oxides, in which the oxygen of the acid to the oxygen of the base is 
as 4 to I. 
M. Peligot has endeavoured, without success, to form an analogous 
acid by means of chlorine; the action is very violent, and inflamma- 
tion and complete destruction of the salt ensues. This happens with 
bromine if placed in contact with the salt in a fluid state ; it must be 
acted on by passing the vapour of bromine slowly into it, which will 
be absorbed. The action of iodine differs from that of bromine, for 
it forms both iodide and iodate of silver; but the acid has not yet 
been sufficiently examined to determine its nature. 
The action of bromine on benzoate of silver is moreover not a par- 
ticular action caused by the nature of benzoic acid, for it acts in a 
similar manner on salts formed by acids which appear to be less dis- 
posed to superoxygenation, as the oxalic and acetic acids, and every- 
thing tends to the belief that the mode of action of this body will be- 
come general.— L’ Institut, 15 Fev. 1836. 
OBSERVATIONS ON THE SOLAR ECLIPSE OF MAY 15, 1836. 
Photometrical Observations during the Eclipse, by Thos. Galloway, Esq. 
To R. Taylor, Esq. 
Dear Sir, 
The following observations, made during the solar eclipse on the 
15th instant with two of Leslie’s photometers, may be interesting to 
some of yourreaders. The observations were made at Mr. Bishop’s 
observatory in the Regent’s Park, and the photometers were placed 
on a table on the lawn, fully exposed to the sun’s influence. With 
the exception of a few passing clouds the sky remained clear till to- 
wards the end of the eclipse, when the atmosphere became hazy.
