Ir is stated in the British Medical Journal that the 
Ontario Legislature has established a research chair 
for Dr. Banting, the originator of the idea that diabetes 
might be controlled by extracts of the islands of

suggested by Sir Edward Schafer a good many years 
ago, and under which it has now become a commercial 
product. The income of the chair, to which Dr. Best

Tue first attempt to broadcast a picture by wireless 
telephony was made on May 24 at the London 
Station of the British Broadcasting Co. The experi- 
ment was made by Dr. Fournier d’Albe, who used a 
special code method adapted to a juvenile audience 
of “ listeners-in.”’ It being Empire Day, the picture 
chosen for broadcasting was a portrait of King 
George V. The picture was coded by dividing it into 
thirty horizontal strips and splitting up each strip 
into twenty squares. A letter was assigned to each 
square to indicate its average shading, and these 
letters were written out in thirty lines of twenty 
letters each. Each line was divided into four groups 
of five letters, and each group was dictated into the 
microphone in turn. The lines were numbered, so 
that mistakes could be easily avoided. The total 
time of transmission, with instructions, was twenty- 
two minutes, but it was found that the code message 
itself could be taken down in eight minutes. The 
picture was reproduced either by graduated dots on 
Squared paper or on an ordinary typewriter, using 
letters of graduated size and making the line space 
equal to the letter space. Recognisable reproduc- 
tions were made in from twenty to twenty-five 
minutes. In the complete method a special type- 
writer or ‘‘ dot-writer ’’ is to be employed.
