There is a fairly general opinion amongst those engaged in asylum work that the classical type of general paralysis is less frequently met with relatively than formerly. This may be due partly to an increased number of so-called atypical cases, and possibly also to cases now being diagnosed as general paralysis, either ante or post mortem, which were not formerly looked upon as such. With a view to finding out the frequency of the chief phenomena of the disease as it is now met with in asylum practice, the following data, both pathological and clinical, have been compiled. The cases examined were (1) all the male cases admitted to the West Riding Asylum, Wakefield, from January 1st, 1896, to December 31st, 1902; (2) all the male cases admitted to the London County Asylum, Horton, Epsom, from its opening in the early part of 1902 to March 31st, 1905; and (3) all the female deaths at Horton.
