Chemistry I deem to be the foundation of all other science, and in a manner pf speaking to comprise all other branches of science. As matter and motion comprise everything we can behold or conceive, and as Chemistry is an investigation of the properties of matter, with the causes and effects of its various combinations, it is evidently the most important part of science, or rather, the first and last part of it. The cultivation of the earth--the cookery of our food--its quantity and quality, and every thing connected with feeding the body--the preservation of our health, and the very preparation of our clothing, may be said to be comprised in the terms chemical analysis and composition. There is no one part of the Arts and Sciences, but to which Chemistry has relation, and even the most important relation. In all manufactures, whether wood or metal--clay or stone--wax or glass--paper or cloth, or what not, the knowledge of Chemistry is essential. It is to the science of Chemistry that we owe all our artificial productions, it is to the science of Chemistry that we owe all our knowledge and comprehension of natural productions, and their adaption to our several uses. It is therefore of the first consequence that we should commence our studies in this all important science, even in our infancy. As the Science of Chemistry embraces so extensive a variety of objects, it is not without a class simple enough for the comprehension of children. The burning of a candle is a chemical experiment for the production of light--the burning of the fuel which keeps up our fires, is but a chemical experiment for the production of heat; to which a thousand might be added equally simple, a definition of which could not fail to be of the greatest importance in the education of children. And why might not even the first lessons of children be comprised of these and similar simple chemical experiments, which beyond every other subject must instruct and amuse, attract the child's particular attention, and expand its mind by filling it with correct ideas?
