T. Wayland Vaughan, Ph.D.: ‘‘Rate of Growth 
of Stony Corals,’’ illustrated with lantern slides. 
Henry A. Pilsbry, Se.D.: ‘‘On the Tropical Ele- 
ment in the Molluscan Fauna of Florida.’’ 
The session closed with illustrations by 
means of a superb collection of lantern 
views, of methods of bird photography by 
William L. Baily. 
In the evening a reception was tendered 
the delegates by Dr. Dixon, Mrs. Dixon 
and Miss Dixon in the Bellevue-Stratford 
Hotel. In common with everything else on 
the program it was brilliantly successful. 
The weather Thursday morning was a 
violent and most undesirable change from 
that of the day before, a fall of snow being 
driven along by penetrating winds. It 
was a most gratifying evidence of the 
earnestness and interest of those attending 
the sessions that little falling off in the 
attendance was observable when Dr. Dixon 
called the meeting to order a few minutes 
after ten. 
He opened the proceedings by referring 
to the death of Dr. Montgomery, who had 
been placed first on the program of that 
session. His place was taken by Edwin J. 
Houston, Ph.D., who made an interesting 
communication on ‘‘How the Natural 
Sciences can be made Attractive to the 
Young.”’ 
In continuation the following papers 
were read: 
James A. G. Rehn: ‘‘The Orthopteran Inhabit- 
ants of the Sonoran Creosote Bush.’’ 
Merkel H. Jacobs, Ph.D.: ‘‘ Physiological Char- 
acters of Species.’’ 
Henry F. Osborn, LL.D.: ‘‘Tetraplasy, or Law 
of the Four Inseparable Factors.’’ 
George Howard Parker, Se.D.: ‘‘Sensory Appro- 
priation as Illustrated by the Organs of Taste in 
Vertebrates. ’’ 
John M. Macfarlane, Se.D.: ‘‘The Relation of 
Protoplasm to its Environment.’’ 
William H. Dall, A.M., Se.D.: ‘‘Mollusk Fauna 
of Northwest America.’’ 
The time having arrived for luncheon, 
SCIENCE 
[N.S. Vou. XXXV. No. 901 
two papers were deferred to an afternoon 
session not provided for on the printed 
program. 
On reassembling at 2 o’clock, Henry G. 
Bryant, LL.B., read a paper on ‘‘Govern- 
mental Agencies in the Advancement of 
Geographical Knowledge in the United 
States,’’ and the scientific sessions con- 
eluded with a superbly illustrated and 
most interesting lecture by Witmer Stone, 
A.M., the ornithological curator of the 
academy, on the “‘Fauna and Flora of the 
New Jersey Pine Barrens.’’ The com- 
munication was specially enjoyed by those 
from a distance as imparting in a most 
pleasing manner information regarding a 
region of quite unusual physiographical 
interest. 
The rest of the afternoon was devoted to 
a demonstration of the resources of the 
museum and library, including a fine dis- 
play of one hundred and thirty-two micro- 
scopes and an exhibition of a portion of the 
academy’s superb collection of butterflies. 
In the evening one hundred and sixty 
members and guests sat down to a banquet 
in the exquisitely decorated new geological 
hall, formerly occupied by the library. 
The occasion will long be remembered as a 
specially enjoyable one by those present. 
Dr. Edwin G. Conklin, professor of biol- 
ogy in Princeton University and one of the 
vice-presidents of the academy, was an in- 
imitable toastmaster and at his call appre- 
ciative speeches were made by the mayor, 
who sat on the right of the president; 
Mons. Jean de Pulligny, director of the 
commission of French engineers to the 
United States; Dr. Henry Fairfield Osborn, 
president of the American Museum of Nat- 
ural History, New York; Dr. Dixon; Dr. 
Theodore N. Gill, of the Smithsonian Insti- 
tution; Dr. William J. Holland, of the Car- 
negie Museum of Pittsburgh, and Dr. 
Nolan, all bearing testimony to the acad-
