Because of this, a heptazine-based structure similar to Liebig's melon, a compound initially prepared around the same time that the pharoah's snake reaction was discovered, was not ruled out by the authors as a partial component of the solid material. [10] The generalized reaction is as follows: 2 Hg(SCN) 2 → 2 β−HgS + CS 2 + C 3 N 4

It is known that some focusing and sharpening of the image occurs in the lateral descending trigeminal tract, and it is ...
