[May 1, 
Lafresnaye types have been catalogued and relabelled with special 
type labels by Mr. Cory who has also generously defrayed the extra 
expense of the necessary clerical work. 
Mr. Robert Ridgway has returned the collection of skins of 
neotropical birds, having identified and labelled them. 
New England vertebrates. 
A list of all vertebrates known to occur in New England with 
annotations concerning such as are in the collection has been com- 
piled by Mr. Henshaw. 
Mr. Cory has given us some birds, and a few mammals have been 
added by purchase. 
Teachers’ School of Science. 
The liberal action of the Trustee of the Lowell fund in defraying 
the expenses of the lessons and also in granting the use of Hunt- 
ington Hall has enabled the Society to continue its efforts to ex- 
tend the benefit of the instruction in this school to teachers in all 
the neighboring towns as well as to those living in Boston. The 
agents who acted in the adjoining towns and villages last year con- 
tinued their kind offices, distributing and receiving applications and 
also tickets according to the plan which was described in a former 
report. The Superintendent of Public Schools in this city has also 
kindly assisted us by attending to similar technical details in Bos- 
ton. 
Prof. W. O. Crosby has given a course of ten lessons during the 
past winter upon the geology of Boston and vicinity. The primary 
object of the lessons was to acquaint the teachers of Boston and 
vicinity with the natural opportunities for geological study by which 
they are surrounded and especially to show them how to use these 
opportunities for their own culture and the benefit of their pupils. 
The subject was treated in accordance with the following 
scheme : — 
1 . A general study of the physical features of the Boston basin 
and of the geological changes now in progress in this region. 
2. A systematic study of the various minerals and rocks found 
in the Boston basin together with the more characteristic kinds of 
structure which they exhibit. 
3. A summary of the geological history of the district so far as 
that is plainly recorded in the rocks.
