LOWELL FREE COURSES. 
An exhibition of water-color sketches of Flowering 
Plants will be given in the class-room of the Society from 
May gth to May i^th, inclusive. These drawings were made 
from nature by Miss Helen Sharp , and have been used in part 
in the botanical classes of the Lowell Free Courses of the 
Teachers' School of Science, but it is considered desirable 
to exhibit the collection as a whole. 
This collection includes sketches of about seven hun- 
dred species, a number of them being illustrated by two 
or more drawings to show fruit as well as flower. They 
are arranged in accordance with the classiflcation in Gray's 
Manual and are of especial interest in studying plants 
comparatively : For example, the sketches include seventeen 
species of Violets, thirteen of Buttercups, a complete set of 
New England Trilliums and Cypripediums. These with 
other well represented genera afford ready means of dis- 
tinguishing species. 
The exhibition will fae open daily between 12 and 4.30 o'c!ock on the dates 
above specified. AIl interested are invited to attend. No tickets are issued. The 
entrance to the Class-room is by the basement door on Boylston Street.
