Geo. B. Emerson, author of the great work upon the Trees and 
Shrubs of the State; Dr. Martin Gay, an able chemist; Dr. 
Chas. T. Jackson, well known as an accomplished chemist, 
mineralogist and geologist; Mr. Francis Alger, the author of a 
valuable work on mineralogy; the Rev. Dr. T. W. P. Green- 
wood, who seemed more divine than human in the loveliness 
of his character; Dr. T. W. Harris, author of the Report on 
Insects injurious to Vegetation, and last to mention, though 
by no means the least in his influence upon the affairs of the 
Society and its character, Dr. J. B. 8. Jackson, whose loss 
we now deplore. 
The particular investigations of Dr. Jackson were gener- 
ally not of a nature to bring him prominently before the 
Society as an instructor in any branch of Natural History, 
his labors being largely confined to a class of subjects more 
generally interesting to students in pathology. Yet the 
Journal of the Society presents to us several papers of great 
value to naturalists, and the Proceedings contain remarks 
made by him at various times embodying much useful in- 
formation. 
Dr. Jackson was elected a member in the autumn of 1831, 
the Society having been incorporated the previous February. 
In 1837 he read before the Society a paper which was 
published in the Journal, giving an anatomical description of 
the Gallopagos Tortoise, which was a valuable contribution. 
In 1842 the Journal gives an account read by him of the 
dissection of two adult dromedaries, male and female. 
In 1845 there is in the Journal a paper upon the dissec- 
tion of a spermaveti whale and three other Cetaceans. 
Of his remarks made from time to time upon scientific 
subjects and published in the Proceedings of the Society, 
may be found some of interesting character upon the teeth 
of Delphinus globiceps, upon fossil bones of the MWastodon 
giganteus from Schooley’s Mountain, N. J., and upon bones — 
from Indian tumuli. 
As said before, Dr. Jackson’s most important work was in
