Professor Starling 
Professor Starling was good enough to allow Mr. Higgins and 
myself to spend several hours in his laboratory while he was carrying 
out an experiment. I saw there a part of a unit respiration appa¬ 
ratus for use with animals and was able to give him some suggestions 
with regard to it. At this time he told me that the results of an 
investigation published by Knowlton and himself a short time ago 
would have to be retracted as they found them incorrect. 
I was particularly interested in watching an assistant read off 
a stop watch and report the time of the flow of blood as 5.1, 5.3, and 
5.6 seconds. I noticed that Professor Starling wrote these down. 
On asking the assistant how he got these values, he said that he used 
the stop watch and estimated to within one tenth of a second; if the 
pointer stopped half way from the mark he called it 0.5 second, instead 
of two-fifths or three-fifths. From the well known principle of stop 
watches, this seemed to me a rather surprising way of reading it.
