He made Trees imbibe Spirit of Wine, and other 
Liquors impregnated with Aromaticks, which gave a 
Smell and Tafte to the Stalk, Leaves and Wood ; but 
could not penetrate to the Fruit, by reafon of the 
Finenefs of the Capillary Sap-Vellels near the Fruit, 
which alTimilated to their own Subftance the high- 
tailed and perfum’d Liquors. Spirits kill'd the Trees, 
as far as they were imbib’d ; but fcented Waters did 
not. 
He receiv’d in proper Vellels the Matter perfpir’d 
from Trees which is a tallelefs Water,* but corrupts 
and llinks fooner than common Water. 
He weigh’d three Cubick Feet of the fame fort of 
(Brick-') Earth, taken from the Surface of the Earth 
downwards, in July 17x4, the lightell of which was 
about twice the fpecifick Gravity of Water : Then 
fetting them to dry, found by the lofs of Weight, how 
much Water they contain’d ; the greatell Quantity ex- 
hal’d from a Cubick Foot being lolfe, and the lead,' 
6 ft, 1 1 Ounces. N. B. The Weights he made ufe of were 
Avoirdupoids. 
In order to find the Heat of the external Air in 
Green-Houfes and in Stoves, as alfo the Degrees of 
Hear at feveral Depths in the Earth, and in hot Beds, 
he provided fix Thermometers, whofe Stems were of 
difierent lengths, but adjulled in their mark’d De- 
grees ,* fo that they began at the freezing Point, and 
ended at 90 Degrees, where the Heat was equal to the 
Heat of warm Water, that may be born by the Hand, 
without ftirring it about, which is the middle Point 
between freezing, and the Heat of boiling Water. 
• By thefe Thermometers he obferv’d the Degrees 
of Heat in feveral Cafes to be as follows : Of the Blood 
a 
=64. Of the Human Body =5"4. Milk from the Cow, 
and Heat fit to hatch Eggs =55’. Vrine = 5^8. Tem-
