to his:1077°. Several other trials were made, which gave re- 
fults fo nearly alse that I have: little apprehention of any 
material error. 
From thefe data it is eafy to reduce Shee foate to the ae 
through their whole range ; and from fuch reduction it will 
appear, that an interval of near 480° remains between them, 
which the intermediate thermometer férves as a meafure for; 
that mine includes an extent of about 32000 of FAHRENHFIT’s. 
degrees, or about 54 times as much as'that between the freez- 
ing and boiling points of mercury, by which mercurial ones 
are naturally limited; that if the {cale of mine be produced 
downwards, in the fame manner°as we have fuppofed Fan-. 
RENHEIT’s to be produced upwards, for an ideal ftandard, the — 
freezing point of water would fall nearly on 8° below o of. 
mine, and the freezing -point of mercury a little below 8° ;. 
and that, therefore, of the extent.of now meafurable heat, 
there are about _{,ths of a degree of my {fcale from the freez- 
ing of mercury tothe freezing of water; 8° from the freezing 
of. water to full i ignition 5 and 160° above this to ye nievel 
ae I have hitherto attained. | | 
As we are now enabled to compare not only the higher My. 
grees among themfelves, and the lower among themfelvés, 
upon their refpective feales, but likewife the higher and lower 
with each other in every flage, it may, be proper to take a ge~ 
neral view of the whole range of meafurable heat, as exprefled 
both in Fanrenuerr’s denominations and in mine; and for, 
this purpofe I have drawn up a little table of a few of the prin-. 
cipal points that have been -afcertained, to thew their mutual 
relations or proportions to each other: any other points that. 
have been, or hereafter may be, obferved, by thefe or any 
other known thermometers, may be inferted at pleafure. .
