Amides.—When an acid radical replaces any part of the typical hydrogen of ammonia, the resulting compound is called an amide. As some of the amides play a very important part in the animal economy, it is necessary to study their constitution a little more closely. For this purpose it will be convenient to write the formulse of a few important acids in a form which is a slight variation of that previously used.
