:
Sulfonal is in the form of colorless prisms, odorless and taste-
less. It is easily soluble in hot water and in alcohol, and but
slightly soluble in 100 parts of cold water, and is soluble in 18 to
20 parts of hot water, and melts at 258° F. ; it is also soluble in
alcohol and ether ; it is not affected by any of the ordinary acids.
It appears to possess hypnotic properties of considerable power,
and is regarded as prompt and reliable, producing a quiet, natural
sleep, lasting a number of hours. It appears to have no unfavor-
able effects on the heart or the circulation, nor on the tempera-
ture, the pulse or the respiration, and to produce no disagreeable
secondary symptoms, nor to interfere with the process of diges-
tion.
It is best administered in hot liquids, such as a bowl of soup or
broth, a cup of milk, tea, coffee, cocoa, in capsules, or in acacia
mucilage, etc.
