2o. Indirect, on the Hydrometer principle 106 f.67 vers0 (b)
Rising in proportion as the fluid in which it is
immersed contracts & sinking as it expands.
The expansion of the glass or other materials
must be deducted as it will counteract the force
with which the motions will
with which these motions will be be performed.
Scale marked in the Stem.
They will be less sensible and accurate than common
themometers; but vastly less expensive.
Qu - fluid? Distilled water. -oil-solution of salt?
Mercury.
Qu. would it be better to add weights to a small cap
at the top?

3. Saturation - Quantity of salts dissolved by water, known by sp.c gravity
as Sulphate of soda, &c.
Quantity of water dissoleved by air. Vide Dr Hutton's experimets.
Proportional quantities of acid & alkali in Carbonate of Ammonia
Vid. Davy's Exper.ts
4. Decomposition.
N.B. Thermometers placed at top of liq.ds are cooling at bottom of those heating
for average temperature at middle.
Means of inspecting the thermometer by a pane of glass opposite
to where it is placed, & a door or by thermometers projecting.
Qu. Means of transferring the expansion:
a horizontal tube
