210 DR T. ANDERSON ON SOME OF THE 
Chloropianyl as obtained by either of these processes is in the form of transpa- 
rent colourless needles, scarcely soluble in cold water, rather more so in boiling. 
Alcohol and ether dissolve it much more abundantly, and deposit it in fine crystals. 
It is not more soluble in the alkalies than in water, and they do not remove chlorine 
from it. Nitric acid dissolves it with a red colour, and on heating it is decom- 
posed. It is soluble in cold oil of vitriol, and on heating, a fine greenish-blue 
solution is obtained, from which water throws down brown flocks, soluble in the 
alkalies with a red colour. Chloropianyl melts at 347°, and sublimes unchanged 
at a higher temperature. The properties of specimens prepared from opianyl and 
from meconine extracted directly from opium, were compared, and found to be 
perfectly identical. Of the following analyses, the first two were made with 
chloropianyl obtained from meconine in the dry way, and the third was from 
opianyl, and prepared in the wet way.

This corresponds with the formula C,, H, Cl O,. 
The action of chlorine upon meconine has been examined by CovrrsE, but 
his results differ entirely from those just described, and his statements are very 
loose, unsatisfactory, and in some points absolutely conflicting. He passed chlo- 
rine into fused meconine, and obtained a product containing 25°75 per cent. of 
chlorine, and consisting of crystals mixed with a resinous matter. The greater 
part of the chlorine exists in the latter, the former containing only 5°48 per cent., 
which is removed by oxide of silver, or by potash. The product is said to crys- 
tallize from alcohol in short prisms, to contain no chlorine, but to have a power- 
fully acid reaction, and to precipitate the salts of lead and copper. CourRBE de- 
signates it mechloic acid, and assigns to it the formula C,, H, O,,, which ob- 
viously bears no relation to that of the original substance, and is in itself impro-
