2. Action of Hydrochloric and Hydriodic Acids on Meconin. 
When meconin is treated with hydrochloric or hydriodic acid as above described in 
the case of opianic acid, it is resolved into chloride or iodide of methyl -and a new com- 
pound containing 
c 9 h 8 o 4 . 
The reaction which takes place is 
C 10 H 10 0 4 +H Cl— C 9 h 8 o 4 +c H 3 Cl. 
This substance may be regarded as a monomethylized derivative of a hypothetical 
normal meconine, 
c 8 h 6 o 4 , 
and we therefore propose to name it monomethyl-normal meconin , or shorter, methyl- 
normeconin. 
It gave the following results on analysis : — 
I. 0-4623 grm. gave 1-0152 grm. carbonic acid and 0-1904 grm. water. 
II. 0-4300 grm. gave -9105 grm. carbonic acid and 0-1775 grm. water.

Methyl-normeconin crystallizes without any water of crystallization ; it is soluble 
in cold, but much more so in hot water ; it is easily soluble in alcohol, and slightly so in 
ether. 
With perchloride of iron it behaves exactly in the same manner as methyl-nor-
