seum since this plan was adopted by several kindred institutions in America and in Europe.
A further effort to interest and instruct the youth of the community has led to the formation of a society known as the Andrew Carnegie Naturalists' Club, which consists of between two and three hundred young people who meet every other week on the afternoon of Saturday in the lecture-hall of the Museum and hear lectures, often illustrated by specimens and the stereopticon, and who read papers upon subjects of interest. During the summer months the club makes excursions in the neighborhood, and the various subdivisions receive practical instruction from the staff of the Museum in the art of collecting and preserving specimens of plants and animals.
The wider diffusion of knowledge among scientific men and institutions is provided for by the publication of the 'Annals' and 'Memoirs' of the Museum. The former appear in octavo form, the latter in quarto. This series of publications began with the first month of the twentieth century, and it is hoped will not end so long as the centuries run their course.
