When giving lessons on Chapters IV and V, it is very desirable for a teacher to have at hand an articulated human skeleton. This may be purchased for about $40.00 from Henry Ward, Rochester, N. Y., and will last for an indefinite number of years. When the school funds do not permit the purchase of a skeleton, one can almost certainly be borrowed from some medical man or medical school for a few days. When there are several public schools in a city it would probably be possible to induce the school commissioners to purchase a skeleton to be used by the schools in turn.
