[Annual Meeting. 
Tlie room of tliis department lias been used as in previous 
years by three classes from the Boston University and by two 
classes of the Teachers' School of Science. The use of this 
room was also granted to an advanced class of the Normal 
School which has occupied it for finishing the course begun in 
Maj^, 1894, and another similar course has been begun in the 
same room but is not yet finished. 
Considerable work has been done by Mrs. Flint in numbering 
the specimens of the collection, in preparation for a new cata- 
logue, the old one having become useless on account of the 
numerous changes in materials. 
Mr. Grabau has done some woi-k on this collection and has 
donated a few specimens of Columnaria and Braclii()].oda. 
Teachers' School of Science. 
The temporary connection with the students of the Normal 
School has been continued this year. The course given by Miss 
J. M. Arms in the laboratory of the Society, and referred to in 
the last annual report, was successfully finished in June, 1894. 
It consisted of lessons of two hours each upon the common tj^jes 
of echinoderms, raollusks, crustaceans, and insects, given with 
special reference to the efiicient teaching of these subjects in 
elementary schools. Miss Arms's great experience and ability in 
this direction are well known, and it is unnecessary to add that 
the lessons were highly appreciated by the oflicers of the 
Normal School and by her pupils. 
A similar course has been given this year in February and 
March, consisting of lessons of two hours each, and has been 
equally successful. Field lessons are also contemplated in con- 
nection with this course to be given when the season is suitable. 
The ladies of the Woman's Education Association were 
appealed to by Miss Dora Williams of the Normal School and 
generously responded, pajdng for the services of the teacher in 
the last series of lessons, the first series having been given 
gratuitously by Miss Arms.
