Peabody Academy of Science, SALEM, MASSACHUSETTS. —- 
The herbarium of the Peabody Academy of Science (established in 
1867) originated in the collections received from the Essex Institute 
(established in 1848), a portion of which came from the earlier 
collections of the Essex County Natural History Society (established 
in 1834). When received by the Academy in 1868 the dried plants 
were unmounted, and with them came numerous specimens of woods, 
fruits, gums, etc. The Academy herbarium is intended to be exhaus- 
tive only so far as to cover the flora of Essex County, Massachusetts. 
Some special collections, however, from outside this limit are pre- 
served to illustrate all the orders of plants. The Essex County 
plants received in 1868 numbered about 500 specimens, collected 
chiefly by William Oakes, Rev. J. L. Russell, and George D. 
Phippen. In 1875 an effort was made to develop the herbarium in 
connection with the preparation of the county flora, the specimens 
for this purpose being collected principally by John H. Sears and 
John Robinson. In 1880 Mr. John Robinson published his Flora of 
Essex County, Massachusetts. The herbarium now contains 4420 
specimens of plants belonging to the Essex County flora, and about 
3200 specimens of plants of wider range. Among the latter are 
many specimens distributed by A. H. Curtiss, George Vasey, C. G. 
Pringle, a set of C. F. Austin’s Hefaticae, and Algae collected by 
Mrs. A. L. Davis. 
The collection of Essex County woods, containing upwards of 500 
specimens, consists of cross- and longitudinal-sections together with 
the fruit of the nut- and cone-bearing trees. It includes a set of 
blocks and long sticks of the wood of Essex County trees to which 
the government tests for specific gravity, tensile strength, etc., were 
applied in 1880 and which are described individually in Professor 
Sargent's report in the ninth volume of the publications of the tenth 
census. Mr. John Robinson has the care of this herbarium.

The existing herbarium of this Society, now in charge of Mr. Joseph 
P. Thompson, dates back only to 1866, or since the great fire in the 
city of Portland which destroyed nearly all the collections of the
