MR. WILLIAM-WARRIS’S (SHEFFIELD), 
Sor an Improvement in the Mounting of 
Opera-Glafis. 
This invention confits in making the 
mounting of opera-clafles to occupy the 
leaft, or “nearly the leaf, poffible {pace to 
which they are capable of being reduced, 
which is perfo: aned by: bringing the tops 
or heads of the tubes, (ities or draws, 
to au horizontal plane or level furface, or 
nearly fo; fo that the fame number of 
tubes, fprings, or draws, may be con- 
tained within the fpace of the exterior 
cafe: 
To mount a glafs to occuipy the leaf 
poflible {pace, Mr. Warris makes a 
groove or cavity in the head of each tube, 
&c. fufficiently deep to receive the next 
within it, the interior tube or head: having 
a ring or other contrivance within its ca- 
vity, by which the tube may be drawn 
out. But as it willbe found equally con- 
venient, and lefs expenlive, that the head 
of the firft-or interior tube firould project

opera-glafs, exhibiting the manner in

By this method all the tubes may ut

as in thofe of the common conftruétion, 
the wideft draw is as much fhorter than 
the fmallefi, as the conjoint thicknels of 
the Libs heads, being nearly one-third 
partof the opera-glafs. Fram the form

Rone ats ye for fundry Toals, Tin-

Coats. 
The boring-apparatus confifts a6 two 
fpring psles fixed, to which is attached, 
by two chains, a red of iron or other me- 
tal in joints, fecured to each other by 
{crews or otherwife, fo that the faid rod 
may be lengthened or fhertened in the 
ufual manner, and of fundry bits-or teols

extremity of the faid ted, each fingly 
contrived for penetrating that particular 
fpecies of foil beft to which it tsadapted, 
and’ of feveral auxiliary ‘implerhents for 
extracting the foil from the hole formed 
by the faid bores, and for otherwife aliitt-

‘The boring inftroment having that bit 
fixed to it which is bet fuited to the foil 
it is intended to penetrate, and being fuf-

pended to the fpring polcs, is to be put. y 
into motion by a handle fa#ened to it at 
right: angles. The ule of the two {pring- 
poles is to keep the rod fteady to the aa 
pendicular line of the hole, which a fingle 
one could not do, as its motion mult 
performed fo as to form arcs of a circle

As the foil to be bored is of various
