MR. BRODIE ON MYRICIN. 
Melissic Acid. 
Melissin, heated with lime and potash, as the similar experiment was made with 
cerotin*, is, like that body, converted into an acid. This acid has a similar appear- 
ance to the wax acid already described. It has however a much higher melting-point, 
namely, 88°-89° C. The preparation of the substance need not be again described.

the silver salt of the cerotic acid.
