Sorry folks,

Some of the symbols used did not translate well from my original.
The micron symbol translated as mm and some people received an arrette
instead of the square root symbol.

The sentence;
>>Particularly in view of the fact that Fox used 16mm thick sections of
fresh rat kidney, whereas Helander used 4 mm cubes of fresh rat liver.

Should read " Fox used 16 micrometer thick sections"
quite a difference!
