TO CORRESPONDENTS. 
We have mislaid the cover enclosing a communication from Mr. 
Jobn Reid, and containing his address; this circumstance has pre- 
vented our earlier acknowledgment of its receipt. It appears to us 
that his researches are well contrived, and likely, if pursued, to lead 
to some important information connected with pharmaceutical chemis- 
try ; we therefore thik it prudent to withhold his paper for the pre- 
sent, until we hear from him again. 
_ The specimen from Newry, forwarded by Mr. Bell, is pitchstone. 
F.O.S., from Leadenhall Street, has been received, but we do not 
understand the object of his fetter. 
We are sorry to decline the insertion of the letter signed M.R.1.; 
but its details scarcely come within the objects of this Journal. The 
subject of gas illumination, however, is, as he justly observes, con- 
nected with the “useful applications of science ;” and we regret, in 
common with M.R.L., and the majority of our fellow-parishioners, 
that the improvements in lighting and paving displayed by the sur- 
rounding parishes have hitherto been so obstinately excluded from 
St. George’s. After submitting to the nuisance of laying pipes, and 
the stench of its general introduction, why should we be deprived of 
the only compensation, namely, the advantage of its l¢ght in our streets?
