalogue and price-lists before making purchases. His specimens are the very 
best, and his prices will be found to be much lower than those of any other reliable dealer.” 
The above we copy from Three Kingdoms, the Hand-Book of the Agassiz Association. Our 
readers would no doubt save money by complying with this advice.

prices low. HENRY HEMPHILL, P. O. Box, 1023, San Diego, Calif,
