Abstract
IN reply to Dr. Bradford's letter1 I would say that the more comprehensive a theory is, the more general and apparently indefinite must be the terms in which it is expressed. If for my indefinite term ‘mobilisation’ is substituted the more definite term ‘adsorption’, my theory of periodic structures becomes almost identical with Dr. Bradford's. But I believe that adsorption is only one of the means by which the substance may migrate towards the structure already formed, and I prefer, therefore, to use the less definite term ‘mobilisation’ to include all these means.
