lature, to enable us to grapple with and eradicate it from all in¬ 
fected herds. The discoveries of such eminent investigators as 
Pasteur and Koch has evolved from obscurity the essential cause 
of the disease, and has placed in our hands the means to diagnose 
the malady in all its stages of development, and its complete 
disposal has only to be intrusted to capable and conservative 
men to insure success. To Charles Darwin, the credit is due of 
having firmly established by an immense amount of evidence 
the scientific explanation of the most important factor in evolu¬ 
tion ; that every day fresh discoveries and experiments confirm 
the great principle of the adaptation of the individual to its ex¬ 
ternal surroundings ; and it has almost passed into the same 
phase as Newton’s law of gravity, as a fundamental law accepted 
by all men of science as the basis of modern thought, to which 
all philosophies necessarily conform. [IrwelL] The commodi¬ 
ous building in which we meet to-night has been evolved from 
its inorganic corner-stone, until even the blind have been made 
to see its fair proportions and enjoy its blessings. More than a 
century ago Ben Franklin ‘‘ held the key ” that has since un¬ 
locked the mysterious power of electricity that furnishes the 
matchless light by which I read, while the marvellous discovery 
of the ‘‘ Rontgen rays ” may possibly revert to some modest 
maiden, who first drew the shadow of her lover upon the garden 
wall. 
In closing, I wish again to thank your committee for the 
assignment of this evening to address myself to a body of men 
who have been relieving the sufferings and prolonging the lives 
of their fellow-men ever since the time when the “shepherds 
tended their flocks by night,” and that wondrous proclamation 
went forth “ peace on earth, good will to all mankind.”
