The formula therefore of the hydrated acid is Cb.oH6o04. 

 This acid I call Melissic Acid. 



Chlor-Melal. 



By the action of chlorine on melissinea perfectly analogous 

 result is obtained to that obtained by the action of chlorine on 

 cerotine. 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.

I. 0'6663 grm. gave 1-4821 grm. of chloride of silver equi- 

 valent to 0*3665 grm. of chlorine. 



II. 0*6075 grm. gave 1*341 grm. of chloride of silver equi- 

 valent to 0*3316 grm. of chlorine. 



III. 0-6475 grm. gave 1-4375 grm. of chloride of silver 

 equivalent to 0*3555 grm. of chlorine.
