occur under the twentieth year. Let those who have these things in
charge answer to their own consciences how they discharge their duty in

requisite for _healthy bodies_ and _sound minds_."

On the subject of infant mortality the experience of savages should

seen a sick boy among the Indians." Catlin, the painter, who resided
and traveled so much among these people, states that infant mortality

and pure air.

Dr. Dio Lewis, whose labors in the cause of health are well known, in
his very useful work, _Weak Lungs and How to Make them Strong_, says:

"As a medical man I have visited thousands of sickrooms, and have not
