fitamp, and are each to contain one grain 
of the mercurial panacea. For the yel- 
Jow Iezenges, take of the mercurial pan- 
acea one pound, of fugar elezen pounds, 
_ of crocus martis halt an ounce; mix with 
water as before, and form isto lozenges, 
of which each mult contain one grai: of 
the mercurial: thefe are to be dried in 
the fun. The method of vfing the medi- 
cines, is to take one or more of the yellow 
lozenges (according to the age of the pa- 
tient) at night, and oce or more of the 
brown in the morning. 
OLfervatious. The compofition of thefe 
lozenges, as /pecified in the patent, is fim- 
ple and efficacious ; but unqueftionably 
contains nothing which has not been in 
common ufe for a century back with every 
medical practitioner. The mercurial pan- 
acea is calomel wafhed with fpirit of 
wine, which in fact is an entirely ufelefs 
operation when the calomel is well pre- 
pared ; and we prefume this term is here 
only ufed, becaufe it is lefs familiar than 
the other. The crocus martis in the yel- 
low lozenges 1s fimply to give the colour, 
in the dofe here employed. Certainly the 
patentee cannot arrogate to himfelf the 
exclufive ufe of calomel, jalap, and white 
fugar, for the removal of worms from the 
human inteftines !

MR. RICKMAN, for @ SIGNAL-TRUMPET. 
This trumpet, made by Mr. RicK- 
MAN, Bookfeller, Upper Marybone Street, 
we believe to be the fame to which a pa- 
tent was granted a year or two ago to 
Mr. FiTZGERALD, the intention of which 
is to enable perfons to produce a very ioud 
report in circumi!ances where cannon 
would be inconvenient, and thus anfwer 
the end of fignal guns. The invention 
is perfe€tly fimple and ingenious, being 
nothing more than affixing a piltol to a 
common fignal-trumpet - inftead of the 
mouth-piece. The :eport thus produced 
equals that of a nine-pounder, as was fa- 
tisfaGtorily proved by experiments made 
at Woolwich. The common fpeaking- 
trumpet, ufed at fea, is employed by the 
patentee ; and the piltol-barrel, as well as 
the common mouth-piece, are made to 
{crew on at pleafure. For a fil! louder 
report, a f{wivel or other {mall piece of 
cannon may be ufed inttead of the piitol, 
and then the trumpet has a parabolic form 
given to it, that it may not fuffer by the 
great concuffion. 
‘The various ufes, both civil and mili- 
tary, to which this invention will apply, 
may be ealily imagined ; but we may ob- 
ferve, that one great ule of the trumpet, 
lately euroiled. (Nov. 1, 
that of fending articulate founds to a 
greater diffance than the mere vorce can 
effect, is here entirely loft; and it be- 
comes merely an alarm fignal, the pur- 
port of which can be only inferred trom 
collateral circumitances.

MR. DENIZE’, for a CEMENT. 
A Parent has been granted to Mr. 
Joun Baptist Denize’ of George 
Street, Portman Square, Chemiit, for a 
cement for various purpoles. 
The inconvenience that often attends 
the ufeé of common mortar, the injury 
which it often receives by moifture, and 
its lofs of cohefion, when not well made, 
has often induced various perfons to fub- 
ftitute materials of a lefs alterable nature, 
which do not require fo much attention in 
the preparation. Any fubitance of an oily 
nature, rendered thick by the addition of 
fome unalterable earthy or vitreous mat- 
ter, has often been ufed for this purpofe ; 
and of this kind is the cement propofed by 
the patentee. The bafis is petroleum in 
any form, in which a fmall portion of 
fuiphur is diffolved by melting, and to 
this is added any kind of vitrefcent earthy 
matter whatever, fuch as clinkers and {co- 
riz from iron or glafs furnaces, puzzo- 
lane, or any volcanic afhes, and the like. 
Thefe are to be reduced to powder and 
ftirred into the melted fulpbur-oil till it 
becomes of fuch a confiltence as to be 
readily {pread with a trowel, and does net 
{tick to the fingers when coo]. A cement 
of this kind is firm, durable, and imper- 
vious to moifture. |

MR. GOULD, for @ SEA-LOG. 
A Patent has been granted to Mr. 
CHesTER GOULD, of the county of One- 
ida, New York, Merchant, for an inftrn- 
ment or log for afcertaining a fhip’s dif- 
tance at fea. 
The machine wfed by the patentee isa 
cylinder of brafs or other material not in- 
jured by falt water, of about three inches 
and a half in diameter, and nine or ten in- 
ches in length. To one end of the cylin- 
der a head-piece of brafs wire is {crewed 
in order to detain any fea-weed or other 
floating fubftances which might get within 
and interrupt the working of the machi- 
nery. This latter is compofed of a fly 
whcel revolving on its axis and fet within 
the infide of the cylinder fo as to prefent 
itfelf endways to the water, and takes its 
motion from the oblique or angular pofi- 
tion of the vanes like a common windmill 
or fmoak jack. AJl the accuracy of the 
inftsument depends eflentially upon the ex- 
actne&&
