Relation of Weight to Height during Adolescence

MY friend, Mr. D. Caradog Jones, who during his stay in Manchester was my collaborator in the anthropometric work which has been carried on at the Manchester Grammar School for so many years, has directed my attention to his contribution to NATURE of April 10, and has asked me to make some further comments. I gladly do so, partly as an acknowledgment of the help which he so unstintingly gave me and partly because I am also indebted to Prof. Dreyer for the interest he showed in 1921 in the work at the Grammar School, and the help I have gained from his numerous attempts to connect body measurements with accepted standards of body metabolism.
