(In- stead of placing the evaporating basin in hot sand, it can be heated by the steam rising from boiling water, as in Fig. 80.) Allow the water to slowly boil away. When all the water has been changed into steam, the salt will be found left behind in the bdsin. Repeat the experiment in the following manner. Weigh.
