ANNALS OF THE ACADEMY Wh 
The fourth President of the Academy, Professor O. C. Marsh, 
who had held that office since 1883, declined re-election in 1895, 
and the Academy passed the following resolution unanimously: 
“That the thanks of the Academy be tendered to the retiring 
president for the zeal and ability with which he has admin- 
istered in succession the offices of vice-president and president 
of the Academy during a period of seventeen years.” Pro- 
fessor Marsh was succeeded by Professor Wolcott Gibbs who 
held the office of President until April, 1900, when he resigned. 
He was succeeded in rgo1 by Dr. Alexander Agassiz. 
In this same year, 1895, which we have been considering, the 
Academy expressed its gratification at the completion, under 
the direction of two of its members, of extensive publications 
calculated to be of great benefit to science and to the people. 
These were the reports on the geology of Pennsylvania and the 
catalogue of the library of the Surgeon-General’s Office. The 
resolution was as follows: 
“ Whereas, since 1874, Prof. J. P. Lesley, as the director of the second 
geological survey of Pennsylvania, has, with the cooperation of a band of assist- 
ants, published 127 octavo volumes of reports, which will remain a monument of 
his scientific and literary activity: 
“ Resolved, That the National Academy of Sciences, at a session held in Phila- 
delphia on the 30th of October, 1895, while expressing their regret at the absence 
of their fellow-member, J. P. Lesley, wish at the same time to congratulate him on 
the successful completion of his reports on the geological survey of Pennsylvania, 
and further to express their appreciation of the services he has rendered to science 
in devoting his life to the interest of the survey, a task to which he has brought 
an unsurpassed knowledge of the geology of the State. 
“2. The Academy congratulate their fellow-member, Dr. John S. Billings, on 
the completion of his Catalogue of the Army Medical Library, and on the issue of 
the final sixteenth volume of this unequaled gift to the medical scholars of the 
world.” 75 
In 1896, when a bill was pending in the Senate calling for the 
restriction of experiments on the lower animals in the District 
of Columbia (Senate no. 1552), a letter was addressed to Sen- 
ator Jacob H. Gallinger by the Chief of the Bureau of Animal
