direction and advice. It was believed that such a laboratory would meet the wants of many teachers who had attended practical lessons in The Teachers' School of Science. Twenty-two persons—ten women and twelve men (nearly double the number expected)—availed themselves of the privileges offered. The summer work, which was very successful, was due to the ability and energy of Mr. B. K. Van Vleck, who had the whole charge of the instruction and work done in the laboratory. The seaside laboratory continued to be used successfully in the same way during seven consecutive summers, and the work of the laboratory materially influenced the future science teaching in several colleges and in many William O. Crosby. public schools of this country. In 1886 Professor Hyatt called the attention of the Woman's Education Association and the society to the fact that the laboratory had reached a stage when it could claim the support of patrons of science and learning, and be placed on an independent and permanent foundation. The two associations accordingly called a meeting, made up largely of the representative teachers of biology, who decided to make an effort to establish a permanent biological laboratory and raise at least fifteen hundred dollars to carry it on for five years. The result was the foundation of the Marine Biological Laboratory, at Woods Holl, which now attracts to its general courses teachers and other students from all over the land, and also maintains a department for special research work.

In 1882 agents were obtained, by correspondence and through the kindness of the Secretary of the State Board of Education, Mr. Dickinson, in forty-four towns, who distributed tickets and filled out blanks so that the benefits of The Teachers' School of Science were extended beyond the limits of Boston. In this year there were two courses, one of ten lessons, by Professor Niles, on physical geography, and five on physiology, by Dr. H. P. Bowditch. These courses began in November and continued throughout the whole year, with
