1894-1 283 [Annual Meeting. 
over forty well-determined species. A carefully selected and 
nearly complete series of these fossils has been added to the illus- 
trations of the local geology in Room B. During the collection 
and study of these drift fossils facts have come to light which 
indicate that they may be of late Tertiary instead of Quaternary 
age; and, although no certainly extinct species is yet known, 
it appears not improbable that Tertiary strata now underlie the 
deeper parts of Boston Harbor." 
The arrangement of the sjjecimens to iUustrate the geology of 
the Boston Basin has been commenced in sections 24 to 2G of the 
Avall-case in Room B. The collections for Nantasket, Cohasset, 
and Hingham are now in order, and it is proposed to extend the 
series with the completion of each part of the work. It is hoped 
to make this exhibit so effective that it will prove of real value to 
teachers and students, serving not only to ilhistrate the text, but 
for the identification of material collected or observed in the field. 
Through the generosity of Mr. Watson, three reading tables 
have been added to the Geological Department. These have 
been placed in the Vestibule, Room A, and Room B, and pro- 
vided with copies of the Mineralogical and Geological Guides, 
and Part I. of the Geology of the Boston Basin. This innovation 
is evidently a])preciated by the public, for although the books are 
in quite constant use on exliibitiou days, they have received as 
yet no serious injury. 
Botany. 
Mr. John Cummings still continues to take care of this collec- 
tion, and the indebtedness of the Society to him has been increased 
by another year of service. Owing to unavoidable delays and 
to unusual demand upon the time of the assistant by outside 
work, the final and complete report upon the herbarium cannot 
be given as was expected. Miss Carter has, however, been able 
to accomplish considerable in the various parts of the collection. 
A large amount of time has been devoted to the Fungi, the col- 
lection of which has been enriched by the addition of two foreign 
collections, and now contains 321 genera, 2,239 species, and 4,024 
specimens ; the fascicles of Seymour and P^arles's Economic Fungi, 
as far as published, have also been obtained. The following acces- 
sions are hereby acknowledged : Miss Cora H. Clarke, 67 speci-
