My aim has been not only to describe and illustrate in a familiar manner the principal laws and phenomena of light, but to point out the origin, and show the application, of the theoretic conceptions which underlie and unite the whole, and without which no real interpretation is possible.\u003cbr\u003eThe Lectures, as stated on the title-page, were delivered in the United States in 1872-3. I still retain a vivid and grateful remembrance of the cordiality with which they were received.\u003cbr\u003eMy scope and object are briefly indicated in the 'Summary and Conclusion,' which, as recommended in a former edition, might be, not unfitly, read as an introduction to the volume.\u003cbr\u003eJ.T.\u003cbr\u003eALP LUSGEN: October 1885.","brand":"Unforgotten Classics","offers":[{"title":"Default Title","offer_id":47147777065200,"sku":"2940014935135","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014935135_p0.jpg?v=1763617730","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014935135","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
