It is now a little over twelve months since the investigation and treatment of chronic infective disease was undertaken at this hospital, made possible by the erection of a treatment centre and the appointment of an ear, nose and throat surgeon. From what I have seen of the results obtained during the period under review I am convinced of its therapeutic value, not only in recent cases of psychosis where other forms of treatment have failed, but also in chronic cases, which my clinical experience would have pointed to as hopeless, has amelioration taken place.
