Various, Chambers's Journal of Popular Literature…
“ There is no royal road to the art which places length of days within the right hand of a nation, any more than there exists an easy pathway to full and perfect knowledge in any other branch of inquiry. It is the duty of each individual, as a matter of self-interest, if on no higher grounds, to conserve health; and the knowledge which places within the grasp of each man and woman the power of avoiding disease and prolonging life, is one after all which must in time repay a thousandfold the labour expended in its study. ”
