of natural knowledge be gained. By nothing but 

 patient toil and the quiet thought which it brings can 

 a scientific habit of mind be acquired. No amount of

 investigation. New treasures can never be secured 

 from Nature without effort ; " tribulation, not undis- 

 turbed progress, gives life and soul, and leads to success, 

 when success can be reached, in the struggle for natural 

 knowledge." 



Success in science means the birth of new knowledge. 

 Patient observation and productive thinking are what

 study demands. There are now so many opportunities 

 of obtaining ready-made opinions that the habits of 

 independent thought, caution in accepting assertions, 

 and critical inquiry into evidence, are becoming atrophied 

 by disuse. Vox populi, vox Dei may be a sound demo- 

 cratic principle for political platforms, but it stands for 

 nothing in science. The men who have advanced the 

 human race throughout the ages are those who have 

 stood for individuality as against the conclusions of the 

 crowd. Cultivate appreciation for beauty, the instinct 

 for truth and the creative power, and all the rest shall 

 be given unto you. In Nature 



Beauty is truth, truth beauty ; that is all

Truth, Beauty, Learning, Observation, Reason, 

 Expression, Production, are powers which all of us 

 possess in varying degrees ; and the greatest of the seven 

 is Production, whether it be applied to literature, art, 

 or science. 



The all-round liberally-educated man, from Palaeolithic times 

 to the time when the earth shall become a cold cinder, will always
