ELEMENTS OF NATURAL PHILOSOPHY; 



BEING 



AN EXPERIMENTAL INTRODUCTION TO THE PHYSICAL SCIENCES. 

 Illustrated -witli over Tliree Hundred Wood-cuts. 



BY GOLDING BIRD, M.D., 



Assistant Physician to Guy's Hospital. 



From the Third London edition. In one neat volume, royal 12mo. 



We are astonished to find that there is room in so small a book for even the bare 

 recital of so many subjects. Where everything is treated succinctly, great judgment 

 and much time are needed in making a selection and winnow^ing the wheat from the 

 chaff Dr. Bird has no need to plead the peculiarity of his position as a shield against 

 criticism, so long as his book continues to be the best epitome in the English lan- 

 guage of this wide range of physical subjects.— iVoT-t/i American Review, April 1, 1851. 



From Prof. John Johnston, Wesleyan Univ., JSIiddletown, Ct. 

 For those desiring as extensive a work, I think it decidedly superior to anything of 

 the kind with which I am acquainted. 



From Frof. R. O. Currey, Fast Tennessee University . 



I am much gratified in perusing a work which so well, so fully, and so clearly sets 

 forth this branch of the Natural Sciences. For some time I have been desirous of ob- 

 taining a substitute for the one now used— one which should embrace the recent dis- 

 coveries in the sciences, and I can truly say that such a one is afforded in this work of 

 Dr. Bird's. 



From Frof. W. F. Hopkins, MasoJiic University, Tenn. 



It is just the sort of book I think needed in most colleges, being far above the rank of 

 a mere popular work, and yet not beyond the comprehension of all but the most accom- 

 plished mathematicians. 



ELEMENTARY CHEMISTRY; 



THEORETICAL AND PRACTICAL. 

 BY GEORGE FOAYNES, Ph.D., 



Chemical Lecturer in the Middlesex Hospital Medical School, &c. &c. 



WITH NUMEROUS ILLUSTRATIONS. 



Third American, from a late London edition. Edited, with Additions, 



BY ROBERT BRIDGES, M. D., 



Professor of General and Pharmaceutical Chemistry in the Philadelphia 



College of Pharmacy, &c. &c. 



In one large royal 12mo. volume, of over five hundred pages, with about 180 



wood-cuts, sheep or extra cloth. 



The work of Dr. Fownes has long been before the public, and its merits have been 

 fully appreciated as tlie best text-book on Chemistry now in existence. We do not, of 

 course, place it in a rank superior to the works of Brande, Graham, Turner, Gregory, 

 or Gmelin, but we say that, as a work for students, it is preferable to any of them. — Lon- 

 don Journal of Medicine. 



We know of no treatise so well calculated to aid the student in becoming familiar 

 with the numerous facts in the science on which it treats, or one better calculated as 

 a text-book for those attending Chemical Lectures. * * * * The best text-book on Che- 

 mistry that has issued from our press. — American Med. Journal. 



"We know of none within the same limits, which has higher claims to our confidence 

 as a college class-book, both for accuracy of detail and scientific arrangement.— .Au- 

 gusta Med. Journal.
