of a fquare, at equal diftances from each 
‘other. To each lamp belongs an opake 
~ cover or blind, with proper apparatus, to 
move. backwards and forwards, fo asto 
exclude the light, and only fo many of the 
lamps be left vilible, as are neeeflary to re- 
prefent the letter of the alphabet, or other 
fign intended to be exhibited. Mr. Boaz 
is very particular in his fpecification, to 
defcribe a valt variety of mechanical me- 
thods by which the effect of his contri- 
vancemay beproduced. Although hehas 
pitched upon 25 lamps, as an{wering to the 
number of letters in the alphabet, yet he 
obferves that nine lamps, properly fitted 
up with blinds, fliders, pullies, incliners, 
&c. would produce nearly the fame effect ; 
and a fimilar effect might be obtained by 
a greater or fmaller number of lamps than 
25, fo that he wishes it to be diftinétly un-. 
derftood that it js not inthe number o€ 
lamps made ufe of, nor in the particular 
configuration or conftruction of the ma- 
chine, that the invention confifts, but in be- 
ing able to reprefent by means of lamps, or 
luminous bodies, a8 candles or phofphorus, 
or by means of opaque fubitances the fig- 
nals defired.

afcertain to whom the honor of inventing

‘Robert Hooke, in a paper read before the 
Royal Society, onthe 21ftof May, 1682, 
enters very particularly and at large into 
the methods of “ difcourfing at a diftance, 
not by found but by fight.””” In connec- 
tion with the patent before us, ane paf- 
fage of this paper is fo ftriking, that we 
cannot forbear tranfcribing it. “* And 
thofe mutt be either day characters or night 
characters, if they be made ufe of in the 
day time, they may be all made of deals, 
and of a bigne{sconvenient for the feveral 
diftances. . Any one of the charaéters 
may fignify any one letter of the al-- 
phabet, and the whole alphabet may 
be varied 10,000 ways; fo that none 
but ’the two extreme corre{pondents 
fhall be able to difcover the informatien 
conveyed. If the charaéters are for the 
night, then they may be made with inks 
or other lights, difpofed in a certain order, 
whieh may be covered and uncovered, ac- 
cording to the method agreed on.+” 
In1794, M. Edelerantz, Councellor of 
Chancery, at Stockholm, defcribed a te- 
legraph forday and night, the fignals in 
the night time were made by lamps covered 
and uncovered 2s was found neceflary.

EULOGY on THE LATE DUKE or 
BEDFORD sy THEHON. CHARLES 
. JAMES FOX. 
We abftain from giving place to a detailed 
Biographical Account of the late Duke of 
Bedford till our next ; but, for the prefent 
Number, we have obtained a correct report 
of the Subftance of the Speech of the Hon, 
_C. J. Fox, delivered in the Houfe of Com- 
mons, on moving the writ for Taviftock, 
and we publifh it under the immediate 
fanction of that Gentleman. 
7 F the fad event which has recently oc- 
curred were only a private misfortune, 
however heavy, I fhould feel the impro-— 
priety of obtruding upon the Houfe the 
feelings of private friendfhip, and would 
have fought fome other cpportunity of ex- 
. preffing thofe fentiments of gratitude and 
aficStion, which muft be ever due from me 
-_ to the memory of the excellent perfon, 
whole lofs gives occafion to the fort of 
i 
7 
motion of courfe, which I am about te 
make to the Houle. It is becaufe I con- 
fider the death of the Duke of Bedford as 
a great public calamity, becaufe the Pub- 
lic itfelf feems fo to confider it; becaufe, 
not inthis town enly, but in every part of 
the Kingdom, the impveffion made by it 
feems to be the ftrongeft, and moft uni- 
verfal, that ever appeared upon the lofs of 
a fubjeét; it is for thefe reafons that I pre-. 
fume to hope for the indulgence of the 
Houle, if I deviate, in fome degree, from 
the common courfe, and introduce my mo- 
tion in a manner which I mutt confefs to 
be unufual on fimilar occafions. At the 
fame time, I tru, Sur, that I fhall not be 
fulpected of any intention to abule the in- 
dulgence which I afk by dwelling, with 
the fondnefs of friendthip, upon the va- 
rious excellencies of the chara&ter to 
which I have alluded, much lefs by en- 
tering into a hiftory of the feveral events 
of his life, which might ferve to iJluftrate
