The formula therefore of the hydrated acid is Cgg Hgg O 4 . This acid I call Melissic 
Acid. 
Chlor-Melal. 
By the action of chlorine on melissin a perfectly analogous result is obtained to 
that obtained by the action of chlorine on cerotin. The substance undergoes also a 
similar change in appearance, being converted into a resin. 
The substance was prepared and analysed with a view to confirming the formula 
of the body.

As in the case of the cerotin, by the action of chlorine two equivalents of hydrogen 
are removed without replacement by chlorine, while the further action is an action 
of substitution, the substance being the analogue of chloral.
