Description
Autograph Letter Signed, to Mr. Henslow, cancelling the meeting planned to take place in his rooms on Wednesday. 1 page, 7 x 4 inches, with two lines and signature overleaf. Parkstone [Dorset], 13 April 1890. George James Allman (1812 – 1898), Irish ecologist, botanist and zoologist who served as Emeritus Professor of Natural History at Edinburgh University. His most important work was upon the gymnoblast group of the hydrozoa, on which he published in 1871-1872, through the Ray Society, an exhaustive monograph, based largely on his own researches and illustrated with drawings of remarkable excellence from his own hand. Biological science is also indebted to him for several convenient terms which have come into daily use, e.g. endoderm and ectoderm for the two cellular layers of the body-wall in Coelenterata.
