" The only possible check to the progress of Science is that the works on it are 

 becoming too voluminous; it is becoming scholastic: life will be too short to learn it, 

 and no time will be left for discoveries." GROVE. 



" The Truth must be told, whoever may be hurt by it. There is no doubt that some 

 writers endeavor to conceal in a fog of mere words the want of clear and well-defined 

 ideas, as well as of that critical knowledge which is indispensable in Natural History ; 

 and it is out of this that has arisen that legion of phantoms which so effectually 

 bewilder the inexperienced." Anon. Gardener's Chronicle, Dec., 1854.
