The winter succeeding the lessons on artdueology, J\Ir. 13. II. Van 

 Yleck, who had sjx'ut a considerable j)ortion of the previous summer 

 in prepai'iug specimens for this work, gave fifteen lessons on zool- 

 ogy. I'he study of tlie general morpliologv 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 ol)servation and study of 

 a limited number of types, 

 l)ut general points in physiol- 

 ogy and anatomy were also 

 taken up in a comparative 

 way. The microscope was 

 also used in this work. This 

 sjKH'ial coui'se was continued 

 during the next two terms. 



Dr. J. Walter Fewkes 

 gave a series of ten lessons, 

 during the winter of 1890— 

 '1)1, on Common Marine Ani- 

 mals from Massachusetts 

 Bay. Special attention was 

 given to the mode of life, dif- 

 ferences in external forms, 

 local <listribiTtion, habitats, 

 methods and proper times to 

 collect the eggs, young, and adults. The anatomy, embryology, 

 and moi'jdiology of the species considered were dealt wdth inci- 

 dentally. 



" The relative abundance of species and individuals, local causes 

 whi(di influenced distribution, the rocky or sandy nature of the 

 shores and their characteristic faunae, ami the influence of depth 

 of water tides and teni])eratui-e, were also considered.'' 



The relations and boundaries of the marine t'aumi of Xew Kng- 

 land were treated of under the following heads: Comparison of the 

 Fauna of Massachusetts Bay with that of Narragansett Bay and 

 the V,:\\ of Fuiidy, and Causes of the Differences Observed; Pelagic 

 Ainmals; Littoral and Shallow-Water Genera; Introduced and Tu- 

 <ligenous Marine Animals; and ]\rarine Animals which iidiabit both 

 P>rackish and Fresh Water.
