ADDRESS. 



To the Scientific World generally, I beg leave to observe, in 

 defence of the STARTLING ASSERTIONS I am (with such 

 apparent presumption) about to present for their most rigid in- 

 vestigation, that I have been solely influenced by the unconquer- 

 able love of TRUTH with which I am impressed, and by which 

 I am urged again to proclaim opinions I have entertained, with 

 but little modification, for a period of NINETEEN YEARS ; during 

 which, every one, without exception, of the important discoveries 

 that have been made, that bear upon the subject of Light, 

 Heat, Electricity, the Voltaic influences, and Magnetic forces, 

 (and more particularly the IDENTITY of the three latter,) have 

 all conspired to substantiate my hypothetical views, and to 

 support and confirm the opinions I entertain of their rectitude. 

 I feel it my duty thus to submit the following " Theory of 

 Light" to the proper ordeal ; and, in addition to the testimonies, 

 analagous, collateral, and direct, which are at present adduced, 

 there is one unerring, and above all Evidence of Human 

 Philosophy, on which I confidently rely 



" And God said, Let there be LIGHT: and there was LIGHT." 



Genesis, chap, i. v. 3.
