the cube of the length. ^ Meek ('05), continuing his work, showed 

 that the weight-length relation which he had established for 

 the plaice was also true for the sole, the dab, the flounder, and 

 the turbot. At the suggestion of D'Arcy Thompson, Heincke 

 and his co-workers adopted this cube relationship and used it

1 I, too, have found this to be the case with one or two species. The increase, 

 although very regular, is, however, well within the limits of variation, and if 

 an average be taken of the values of the coefficient at different parts of the curve, 

 the variation produces no larger error than that found in the species which con- 

 form to the simpler cube relationship.
