B. G. Jefferis and J. L. Nichols, Searchlights on Health — How to Have Beautiful Children (1919)
“ PARENTAL INFLUENCE.—The art of having handsome children has been a question that has interested the people of all ages and of all nationalities. There is no longer a question as to the influence that parents may and do exert upon their offspring, and it is shown in other parts of this book that beauty depends largely on the condition of health at the time of conception. It is therefore of no little moment that parents should guard carefully their own health as well as that of their children, that they may develop a vigorous constitution. There cannot be beauty without good health. ”
