The winter succeeding the lessons on archaeology, 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 zool- 

 ogy. 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 physiol- 

 ogy 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 Ani- 

 mals from Massachusetts 

 Bay. Special attention was 

 given to the mode of life, dif- 

 ferences 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 inci- 

 dentally. 



" The relative abundance of species and individuals, local causes 

 which influenced distribution, the rocky or sandy nature of the 

 shores and their characteristic faunae, and the influence of depth 

 of water tides and temperature, were also considered." 



The relations and boundaries of the marine fauna of New Eng- 

 land 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 In- 

 digenous Marine Animals; and Marine Animals which inhabit both 

 Brackish and Fresh Water.
