ADVERTISEMENT TO THE READER.

THE greater part of the substance of the following Essays has already been published in the form of Oral Discourses, addressed to widely different audiences, duṛing the past three years.

Upon the subject of the second Essay, I delivered six Lectures to the Working Men in 1860, and two, to the members of the Philosophical Institution of Edinburgh in 1862. The readiness with which my audience followed my arguments, on these occasions, encourages me to hope that I have not committed the error, into which working men of science so readily fall, of obscuring my meaning by unnecessary technicalities: while, the length of the period during which the subject, under its various aspects, has been present to my mind, may suffice to satisfy the. Reader that, my conclusions, be they right or be they wrong, have not been formed hastily or enunciated crudely.
