PHILADELPHIA ACADEMY OF NATURAL Sciences, March 3.— 
Mr. Meehan called attention to.a specimen of Cypripedium insigne 
which had developed two flowers instead of the usual one, and was 
thus on the way toward a spicate inflorescence. The upper three- 
lobed petal had also become one-lobed, and the labellum in the 
upper flower was only twice instead of three times, the length of 
the column. Mr. Meehan considered such changes as nature's 
efforts to establish new forms. 
Dr. Leidy had recently received from Floridaremains of a species 
of Rhinoceros, including the crown of the last upper molar. The 
latter indicated a species not before described. which he proposed 
` to name Rhinocerus proterus, The speaker expressed his belief 
that Dinoceras Marsh, was equivalent with -Uintatherium Leidy. 
Mr. A. H. Smith gave an account of a boring on Black’s island, 
below Fort Mifflin, Delaware river. The boring passed through 
the following deposits. Alluvial mud seventy-five feet; dark gravel, 
six feet; white tenacious clay, two feet; beach-sand forty-seven 
feet; gravel, two feet, and then again beach-sand. : 
Professor Heilprin thought that, in the light of this boring, the 
beach-sand might be cretaceous. The same speaker then read a 
continuation of his paper on disputed geological and palzonto- 
logical points. 
March 10.—Dr. Leidy exhibited the upper molar tooth of a 
Hippotherium, belonging to an animal of about half the size of 
the horse. The example was from Florida, and in the same col- 
lection with it were some fossil crocodile bones, and the end of 
the phalanx of an extinct llama or camel, probably indicating new 
species. : 
Professor Heilprin stated that he had made a careful micro- 
scopic examination of the sand from the boring below Fort 
Mifflin, but had found no traces of Foraminifera. The roundness 
. of the grains might indicate sea-sand.
