CONCLUSION.
There is no branch of science that holds such an intimate relation to the progress and welfare of man as chemistry. First of all, it is chiefly instrumental in providing him with food and clothing, as has been shown in the paragraph on agricultural chemistry. In the second place it has extended his domain over matter and, in connection with physics, has established the identity of the composition of the universe with that of the earth. The universe has thus been shown to be of a single origin and of uniform properties. By understanding the constitution of matter, with which he is surrounded, man is able to utilize to the best advantage the material at his disposal. Thus invention is promoted and the application of chemical knowledge in the arts extended.
