Equivalents ; by M. Carzy Lexa. 
were these groups natural groups, but that the chemical proper- 
ties of the members of each group corresponded in many cases 
; in 
expressed, from a new source. The author therein shows that 
many of the substances usually classed as elements comport 
themselves in the physical properties exhibited by their combi- 
nations as compound bodies, and that it 1s possible from these 
physical properties to determine (hypothetically) the number of 
“Dhysical” or absolute atoms which he supposes to be contained 
in a chemical atom of such body or pseudo-element, He en- 
deavors to show that it is possible to calculate the spe 
(chemical) atoms in its com ound molecule, as data, but that 
the results lead to the immediate inference that each chemical 
atom contains with few exceptions several physical atoms. , 
For particulars of his theory I must refer to the origina 
paper, but some of his results are as follows: fea aia 
each chemical atom.*
