SIR, 
, PUNCTUAL peruser of your widely-cir- 
culated miscellany, earnestly solicits of the 
correspondents who combine to fill its inter- 
esting pages, a satisfactory communication 
on the subject of encased phosphorus, pre- 
pared for instant use in procuring flame as a 
substitute for the common tinder-box. I had 
purchased one of the usual make, the light 
from which was to be obtatned by suddenly im- 
merging a common match ; but upon the first 
trial, though done with care, the phosphorus 
became instantaneously ignited, and the ope- 
rator was severely scalded. 
He shall be obliged to any philosophical 
gentleman who will not contemptuously 
smile at his query, but briefly inform him 
_of the most portable and prudent construc- 
tion of these light-procurers, and the best 
method of extinguishing the fame, and 
healing the burn, of phosphorus.

SIR, 
T is frequently asserted, that the body of 
dissenting clergymen in London, as well 
as the corporation of London, and the two 
Universities, enjoy the right of presenting 
addresses to his majesty in person. As I 
have not heard of the exercise of this right, 
I should be very glad to learn from any of 
- your correspondents, whether it exists ; 
and if it does, how it. originated, and when 
it was acted upon. Kn, ¥3

STR, 
HAavinc been lately engaged in trans- 
lating a French work, wherein the term 
Canards tigrés is mentioned, and not knowing 
to what species of the dack the word tigres 
refers, I shall feel obliged 3fsome one of your 
correspondents, conversant in natural history 
and French literature, will inform me, through 
the medium of your magazine. 
_ The letter of your correspondent from 
Bristol, signed E. T..1. of last month, page 
134, refers, I presume, toa letter of mine in 
your Magazine for December last, page 461, 
concerning the aceticacid. Now, sir, 1 by no 
‘means desire to make your valuable magazine 
a vehicle for controversy ; what I have there 
stated, is in the power of any of your readers 
to prove, without having recourse to any 
theory whatever. I must however take the 
liberty to remark, that the acetic acid is, in 
many respects, more agreeable, not to say

more efficacious, for the purposes mentioned 
in my letter, than the process which he re= 
commends. 
Simplicity ia undertakings upon a large 
scale is, at all times, most desirable; andin 
those for the purposes of general health, is 
most peculiarly so. It would have been as 
well if your correspondent had affixed his reat 
name to his letter; we should then have had 
an opportunity of judging how far he was in- 
fluenced in his remarks, by a soreness of feel- 
ing on some other subjects to which I have 
occasionally adverted. | 
Anonymous remarks are hardly fair upon 
those who fearlessly avow their sentiments 
and their names. 
Unawed by the letter of E. T.1., 1 take 
the libe:ty of communicating another fact, 
not indeed of as much tonsequence as acetic 
acid may be: but it is, at any rate, singular; 
and such as perhaps few of your chemical 
readers have had an opportunity of witness- 
ing. Itis, that having occasion to try some 
experiments upon blood, in order to the 
making of Prussian blue, seventeen years 
ago, I put by about four cunces of dried ox 
blood in a dry place, not having immediate. 
occasion for it; and this same blood I now 
have completely dry and unaltered.

SIR, 
‘ 
About twenty years ago F subscribed for 
a print to be engraved after the picture 
of the Siege and Relief of Gibraltar. Two 
guineas were paid to Copley the painter, and 
two more were to be paid on delivery. 
The print has never appeared ; nor has ar 
apology been given, that I ever heard of. 
Before 1 make any remarks on this dise 
graceful transaction, permit me, sir, through 
the medium of your valuable publication, 
to request any information on the subject, 
which you, or any of your very numerous 
friends, can give me: particularly whether 
any explanation, or apology, has been pub- 
licly given; or whether the subscribers have 
still grounds on which to found their ex- 
pectations of the print being delivered, or 
not. ALPHA,

SIR, ; 
SHOULD te glad to be informed by some 
of your legal readers, whether the clause 
in what is called the new police act, au-- 
thorising the apprehension of reputed thieves, 
can be enforced by the city magistrates. The 
very serious depredations that have recently 
been committed in the city by pickpockets, 
render every precaution absolutely necessary.
