interested myself in a point of view derived, in its essence, from 

 my predecessor as Professor of Physiology here, Professor 

 Sherrington. Of the prestige obtainable by utilising his name 

 in this place specially, but as a matter of fact similarly in any 

 place where Biologists are met together, I am fully aware, and 



1 do not intend to press it unduly in relation to a statement 

 which stands on its own foundation. According to my examina- 

 tion of these accounts, there is no " rest " in movement, and 

 no allowance is made for it. According to Sherrington, "rest " 

 is, in a sense, a movement, which is replaceable therefore 

 completely by other, different, movements. I need not then 

 allude again to the fact that no subtraction is made in any of 

 my accounts for phenomena of any kind, such as is usually 

 done in writing off the debit due to rest, and that it is really 

 the case that movement and work are balanced against total 

 temporary expense. 



I am afraid that there are other points in which I can make 

 no claim for orthodoxy. They are not of the same essential 

 importance since not affecting the mode of stating the accounts, 

 but are perhaps worth some brief allusion. You will not find, 

 for example, any attention paid to characteristics of the sub- 

 jects of my experiments other than their body- weight. It is 

 true that I would like to pay attention to the lengths of their 

 limbs, but have failed to do so adequately, that is to s&y, to 

 such a degree as to place direct measurements of length in 

 certain positions now occupied by statements of body- weight, 

 with which after all these lengths, in the average, vary. Nothing 

 is said as to age, diet, habit and other matters to which promin- 

 ence is usually given — and that not without thought, but 

 because the supposed necessity for dealing with these points 

 has never arisen. In my earlier experiments subjects were 

 chosen who differed from one another in certain directions 

 very remarkably. Comparing in them the results, on the one 

 hand of habits which made for social eminence, and on the 

 other for complete failure, I found no distinctions with regard
