Here therefore, as in all other branches of natural science, 

 much has been added to our knowledge; while yet there 

 remain many facts to be discovered and questions to be 

 solved. In this the strength of science is shown, and not its 

 weakness. It has' futurity to work in, zeal for the work, and 

 methods of research ever becoming more ample and more 

 exact. Whether on land or sea, whether among the higher 

 forms of life or the lowest, it is ever pursuing its straight 

 and assured path towards a more perfect knowledge of the 

 natural world.
