    PREFACE. The following Tables and Diagrams have for their object to illustrate that part of Chemistry which relates to the com- binations of simple substances, and the various changes to which those combinations are liable. This is the most im- portant department of the science. It has, by the discovery and extension of the atomic doctrine, attained to a high degree of precision, and seems destined to raise Chemistry, ere long, to the rank of an exact science. Considering the importance of this subject, it has appeared to me, that the illustration of it, by means of diagrams and tabular views of a comprehensive kind, has not been carried to that extent which it might be with advantage. In the follow- ing pages I have endeavoured to supply this deficiency, part- ly by tables presenting the atomic constitution of compound substances, and partly by diagrams, which exhibit the reac- tion between the elements of those substances, leading to the formation of new products. I have placed the diagrams first, as I wish to direct atten- tion to them chiefly; and it is easy to refer to the subsequent tables, for the composition of any substance concerned in the reactions which they represent. The form of diagram, of which I make use, is one contrived some years ago by Dr D. Boswell Reid, and which seems to be admirably adapted for presenting, in a clear and precise manner, the nature and re- sults of such reaction. Some of these diagrams have been already published : others I have used in the illustration of my Lectures ; but the greater number have not appeared before in
