6 ANNIVERSARY ADDRESS. 
with a tail and pointed ears, and probably a climber of trees. 
Nay, he traced back the chain of descent until he found, as the 
progenitor of all the vertebrate animals, some aquatic creature, 
hermaphrodite, provided with gills, and with brain, heart, and 
other organs imperfectly developed. The treatise concludes by 
remarking what are the hopes which the advance of the human 
race in past ages seems fairly to justify. He says: “We are not, 
however, concerned with hopes or fears, but only with the truth 
as far as our reason allows us to discover it.” “I have given the 
evidence to the best of my ability ; and we must acknowledge, as 
it seems to me, that man, with all his noble qualities—with 
sympathy, which feels for the most debased—with benevolence, 
which extends not only to other men, but to the humblest living 
creature—with his god-like intellect, which has penetrated into 
the movements and constitution of the solar system—with all those 
exalted powers, man still bears in his bodily frame the indelible 
stamp of his lowly origin.” 
After the publication of his first great work, Darwin continued 
to gather evidence tending to strengthen his theory. In 1862 he 
published his remarkable work on “ Fertilization of Orchids,” and 
in 1867 his “Domesticated Animals and Qultivated Plants.” In 
1872 Mr. Darwin published “The Expression of the Emotions in 
Man and Animals”; in 1875, “ Insectivorous Plants”; in 1876, 
“Cross and Self-fertilization in the Vegetable Kingdom”; and in 
1877, “ Different forms of Flowers in Plants of the same Species.” 
Only last year appeared his work upon Earthworms, in which he 
traced the operations of worms in gradually covering the surface 
of the globe with a layer of mould, and showed the wonders pro- 
duced by the operations of these insignificant creatures. 
Mr. Darwin, having inherited a good private fortune, engaged 
in no business or profession, but devoted his whole life to natural 
Science. And here I may mention how it came about that he
