lxxxiv Charles Stewart. 
for 1907 is upon “The Membranous Labyrinth of certain Sharks,” and 
Prof. Stewart also contributed to the ‘Quarterly Journal of Microscopical 
Science’ some notes upon the teeth of Ornithorhynehus and to the Zoological 
Society some details in the anatomy of the poisonous hzard Heloderma, 
especially relating to the glands which secrete the poison. In addition to 
these papers upon Echinodermata and vertebrated animals, Prof. Stewart 
published a few memoirs upon Corals and other Invertebrates. In all he 
wrote about twenty papers. 
In reviewing Stewart's contributions to scientific literature, the 
“Cataloeues” of the Royai College of Surgeons are by no means to be 
omitted. These recent Catalogues differ in their form and in many other 
particulars from the older Catalogues published during the tenure of the 
Conservatorship of the Hunterian Museum by Sir Richard Owen. The 
volumes are of smaller size, are illustrated by illustrations in the text (with 
an occasional Plate), and are most of them at any rate almost of the nature 
of treatises on the subjects with which they deal. 
Stewart was not merely the editor of the Catalogue, in itself a large piece 
of scientific work, but wrote a great part of it, especially of the first volume. 
Although hardly able himself to devote much time to the preparation of 
scientific memoirs, Stewart was exceedingly generous to others and anxious to 
assist them with the abundant material at his command. Of this the 
present writer can speak from his own experience. Stewart's enthusiasm for 
zoological anatomy was, in fact, perfectly disinterested. A total absence of 
even the capacity for sordid scheming, and a disposition which was, as 
a contemporary justly remarked of him, “unassuming to a fault,’ rendered 
Charles Stewart an ideal official and endeared him to those who were 
privileged with his friendship.
