The winter succeeding the lessons on archæology, Mr. B. H. Van Vleck, who had spent a considerable portion of the previous summer in preparing specimens for this work, gave fifteen lessons on zoölogy. The study of the general morphology of animals was made under advantages such as had never before been offered in this school, and enabled teachers to see and study structures not usually within their reach. The work was mainly directed to the observation and study of a limited number of types, but general points in physiology and anatomy were also taken up in a comparative way. The microscope was also used in this work. This special course was continued during the next two terms.

Dr. J. Walter Fewkes gave a series of ten lessons, during the winter of 1890-'91, on Common Marine Animals from Massachusetts Bay. Special attention was given to the mode of life, differences in external forms, local distribution, habitats, methods and proper times to collect the eggs, young, and adults. The anatomy, embryology, and morphology of the species considered were dealt with incidentally.

"The relative abundance of species and individuals, local causes which influenced distribution, the rocky or sandy nature of the shores and their characteristic faunæ, and the influence of depth of water tides and temperature, were also considered."

The relations and boundaries of the marine fauna of New England were treated of under the following heads: Comparison of the Fauna of Massachusetts Bay with that of Narragansett Bay and the Bay of Fundy, and Causes of the Differences Observed; Pelagic Animals; Littoral and Shallow-Water Genera; Introduced and Indigenous Marine Animals; and Marine Animals which inhabit both Brackish and Fresh Water.

It having been found that for several years the audiences at
