communication. I must confess an inability at that time to conceive 
that a radio transmitter would a few years later be curing Dementia 
Paralytics. 
Electro-magnetic induction was tried by Neymann, Osborne and 
Holmquest in 1928. Those who have seen this type of treatment will 
confess that it savours of the miraculous. The heating element is a loop 
or coil resting on the blankets. The following is the description of a 
technique used by Guy P. U. Prior, and recorded in the Year Book of 
Neurology, 1937 : — 
‘ ‘ The patient is insulated against loss of heat by use of terry cloth, 
a rubber sheet and six blankets which are wrapped around him and 
around which 3 turns of the cable are laid. The patient is given a hot 
bath, an enema, 10 ozs. of hot milk or coffee and 6 grains of Sodium 
Heberal two hours before treatment. Pulse, respiration and temperature 
are recorded every 15 minutes and a hot drink consisting of glucose 
10 per cent in Saline solution 0-6 per cent, is given freely. The 
temperature must be kept about 103-4° F. for 8 hours and during 2 of 
these hours it is between 105-2° and 106° F.” 
As a result of such modern methods, the patient suffering from 
General Paralysis has now a positive prospect of arrest of the disease. 
This improves in ratio to the time from onset of symptoms. The early 
treatment produces the best results. Such considerations have a 
significance to-day. 
COMING SHADOWS. 
We are used to those financial taxes which are an inevitable 
concomitant to the war effort. We may fail to remember those invisible 
taxes which burden the national health. War produces a bounteous 
crop of syphilitics from which wdll follow a future harvest of general 
paralytics. 
In 5, 10, 15, or 20 years, we may expect to see cases which illustrate- 
the classic train of symptoms. Let us hope that our prophylaxis will 
be as perfect as possible, that our heat therapy so ably commenced will 
improve through the years. We may find that every syphilitic should 
receive heat therapy in order to sterilise that nidus of brain infection 
which, lying dormant for a decade, can awake, we know not why, to 
virulent activity and produce those deadly results to which I have 
referred. 
It is not surprising that efforts have been made to utilize the 
converse effects of cold therapy. Patients have been placed under 
conditions of extreme cold for Jong periods. Whilst good results 
have been claimed, the dangers of pneumonia and other complications 
have militated against success. 
SHOCK TREATMENT. 
Twenty years ago in the wards of every psychiatric hospital, in the 
outpatients of every psychiatric clinic and indeed in every doctor’s 
consulting room were cases in which the treatment was of the “By God 
and by Guess variety,” a compound of hope, time, aperients, fresh air 
and drugs. One would see —
