Excerpt from Elements of Chemistry, Theoretical and Practical, Vol. 1 The principal changes in this Edition consist in theadoption of the new system of Atomic Weights, with the method of notation dependent upon it; and the introduction of the Centigrade values for degrees of temperature, in addition to those on Fahrenheit's Scale, as well as of the Metrical Equivalents to the English weights and measures, employed in the description of processes and apparatus. The use of barred letters to denote the symbols applied to the new atomic weights has been discontinued, as it is no longer necessary, inasmuch as the new values alone are employed in the present Edition. There may be considerable difference of opinion as to the expediency of endeavouring to introduce the metrical system of weights and measures into the transactions of commerce, and the concerns of daily life. But there is a general and increasing desire amongst men of science to secure the adoption of some uniform system in the scientific writings of men of all countries. It would not be difficult to show that the metrical system has its defects. But it is founded upon principles that are simple, intelligible, and consecutive, and it is capable of convenient application.
