APPENDIX V. 



SIR DAVID BREWSTER ON INDUCTION. 



"In a letter from Tycho Brahe to Kepler, the great observer 

 urges his pupil ' to lay a solid foundation for his views by actual obser- 

 vations, and then by ascending from these to strive to reach the cause 

 of things: " 



" The reasonings of Copernicus, who preceded Bacon by more 

 than a century, were all founded upon the most legitimate induction." 



" Leonardo da Vinci had described in the clearest manner the 

 proper method of philosophical investigations." 



"The whole scientific career of Galileo was one continued 

 example of the most sagacious application of observation and ex- 

 periment to the discovery of general laws." 



"Dr. Gilbert had exhibited in his treatise on the Magnet the 

 most perfect specimen of physical research." (Newton, p. 331.)
