On account of the ascent of heated fluids, let bodies be placed
at greater elevation in proportion to their temperatures: The
coldest beingin the lowest situation & the rest in strata forming a gradualsufficiently
extensive range of temperature, in successive gradation.

N.B. Water must not be used in temper.res between 32o& 40o
as it contracts instead of expanding by heat. Blagden.

2. Interposition of NonSlow Conductors of heat.

i. Materials

ex. gr. Wool or Cotton (raw.) hair -straw, hay, (chopped?)
(qu. proper degree of compression of wool are?)

Ashes, Charcoal, Wood — Glass.

(N.B. In Scotland coals retained for a night almost at the heat of ignition by
being surround buried in ashes.)

ii. Disposition: In concentric shells: for lateral communication of
heat by the motion of heated air favours the communication of heat
as much as its ascent.

3. Surface diminished as much as possible.
