A stiff letter galls one like a stiff shirt collar -- whilst a sheet garnished here and there with a careless blot -- and here and there a dash -- but in the main full of excellent matter, is like a clever fellow in a dirty shirt whom we value for the good humour he brings with him and not for the garb he wears.
