Professor Jolyhas devoted himself to zoological re- searches on (Estridse in gen- eral. Professor Schroeder Yander Kolken, in Holland, and Mons. Brauer, in Aus- tria, have studied them with great success. The Hippoboscus is a fly which is very greedy of blood, and attaches itself to horses and oxen, especially under the tail, in the parts where there is less hair. It sometimes also attacks man.
