"The reasonings about the wonderful and intricate operations 

 of Nature are so full of uncertainty, that, as the Wise-man truly 

 observes, hardly do we guess aright at the things jhat are upon 

 earth, and with labour do we find the things that are before us.'' 

 Stephen Hales, Vegetable Staticks (1727), p. 318, 1738. 



"Ever since I have been enquiring into the works of Nature 

 I have always loved and admired the Simplicity of her Ways." 

 Dr George Martine (a pupil of Boorhaave's), in Medical Essays and 

 Observations, Edinburgh, 1747.
