 The students in the laboratory are given opportunities of making for themselves a collection of microscopical specimens of most of the common tropical diseases. They are instructed in the examination of meat at the Hamburg slaughter-house. Advanced students are welcomed for research work in the Institute. Special lectures are given to nurses and missionaries who are proceeding to the tropics, and some lectures have been given to lay audiences. Illustrated postcards are published to instruct lay residents in the tropics.

The Institute has so far not been able to send any scientific expeditions to the tropics, but hopes are entertained that this will be possible in the near future. I may, however, mention that in 1904 Drs. Otto and Neumann proceeded to Brazil in order to study yellow fever, and in the following year Dr. Otto went to Togo, West Africa, for the same purpose. In 1906 Drs. Fiilleborn and Mayer travelled in Egypt, Ceylon, India, and East Africa, to study tropical diseases, and all these journeys have been amply utilised to enrich the pathological museum.

For teaching purposes lantern slides are largely employed, and there are some excellent coloured diagrams, which are shortly to be reprinted for sale.

In order to give every facility to students to study helminthology, sections of worms are placed vertically in stands with electric light behind them; the student examines these at leisure with a magnifying glass. There is a splendid collection of microscope slides for demonstration purposes, and a good supply of photographs. Tsetse flies are sent to Hamburg from the tropics in the pupa stage, so that they develop into mature insects either on board the ship or after arrival at the Institute.

I had the advantage of attending an epidiascope demonstration given by Professor Fiilleborn, when due honour was paid to the various workers of this country who have
