makes it necessary to bring the latter in as small a compass
as possible

If the Sea itself is not to be the refrigeratory, you must then
have a cistern for that purpose: w Qu. which must be supplied
by a pump from the Sea,

Qu. whether instead of having the cistern to inclose the
worm as in the common distilling apparatus, it might not
be better to have it suspended placed above the worm, and
not connected with it:? In th but als contrived so as to let
the water drop upon the worm? In this case the worm
might be success coated externally with [woollen] rags, to
retain the dropping water, and the refrigerator would be formed
not by application of a body of fluid, so much as by the act of evaporation.

What you have to do then, seems to be to set about experimenting
which you may do without the time piece as well as with, in
order to determine this problem.

The heat of the atmosphere (which must be any degree from
the hig lowest to the highest that has ever been known) the degree
heat of the focus, The area of that surface (of the fluid) to which the heat is first applied
(i:e: the lower surface of the fluid from whence the bubbles begin
to rise) and the area of the upper surface, of the f being given, to
find that bulk and shape of the refrigerating apparatus, that
shall be least cumbersome [most compact] so as to answer the purpose: that
is, that shall acquire least momentum by the agitations of
the ship so as to bear upon the common fulcrum of the
whole machine that is kept suspended.

N.B. In this view that apparatus (time piece refrigeratory &c
and all together) seems to be the in point of form the most

Did I tell you what Poore told me, that nice Astronomers observed that the Sun shining upon their Quadrants
&c. plaid the deuce with the divisions? However our time keeper itself will bid defiance to the Sun — but then the
refrigerating water must be kept shaded from it. For in the Sunshine the heat is sometimes as high as 120 which
I believe is about the heat of boiling Aether.
