386 BIOGRAPHICAL SKETCHES. 
this society, the anatomical part by Professor Wyman. Two 
other papers of that early year, on the anatomy of two Mol- 
lusea, Tebennophorus Carolinensis and Glandina truncata, 
published in the fourth volume of the society’s Journal, each 
with a copper plate, are noteworthy, as showing that he pos- 
sessed from the first that happy faculty of clear, terse, and 
closely relevant exposition, and that skill and neatness of illus- 
tration with his pencil, which characterize all his work, both 
of research and instruction. 
Another paper of that year, “On the microscopic structure 
of the teeth of the Lepidostei, and their analogies with those 
of the Labyrinthodonts,” read to this society in August, and 
published in Silliman’s Journal in October, 1843, was impor- 
tant and timely. In it he demonstrated that the Labyrinthine 
structure of the teeth, considered at the time to be peculiar to 
certain sauroid reptiles, equally belong to gar-fishes, and con- 
sequently that many fossil teeth which had been referred by 
the evidence of this character alone to a group of reptiles 
founded upon this peculiarity, might as well belong to ancient 
sauroid fishes. ' 
Although not of any importance now to remember, I may 
here mention his report to this society on the Hydrachos 
Sillimani of Koch, a factitious Saurian of huge length, suc- 
cessfully exhibited in New York and elsewhere under high 
auspices, and I think also in Germany, but which Dr. Wyman 
exposed at sight, showing that it was made up of an indefinite 
number of various cetaceous vertebra, belonging to many in- 
dividuals, which (as was afterward ascertained) were collected 
from several localities. 
But the memoir by which Professor Wyman assured his 
position among the higher comparative anatomists was that 
communicated to and published by this society in the summer 
of 1847, in which the Gorilla was first named and introduced 
to the scientific world, and the distinctive structure and affini- 
ties of the animal so thoroughly made out from the study of 
the skeleton, that there was, as the great English anatomist 
remarked, “ very little left to add, and nothing to correct.”
