in sorting and labelling the specimens. These gentlemen have as- 

 sisted the Society while at the same time doing work in the direct 

 line of their own studies. They have also sorted and labelled the 

 collection gathered last summer by the Curator and his party near 

 St. Armands, which are more particularly mentioned farther on in 

 this report. 



A series of the beautiful fossil leaves found in the Dakota group 

 of Ellsworth Co., Kansas, have been obtained by exchange from 

 Prof. F. H. Snow of the University of Kansas. Many of these 

 are new species, and all are types, either published or soon to be 

 published by Professor Lesquei'eux. We have also acquired by 

 purchase a series of fine specimens of the fossil corals from the 

 limestones at the Falls of the Ohio. Both of these lots have been 

 catalogued, mounted, and placed on exhibition by Mr. Henshaw. 

 The Society is indebted to Miss Elizabeth D. Boardman who has 

 done considerable work upon the Curator's collection of Steinheim 

 shells, and when this is finished he will be able to present to the 

 Society a complete series of these valuable fossils. 



We have received a very acceptable gift from Prof. O. C. Marsh, 

 in the cast of the femur of Atlantosaurus, and we are indebted to 

 Sir William Dawson for the donation of several specimens of fossil 

 plants. 



The collections not mentioned remain substantially unchanged 

 since the last report. 



Teachers' School of Science. 



The liberal action of the trustee of the Lowell fund, in defraying 

 the expenses of the lessons and in granting the use of Huntington 

 Hall, has enabled the Society to continue to extend the benefit of 

 the instruction in this school to teachers of neighboring towns as 

 well as to those living in Boston. The agents, who acted in these 

 towns and villages in previous years, continued their kind offices, 

 distributing and receiving applications and also tickets according 

 to the plan of which details were given in the report of 1883. The 

 superintendent of public schools in this city has also kindly as- 

 sisted us by attending to similar technical details in Boston. 



Two courses were given in Huntington Hall under the auspices 

 of Mr. Augustus Lowell. The first consisted of five lessons on
