Roxey Ann Caplin, Health and beauty — Chapter V (1864)
“ We may therefore say that life is dependent upon voluntary as well as involuntary motion for its existence, and above all it may be affirmed, that a healthy and sound body is never seen, unless there has been proper daily exercise. For, as every function that we have named must be maintained in order that there may be a state of perfect health, so also the whole congeries of organs must be exercised together, in order that there may be nothing superfluous, and nothing wanting, in the entire fabric. ”
