Excerpt from A Manual of Photography: Founded on Hardwich's Photographic Chemistry
Ir will be necessary to make a few remarks by way of Preface to this edition of Mr. Hardwich's treatise on Photography. The short compendium of general Chemistry has been omitted, because this Science can be better studied from the more comprehensive works on that subject which now abound. Indeed, a know ledge of Chemistry is not essential to the practical Photographer, for it is only on very exceptional occasions that he will be called on to prepare any of his own Chemicals. At the same time it is deemed desirable to give a Vocabulary, mentioning the nature and properties of the various substances used in Photo graphy, except when these are described in the body of the work.

Excerpt from A Manual of Photography: Founded on Hardwich's Photographic Chemistry
The Art of Photography, which has now attained such perfection, and has become so popular amongst all classes, is one of comparatively recent introduction.
The word Photography means literally "writing by means of Light;" and it includes all processes by which any kind of picture can be obtained by the chemical agency of Light, without reference to the nature of the sensitive surface upon which it acts.
The philosophers of antiquity, although chemical changes due to the influence of Light were continually passing before their eyes, do not appear to have directed their attention to them. Some of the Alchemists indeed noticed the fact that a substance termed by them "Horn Silver," which was Chloride of Silver which had undergone fusion became blackened by exposure to Light; but their ideas on such substance termed by them "Horn Silver," which was Chloride of Silver which had undergone fusion, became blackened by exposure to Light; but their ideas on such subjects beings of the most erroneous nature, nothing resulted from the discovery.
The first philosophical examination of the decomposing action of Light upon compounds containing Silver was made by the illustrious Swedish chemist, Scheele, in the year 1777. It was remarked by him that the maximum chemical or decomposing effect of the spectrum lay near the violet part and gradually diminished towards the red. He also attributed the blackening of Chloride of Silver by light to the liberation of Chlorine and the formation of Hydrochloric acid. Both of these statements have been proved to be true.
