This, however, is no great disadvantage, since we can always calculate the proportional quantities in any number of parts we may choose. The former method may sometimes be adopted, the weighing being performed in a dish which may serve also for the evaporation, thus doing away with the necessity of removing the fluid from one vessel to another. The weight of solid animal matters should be taken in an accurately balanced watch-glass, placed upon a curl of paper, which prevents its slipping from the operator; an inconvenience occasionally very distressing during manipulation, but which may be easily obviated by this simple expedient. Before quitting this subject, I must urge upon the reader the propriety of noting with the greatest care the result of every weighing performed during an analysis. I shall now proceed to describe the contri- vances adopted for procuring that degree of heat which may be requisite for the purposes we have in view, and shall notice some chemical implements eminently useful in the prosecution of animal ana- lysis. Water-hath. — This may be divided into two kinds, viz. the fresh and salt water-bath. The former is formed by floating a dish in water, which is kept at a boiling temperature by means of a lamp
