    NOTES ON SOME OF TOE f I ^ OF *' ^ FHY 'SKTIANI Oi* t CHEMICAL REACTIONS OF MORPHIA. BY T. G WORMLEY, M.D. Pure morphia was dissolved in water by the aid of just sufficient sulphuric acid, and a small drop of a saturated solution of the re- agent was applied to a grain of the morphia solution, placed on a glass slide. The amount of morphia operated upon will frequently be stated in the form of a fraction, it being understood to imply the fractional part of a grain of morphia, in one grain of water. 1. Nitric Acid. «r. t • x truth* grain of morphia in one grain of water, when acted upon by one drop of concentrated nitric acid, almost immediately as- sumes a lemon color, which in a few seconds changes to orange, and finally into a fine red-prange, which very slowly becomes yellow. 2 the mixture is very soon of a lemon color, changing to a good red-orange. Tooth, soon lemon color, which in a few minutes changes to light and then to deep orange. roToth, very slowly assumes a lemon color, after some min- utes a very light orange. ttVirtfi> only a perceptible lemon color after some minutes, very faint and only to be seen upon a white ground.
