Dear Father

I couldn’t catch Garrod² last night. He cannot give a definite answer without thinking over it. He thinks that in the quick beating of the heart in fear, it is not doing any more work— He cannot say even that it is actually working harder in hard exercise— Its seems to be rather complicated & not to easy to say what working harder means— He thinks that running & feeling the pulse wouldn’t prove anything.—³
