Reasons for merely, at present, naming, without examining, the particular effects of light rendered by Turner

Hopes of the author for assistance in the future investigation of them.

I have before given my reasons (Sect. II. Chap. III.) for not wishing at present to enter upon the discussion of particular effects of light. Not only are we incapable of rightly viewing them, or reasoning upon the them, until we are acquainted with the principles of the beautiful: but, as I distinctly limited myself, in the present portion of the work, to the examination of general truths, it would be out of place to take cognizance of the particular phases of light, even if it were possible to do so, before we have some more definite knowledge of the material objects which they illustrate. I shall therefore, at present, merely set down a rough catalogue of the effects of light at different hours of the day, which Turner has represented; naming a picture or two, as an example of each, which we will hereafter take up one by one, and consider the physical science and the feeling together.
