membranes with their veffels are conti- 
nued into the futures, to form the fecreto- 
ry organ by which the bones are extended. 
It accounts alfo for an appearance of 
blood-veffels pafling through the futures, 
becaufe the increafe of blood goes to this 
fecretory organ for the purpofe of the ex- 
tenfion of the bones. 
The above explanation accounts like-

MR. JOSEPH HUDDART’S, (HIGHBURY;) 
jor Improvements in the Manufafure 
of large Cables, and Cordage in geue- 
ral. 
HE improvements defcribed in this 
fpecification have for their cbjeét the 
laying of cables and cordage by means of 
machinery, which confifts of an axis, to 
the top of which is a gudgeon with holes 
for the ftrands to pafs through. There 
are aifo circular planes or tables fixed to 
the axis and connected together by pil- 
lars, and fpole-frames, of which as many 
are to be ufed as there are ftrands in the 
cable. The axis revolves within a dead 
or fixed wheel, the teeth of which are con- 
nected with the counter-wheels upon the 
circular plane or table, and thefe again 
with the fpole-frame wheels. The ftrands 
being prepared, are to be wound on reels: 
friction blocks or clutches are connected 
with the axis of each reel to regulate the 
terfion of the ftrand when drawn from the 
reel. From the reel in each fpole-plane 
the ftrand paffes through a guide, to dire&t 
it into the plane of the groove. The 
counter-wheels are to give the fpoles, with 
the firands, a contrary motion to that of 
the axis, which will thereby produce a re- 
lative motion between the plane or table 
and the {poles. Other means are contriv- 
ed, fo that equal quantities of the ftrand 
will be delivered in every revolution from 
each fpole. 
An adequate idea of this invention can- 
not well be cbtained without a reference 
to the drawings which accompany the fpe- 
cification, 
‘© IT do not allege (fays the patentee,) 
that any fingle thing reprefented in the 
drawing is in itfelf new, or that the parti- 
cular combination of any part or parts 
with other parts is new, fuppofing the 
faine to be f-parately taken and confider- 
ed. But what I lay claim to as my in- 
Vention is, the ultimate combination of 
fenger or rope is winding 
thefe feveral parts, as forming one entite 
machine or fytem of machinery, tending 
to the laying of c-bles and cordage in a 
manner that is fo all fubftantial and eflen- 
tial purpofes new. 
MR. T. J. PLUCKNETT, (DEPTFORD,} 
Soran Addilicn and Improvement to Cap= 
fans and Windlaffes for Ships, and other 
Purpofes. 
Mr. Piucknett’s improvements apply 
to the furging or forcing up the meflenger 
or rope going round the capftan, and the 
fleeting over, or forcing over, the cable dr 
rope going round the windlafs ; and alfa 
to the holding-on, or hauling-off, the mef- 
fenger or rope going round the capftan or 
windlafs. ‘The firft improvement is in- 
tended to facilitate the winding on and 
off the meflenger or rope, or to avoid the 
neceffity of forcing it up by beating it up 
with a maul, or other inftruments, or 
by flackening it, which is often attended 
with danger, and always with lofs of time. 
This isdone by means of lifters, or {mall 
pieces of iron, about two inches fquare, 
and from twelve to eighteen inches long. 
Thefe lifters are carried ronnd with the 
capftan, and are worked on a circular 
wheel or rim in a groove in the deck, on 
the principle of an inclined plane. By the 
lifters travelling round as the capftan 
turns, the head of them rifes under the 
meffenger or rope, and thus gradually 
forces it up, fo as to let in, or make room 
for, the fucceeding turn of the rope to 
come upon the capftan without a poffibi- 
lity of its ever riding or coming over the 
former turns. The heop forming the in- 
clined plane may be made moveable, and 
thicker at one part of the circle, only gras 
dually defeending to the oppofite part, 
and in that cafe it muft be fo fhitted round, 
that the loweit part of the plane may be 
at that part of the capftan where the mef-
