4o. Preservation of Uniformity & Steadiness of
Temperature
Uniformity preserved in fluids (with exception before mentioned)
applying heat at the topbottom & cold at the bottom top.
or else by machanical agitation.
Steadiness within a certain range by a successive gradation of
temperattures as before explained.- But this will require the perfect
steadiness of the two extreme point: with respect to of the lowermost we have
a sufficiently perfect means of obtaining it by ice. The highest
may be obtained by making the supply of heat from a lamp
for instance precisely equivalentequal to the expendditure: which might
easily be done after a few trials, were it not that the exxpendditure
viz, (depending of the lower temperature of the air) is variable.
this however might also be adjusted by repeated trials.
