A short account of the proceedings in a case of lunacy in the State of Colorado may not be without interest and value to the readers of this Journal, as there has been some agitation in England for the establishment of a similar form of procedure. As each State makes its own laws in the matter, they vary in every State of the American Union. In Colorado the procedure for committing a lunatic consists, briefly, in trial by jury before a judge or what we should call in England a stipendiary magistrate, and precisely resembles the proceedings of a criminal trial in England.
