ABSTRACT OF REPORT ON THE TEACHERS’ SCHOOL OF SCIENCE, 
BY PROF. G. H. BARTON, CURATOR OF THE SCHOOL. . 
During the year the usual Held and laboratory courses have been 
given. 
The field courses in botany, under the charge of Mr. Hollis 
Webster, were especially devoted to a study of the bryophytes and 
the pteridophytes. The average attendance during the spring les¬ 
sons was 31, and during the autumn lessons, 30. 
The field work in zoology, under Mr. A. P. Morse, was directed 
largely to observation of the animals studied in the winter,— crusta¬ 
ceans and insects. The average attendance at the spring lessons 
was 30, and at the autumn lessons, 16. 
The course in field geology is not a Lowell course, but is sup¬ 
ported by a friend of the School. It is given by the Curator of the 
School with the aid of one or two competent assistants. The 
lessons this year were devoted mostly to a study of the lithological 
character of the rocks near Boston in continuation of the laboratory 
work of the preceding winter. The average attendance at the 
spring lessons was about 47, and in the autumn, 42. 
The laboratory course in botany, given by Mr. Hollis Webster 
with the assistance of Miss J. F. Conant, was directed to a study of 
the flowering plants, and was supplemented by lectures on the life 
history and morphology of gymnosperms and angiosperms. The 
average attendance for the term was about 40. This year’s work 
finishes the four years’ course and about twenty diplomas will be 
granted. 
The laboratory work in zoology was devoted this year to a special 
study of insects. This course is given by Mr. A. P. Morse with the 
assistance of Miss M. E. Cherrington. The average attendance was 
about 32. 
The laboratory course in geology is given by the Curator of the 
School. Two classes are now for the first time carried on. The ad¬ 
vanced class took up dynamical and structural geology and showed 
an average attendance of about 72. Eight of the pupils, having fin¬ 
ished the four years’ course, will receive diplomas this year. The 
beginners’ class took up the subject of mineralogy. The average 
attendance was about 59, and the final examination was taken by 32.
