The Commissioners in Lunacy have lately recommended the erection of detached hospitals for the treatment of infectious disease at most of the English County Asylums, and it would seem that at least twenty of these institutions are already equipped in this matter. These hospitals differ greatly as to size, form of construction, adjuncts, distance from the main building, and, in fact, in all their features. Some resemble villas rather than hospitals, others are attached by corridors to the asylum. The most of them are of one story only, but one or two are of two stories. Some are divided into blocks, others are in one continuous building. The causes of this endless variety are, firstly, that there are no model plans of asylum hospitals published, and, as far as I am aware, no plans published at all, if I except that lately built at the East Riding Asylum, described in this Journal for April, 1887; and, secondly, that these hospitals being for the most part small affairs, architects are rarely invited to send in plans, so that there is a total absence of the stimulus of competition.
