Annual Meeting.] 232 [May 6, 



Paleontology. 



Miss Martin, under the direction of Mr. Henshaw, has finished 

 the cleaning and remounting of the American collections. 



Mollusca. 



Mr. Henshaw spent double time on this collection last year, and, 

 therefore, devoted his whole time to other collections this year. 



Sponges. 



Mr. Henshaw, assisted by Miss Martin, has completed the 

 mounting of the exhibited collection and has labelled about one-half 

 of the collection not on exhibition. The Curator has identified the 

 larger part of the New England calcareous sponges and some of 

 the Silicea. 



Crustacea. 



The mounting and cataloguing of the general collection has been 

 finished by Miss Martin, under the direction of Mr. Henshaw. 



Insects. 



The biological material in cases Nos. 4-12 of Room L has been 

 worked over by Mr. Henshaw, catalogued and mounted. 



The general collection of tfymenoptera and Hemiptera have 

 been brought together and partly worked out ; of the Hymenoptera 

 we have 350 species identified and of the Hemiptera 250 species. 



Teachers' School of Science. 



The liberality of the Trustees of the Lowell Fund in defraying 

 the expenses of the lessons and also in continuing to grant the use 

 of Huntington Hall has enabled the Society to persevere in its 

 efforts to extend the usefulness of this department. 



At the request of the Superintendent of Public Schools, Mr. 

 Lowell employed the Curator to give a course of ten lessons. 

 The work was directed mainly to the subjects which had been 

 prescribed in the " Observation Lessons" of the Primary, and the 

 " Elementary Science Lessons" of the Grammar Schools^ of Bos- 

 ton, and the instruction dealt with as many types of the animal 

 kingdom as could be advantageously studied, with specimens in 

 hand, during the time allotted to the course.
