monthly meeting of this society was held on Wednesday evening, December 14, 
1881, in the Patents Room of the Literary and Philosophical Society. Dr. 
Ellis occupied the chair. There was a good attendance of members. Two 
auditors, Messrs. Gillespie and Harkus, were appointed, and one new member 
elected. Dr. May readapaper on “ Bone under various aspects,” showing the 
beginning (so far as has been ascertained) from embryonic stage, to maturity 
and ultimate destruction, of which the following is an abstract : — He said — I 
have culled a few facts from the anatomical works of Erasmus Wilson, Gray, 
and the Physiological writing of Dr. Kirkes, at present edited by W. Morrant 
Baker. Some facts also that have come under my own observation I have 
ventured to mix up with the well-attested and world-known writings of those 
eminent men which I have collected from these sources, and with the few speci- 
mens of old and young bones I hope I shall not be tedious. The subject matter 
is very important and very voluminous, too much so for one evening’s reading, 
nevertheless I shall venture to ask your kind indulgence, and hope it may 
induce other members to come forward with papers and make our meetings 
more useful and instructive. Bone is composed of one-third animal matter, 
which is almost completely reducible to gelatine by boiling, and two-thirds 
of earthy and alkaline substances. In these proportions :

It strikes one as an essential that the framework on which is built the human 
form divine, should be sufficiently strong with a certain amount of elasticity to
