Chemistry : general, medical, and pharmaceutical including the chemistry of the ; a manual on the general principles of the science, and their applications in medicine and pharmacy . other compound is produced and its formula. The context ofhis Manual will generally afford this information, or, after a littleexperience is acquired, analogies or his own knowledge will suggestcorrect formulae. In this case carbonate of calcium is (This product is, in fact, precipitated chalk, together withany excess of slaked lime and any natural impurities in the slakedlime. Pure precipitated chalk is made by an analogous reactiondescribed subsequently.) The source of the elements of the carbonate of calcium and. finally,their union, must be indicated just as the source and mode of forma-tion of the potash were indicated. That is to say, after the formulaof this second substance produced (CaC03) is written on the right of the diagram, thus :• K2C03 { 2KHO Ca2HO 2HO CaCO, the source of its elements is shown by writing the symbols for thoseelements on the right of the bracket attached to the formula con-taining the symbols of the elements, thus :— 2KHOK,COa CV2HO. CaCO, Lines converging from the symbols of the elements and uniting atthe formula of the substance are then drawn, to suggest approach of HYDRATE OF POTASSIUM. 65 the atoms of the elements and their union to form a molecule of thecompound. The diagram will now be complete, thus :— K2C03 {& - Ca2HO
