The Librarian, Dr. N. L. Brirron, exhibited the additions 
received to the Library since the last meeting, and read the full 
list of titles of the same. 
He also announced an interesting discovery of a stone adze, 
found in an excavation at the Moravian Cemetery on Staten 
Island. 
Pror. O. P. HuBBARD made some remarks upon the differ- 
ences in durability of various building-stones, and noted particu- 
larly the permanence of some forms of slate, as shown in old 
graveyards, where slate headstones are very enduring, and retain 
their inscriptions for long periods. 
Dr. NEWBERRY continued the same topic, and spoke of the 
destructive effect upon marbles and limestones of sulphurous 
acid engendered in the combustion of bituminous coal, in cities 
where that material is used for fuel. 
He then gave an outline of the mnost important work done at 
the meeting of the National Academy of Sciences, and at that 
of the Council of the American Geological Society, both held 
during the past week at Washington.
