ing spiders and myriopods, 2434, from Worcester County ; ` 
crustacea, II species, 3 from Worcester County; mollusks 
(represented by shells), 1500 species, 4000 specimens, 33 from 
Worcester County. Echinoderms and corals are well repre- 
sented, and the lower forms by a collection of microscopic 
slides. 
From the vegetable kingdom, pressed specimens (Worcester 
County, except some of the algæ), there are: Seed plants, 600 
species ; ferns, club mosses, etc., 40; mosses and liverworts, 
148; fungi, 34; algæ, 137 (almost wholly marine); diatoms 
(slides), few. 
The inorganic kingdom is well represented by about 2000 
specimens ; rocks and minerals from all parts of the world, 
among them being the representative rocks of central and 
southern Worcester County, and 57 species of minerals from 
the county. 
This material, plainly labeled, is arranged in upright and 
horizontal cases and drawers in the rooms of the society build- 
ing, at the corner of State and Harvard streets. The museum 
is open to the public without charge six days in the week, and 
is visited by about 6000 people yearly. There is an intelligent 
custodian in charge, ready to be helpful in every possible way 
to visitors. 
Special displays are made from time to time upon the tables 
in the larger rooms. For instance, during the early part of last 
winter a display of the coniferæ of Worcester County was 
made, consisting of sprays of the foliage of each species, with 
the cones. Later were shown the winter birds of Worcester 
County — permanent and transient — first the hawk group, 
_ then the smaller birds, and finally the game and water birds. 
Two or three weeks are allowed for such exhibits, and at the same : 
time articles are published in the daily papers describing them. 
During the past summer and fall the flowers and fruits of the 
county, as they made their appearance, were brought in and 
shown, marked with their common and scientific names. 
The work is also educational, and the society encourages the 
use of its material by all interested in any branch of natural 
history. Its rooms are supplied with tables where one may
