Along the horizontal line the consecutive degrees of tempera- ture on the centigrade scale are marked and numbered. The volume which the quantity of water experimented with has at each degree of temperature is represented, on a convenient scale, by the height of the vertical lines erected over the points representing the degrees of temperature. When the tops of these verticals are joined in by a continuous line we have a.
