KIRWANIAN SOCIETY OF DUBLIN. 
Dec. 1, 1813. A paper “On the crystallographical Method 
of Haiiy,” by Dr. J. O. Reardon, was read. 
In this paper a concise statement of the theory of the learned 
Abbé was given, and also of the principal arguments brought for- 
ward in its, support. The objections that have been offered to the 
system by various philosophers, as well as the replies of the Abbé, 
were then noticed: and a number of observations were made on 
the validity of the former, and the adequacy of the latter. 
March 23, 1814. A paper “On an extensive Bed of Mag- 
nesian Limestone, found in the vicinity of Dublin,” by S. Witter, 
Esq. was read. 
An account of the analysis and of some peculiar circumstances 
attending the calcination of the stone, was first given. 36 per 
cent. of carbonate of magnesia were found in combination with 
51 of carbonate of lime; the remaining portion being made up 
by silex, oxides of iron, and manganese. After some geological 
observations, the paper concluded with some remarks on the ap- 
plication of the mineral to the purposes of practical husbandry. 
The same gentleman likewise read a series of observations, 
_ with an account of some experiments relating to the formation 
and properties of iodine. In allusion to the question of its ele- 
mentary nature, he referred to some striking similarities in certain 
well known compounds.
