Dr. Thomas Deighton. 
Now Deighton is running his own show. T. B. Wood has died and 
Capstick is very seriously ill and I believe never comes to the 
laboratory. Consequently Deighton is running around laying most 
emphasis upon problems of an economic nature. The most unfortunate 
thing is that Deighton has no adverse critic. Since my last visit 
here he had been empowered by the authorities to take a trip to the 
Continent and I found that he had visited Fingerling, Mj^llgaard, and 
Lefèvre, and I am not sure about Zurich and Berlin. He had had no 
experience in indirect calorimetry but had made this visit to 
European laboratories and presented a very confidential report to the 
British Ministry, including a rather harsh criticism of Lefèvre, and 
he was most chagrined to think that the British Ministry permitted 
Lefèvre to see a copy of this. He tried to get a copy for me but 
the successor to T. B. Woods, F. W. H. Marshall, whom I had not met 
personally, told Deighton that I could not have it. At present he 
was distressed by the fact that the Minister of Agriculture had lost 
interest or had "let down" in appropriations. 
In a recent article Deighton had touched upon a theory of Rubner 
on the question of length of life, death, and the potentialities of 
life, much upon the basis that a man or animal had only a certain time 
to live anyway and that with excessive activity he would be burned up 
more quickly. This is interesting in connection with work proposed by 
the Nutrition Laboratory in 1955 on Professor Sherman's rats. 
Deighton is still obsessed with the idea of direct calorimetry 
and he had made experiments on the cat. He is at present constructing 
a compensation chamber for poultry, in which he is using cellophane 
walls, their particular value being, according to him, that the poultry 
will live normally in light. (See figures 7 7 > 7$> and 7?*) The 
apparatus had also an elaborate electrical heating system and temperature 
measuring system to maintain the walls at constant temperature. It 
seemed to me rather hopeless. Although he had direct calorimetric 
compensation chambers he wishes now to add the indirect to it. He felt 
that 24-hour periods were necessary for poultry, but he also admitted 
that poultry experiments were made primarily for political reasons, to 
keep the interest of their farmer constituents.
