To Wittiam Goopman, of Coventry, 
' Hatier ; for certain. Improvements in 
Looms. >. 
‘Mr. Goodman’s ingenious invention 
of certaiimprovements, apply to’ that 
description of looms usually employed 
for the.‘weaying of narrow articles 
(commonly called Dutch engine-looms) 
and consists principally in a novel 
arrangement of the shuttles and slays 
in the-batten. The construction of the 
battén, with the slays and the shuttles, 
aré’in: every respect the same as 
usually’ employcd in engine-looms, 
except, that in this improved loom, 
there are three shuttle-boards, forming 
two distinct races for the reception of 
two sets of shuttles; the warp, or slay- 
Spaces of the upper range intervening 
between the spaces of the lower range. 
Mr. G: only claims, as his own inyen- 
gion, the new arrangement of the shut- 
tles and the slays as connected with 
the batten, and the suspending of the 
knotted parts of the leashes on one set 
of shafts, to arrange with the same.—

PROCEEDINGS OF PUBLIC SOCIETIBS. 
= ; 
ROYAL SOCIETY. 
'T affords us much satisfaction at 
. being enabled to lay before the pub- 
lie a series of curious experiments made 
by a gentleman not it seems of the 
society, but first promulgated at one of 
its meetingsin April last. They relate to 
the ‘condensation of several gases into 
liquids,» by Mr. Farapay, chemical 
assistant in the Royal Institution, and. 
were communicated by the President. 
' Sulphurous Acid.— Mercury and con- 
cenirated sulphuric acid were sealed 
up in a bent tabe, and, being brought 
to’ ‘one end, heat was earefully applied, 
whilst the other end was preserved cool 
by wet bibulous’ paper. © Sulphurous 
acid gas was produced where the heat 
acted,:and was condensed by the sul- 
phurie avid above; bat, when the latter 
had) become saturated; the sulphurous 
acid passed to the cold end of the tube, 
and twas condensed into a liquid. When 
the whole tube was cold, if the sulphu- 
rous acid were returned on to the mix- 
ture of ‘sulphuric acid and sulphate of 
mercury, a portion was re-absorbed, 
bat the jrest. remained on it ‘without 
mixingwy: > >) : 
Liquid sulphurous‘acid is very limpid 
and colourless, and highly fluid. Its, 
refractive power, obtained by comparing, 
it in water and othér media, with water 
contained ‘in a similar tabe, appeared. 
fo be nearly equal to that of water. It 
does rot solidity or Lecome adhesive at 
a temperatare of 0° F. Whena tube 
containing it was opened, the contents: 
did not rash out as with explosion, but 
a portion of the liquid evaporated ra- 
pidly, cooling another portion so much 
as to leave it in the fluid state at com-~ 
mon barometric pressure, It was how-. 
ever rapidly dissipated, not producing, 
visible fumes. but producing the odour, 
of pure sulphurous acid, and leaving the. 
tube quite dry. A portion of the ahd 
of the fluid received over a mercurial 
ped into the fluid insfantly made'it boil, 
from the heat communicated by it. 
To prove in an unexceptionable man- 
ner that the fluid was pure sulpburous. 
acid, some sulphurous acid gas was. 
carefully prepared over ineveuby anit" 
lung tnbe perfectly dry, and’ closed ‘at. 
one end, being exliausted,was filled with, 
it; more sulpburous ‘acid ‘was ‘then 
thrown fy by a condensing syringe, til
