Chiefly interesting for the very complete bibliography it contains of 
the earlier notices on the eyes of Arthropods. Chatin’s methods 
were so primitive that his work is otherwise of little value.

Figures of the eyes of Hippoboscide, Céstride, Syrphida, Muscide, 
Empidz, Leptide, Asilida, Bombylida, Tabanide, Chironomide, 
Tipulidae, and Pulicida. (No kind of nerve terminal is represented 
except in the Ocelli. All his sections were evidently thick, and the 
structure of the true retina is not clearly figured.)
