TABLE I 



Uca pugnax (401 Specimens) Growth-ratio of Large Chela {y) 



and Rest of Body (x) 



(a) First phase: to total weight (x + y) = i-i g. y = 0-0073 * 162 ( m g-)' 



Algebraic sum of deviations 4- 2-9 

 Mean deviation 4-0-19 



— 16-9 



- i-i3 



In Huxley, 1927A (p. 152), this was stated as 1-33 owing to an error.
