'Be careful not to keep your eyes glued to detail,' says History Professor. 'Stand far enough away to get perspective of the whole.'
You can see with what nicety we have to trim our sails between chemistry and history. I like historical method best. If I say that William the Conqueror came over in 1942, and Columbus discovered America in 1100 or 1066 or whenever it was, that's a mere detail that Professor overlooks. It gives a feeling of security and restfulness to the history recitation, that is entirely lacking in chemistry.
Sixth-hour bell--I must go to the laboratory and look into a little matter of acids and salts and alkalies. I've burned a hole as big as a plate in the front of my chemistry apron, with hydrochloric acid. If the theory worked, I ought to be able to neutralize that hole with good strong ammonia, oughtn't I?
