8IK B. C. BRODIE ON THE CALCULITS OF CHEMICAIi OPEEATIO^fS. 



It appears, therefore, that so far as any information extends which is afforded to us by 

 the specific heat of silver, the symbol of this metal may be regarded as identical in form 

 with that of zinc or mercury, the equation under consideration being expressed thus, 



or as being similar to the equation which expresses the relation existing between mer- 

 curous chloride and its elements, 



Or again, it may also be regarded as identical in form with the symbols of chlorine and 

 of nitrogen ; in which case the above equation is thus expressed, 



and is similar to the equation which connects the symbols of the chloride of iodine with 

 those of chlorine and iodine. 



And, lastly, the facts are not even inconsistent with the assumption that the symbol of 

 silver is identical in form with the symbols of oxygen and sulphur, so that 



which is similar to the equation which connects the symbol of the bisulphide of chlorine 

 with the symbols of its elements 



The symbols of silver and its compounds appear, on the two more probable hypotheses, 

 as follows : 



Hypothesis I. W=A, X=2ari.
