Excerpt from A Practical Treatise on Warming Buildings by Hot Water, and an Inquiry Into the Laws of Radiant and Conducted Heat: To Which Are Added, Remarks on Ventilation, and on the Various Methods of Distributing Artificial Heat, and Their Effects on Animal and Vegetable Physiology There is scarcely any branch of science or of art, in which an acquaintance with the laws of Nature does not enable us to derive greater advantages in its application, than we could otherwise possess. Although it is true that we are still ignorant of the more subtile agents which exist in the vast chain of causation, the laws which regulate the various phenomena of nature, are sufficiently known to afford the most beneficial assistance to every branch of the arts and sciences: and the most recon dite of scientific discoveries, as well as the most valuable inventions and improvements in the arts, are not more demonstrative of the truth of this assertion, than are those of the most simple characters.
