PREFACE Vll 



lations throughout the book, and in the construction of 

 the tables. 



To my colleague, Dr. G. Druce Lander, thanks are 

 due for some of the analyses of foods, and for valuable 

 suggestions in connection with those chapters dealing 

 more particularly with chemistry. 



Whilst the calculations and tables have been repeatedly 



checked, it is possible that some numerical mistakes still 



remain. If the kindly reader will point out any he may 



discover, I shall be obliged, and it will make for accuracy 



in any future edition.
