quently longer exposure at the springs’ vent to the’ atmospheric 
influence. These springs, known as the “ Boiling Springs,” 
doubtless arise from below the impervious beds of clay, which may 
be seen outcropping along the sides of the gulches in the neighbor- 
kood ‘washed out by freshets. While it seems unlikely that they issue 
from such a depth as sixty or eighty feet, which is assigned by 
Guyot.as the limits of the zone of invariable temperature at our 
latitude, it is quite certain that points of origin are deep seated and 
almost, if not entirely, removed from superficial influence. The 
observation of Mr. W. T. Davis upon the Summer temperature of the 
€love Valley springs corroborates this. He found that to be from 
53° to 54°; almost identical with the Winter temperature of these 
opines at the coldest period of the season. The water flowing with 
is elevated temperature nourished an abundant growth of the 
common fresh water alga (Conferva vulgaris Rab.), which in turn 
supported in its thick and confused clusters numerous diatoms and 
infusoria.. The green stems of a species of Veronica, too immature 
for determination, flourished abundantly in the tepid rivulet escap- 
ing from the tiny pools, while within a few feet last Summer's 
grasses were frozen in a crust of ice. | 
> Mr. Wm. T. Davis read a portion of a letter from Mr. Aug. R. 
Grote. The extract is as follows: In 1856 I found Clematis 
ochroleuca growing on Kellett’s Hill, near Egbertville, on the 
Southern slope near the top. My specimens went to the late Hon. 
Geo. W. Clinton, botanist, of Albany. I also collected a specimen 
of the fork-tailed flycatcher, Milvulus tyrannus, near our farm o 
Hill Park, towards the south-west side of the Island. 
ı March 10th.—Mr. Arthur Hollick read the following notes, 
illustrated by drawings and dried specimens :— 
l During the Autumn of 1881 a species of sedge was found in 
company with Callitriche verna and Dichelyma capillaceum growing 
on.the bottom of one of the springs near the present site of the S. 
I. Water Supply Co. It was proliferous, and showed no signs of. 
either perfect flower or fruit, but as it was rather late in the season 
a more favorable time was awaited in which to collect and study it. 
spring was deep, with walled sides and a clean sandy bottom 
and was never known to freeze, even in the severest winter. The 
ap was entirely aquatic—no part of it ever growing to the sur- 
ace of the water. During the succeeding year it was visited from 
time to time in the hopes of obtaining either the flower or fruit, 
but without success. Specimens were however collected with 
aborted proliferous spikes, and it was finally admitted provisionally by 
Dr. Britton and myself into the Flora of Richmond county, in the 
appendix for 1883-84, under the name Heleocharis prolifera Torr (?). 
_ Smee then it has been kept under constant scrutiny, but has never 
been found with flowers, and we were forced to conclude that it did-
