The Struggle for Life in the Fndividual 
and Community. 
By Puitie B. Mason, M.R.C.S., F.L.S., F.Z.S., &c. 
(Presidential Address delivered November 30th, 1894.) 
T the foundation of all modern ideas as to organized 
AL. beings, not only in their structural peculiarities and 
mutual interdependence, but also in their faculties and social 
relations, since mind is inseparable in this world from the 
existence of the body, lies the work of Charles Darwin. 
Either consciously or unconsciously ; for his theories have so 
permeated not only all minds, but also the phrases of scientific 
and philosophical expression, that all writings on these sub- 
jects necessarily show the impress of his genius, even when 
the object of the argument is actually to oppose his deductions. 
His first publication on these subjects was made in the year 
1859, and was contained in a modest octavo volume of less 
than 600 pages. Its Title page was as follows: “On the 
Origin of Species by means of Natural Selection; or, the 
Preservation of Favoured Races in the Struggle for Life.” 
I propose in this paper to shortly consider some of the 
results on individuals of the same species of the Struggle for 
Life, but before doing so, I must define what I mean by this 
phrase, show how the necessity for the struggle arises at all, 
and finally explain how the favoured races are preserved by 
means of Natural Selection.
