jer various IMPROVEMENTS ad AL-

PRINTING is to be performed thereunth, 
fp as te diminifhb the TROUBLE and EX- 
PENCE of PRINTING, and to render it 
gore UNIFORM and BEAUTIFUL. 
According to this !pecification, the ca- 
“pital letters, with 2 few exceptions, fhould 
be comprized in the compats of an oval, 
by which they wal occupy lefs room than 
ufual, and be more uniform. Each {mall 
Fetter is to be without any tail-p.ece or 
dete: nder j and ai teal of the type, 
uiuelly forming the fhoulder, is to extend 
o lower than the Sady ot the letter ; con- 
Beatty the letters will occupy lefs reom 
in printing without being lefs legible.— 
Tire {mali letters thathave We dds or  afcend- 
Bg points which rife above the body cf 
fhe charaGers, fhould have ther heads 
fhortencd about one-third, which, befides 
uniformity, will allow recom for a greater 
fpace beiween the lines in pristing, or

Rutherdo net appear neceflary, yet. we 
éannot help thinking that his plan of fup- 
prefiing all the de’ cendieg parts of th 
fall letters, would add greatly to tie 
cauty of fine printing ; and it is obvious 
that mo® of the characters already m ule 
might ftill be employed in the bufinefs, 
€onlequently the expence in adopting this 
ravention could not be very greet.

ér SEXTANT, au the PURPOSE of taking 
ALTITUDES of celefital or other OB-

[Aug. 1, 
fo asto obtain a level for the purpofe of 
taking altitudes, either on land or water ; 
which is performed by making a circular 
‘tube or rng of brafs, or other fubftance, 
from two to three inches in diameter, in 
which are fitied four tranfparent glafles, 
directly vd to, and parallel with, 
each other, | o that the furfaces of the fluid 
contained in the tube may be diftinétiy 
feen by the obferver. The infide-of the 
tube may be about a quarter of aa inch 
in diameter, and half full of fome tranf-- 
parent fluid. It is then to be fixed toa 
{mall apparatus, with proper jomts and 
adjufments fo as to bring it to its true po- 
fition on the quadrant. 
The true potition on the infrument be- 
ing obtained, and the ring filled up to the 
center of the glaffe 8; the quadrant or fex- 
tant muft be held im a vertical pofition, 
and the furfiee cf the fluid be brought to 
form a peric&t level with the eye of the 
obferver : then the objeét whote altitude 
is to be taken, is reflected down to thts 
fluid level, in the fame manner as when 
altiiudes are taken by the fea-horizon. 
The: ariificial horizon may be fo con- 
ftru&ed as to be connected with a. tele- 
{cope, fuch as is frequently applied to 
quadrants and fextants; by which means 
eae their con- 
tact with the image of the fun or any other 
body, m may be more exactly determined, 
and the altitude may be read off upon the. 
arc, as in common caies.
