MR. BAILY’S DESCRIPTION OF A NEW BAROMETER. 
having been extended to every tenth of an inch in the height of the mercury, and to 
every fifth part of a degree of its temperature, are now printed in his Jakrbuch for 1837- 
It is by these latter tables that the monthly means, in the Meteorological Register, are 
now corrected for temperature. 
As I am not aware that any tables of this kind have been printed in England, I shall 
(with the approbation and consent of the author) give, on this page, some of the 
values here mentioned : namely, for every half inch in the height of the mercury 
from 28‘0 to 30 - 5 inches, and for every degree of its temperature from 30° to 90°, 
which will be found very useful and convenient for the correction of such barometers 
as are furnished with a continuous brass scale*. 
Corrections for a Mercurial Barometer with a continuous Brass scale : all subtractive.

* By a continuous brass scale, I mean one that extends the whole length of the tube : and it should be spe- 
cially borne in mind that the tables, here alluded to, apply only to barometers of that construction. For baro- 
meters of the ordinary construction, other tables, computed also by Professor Schumacher, will be mentioned 
in the sequel. See the note in page 437.
