" The path of discovery is often a very tortuous one, and when a discovery can 

 only be made by a series of observations, the fact that these observations are made 

 singly, and only form a series when collected together, is often a real diliiculty in 

 the path of the philosophic student. Some try, indeed, to generalize from every 

 individual fact, but surely they impede then* own progress thereby, and nothing 

 can be more distressing than to see great powers misapplied, in the vain attempt 

 construct theories, for which the facts are not accumulated." — Stainton.
