Alison observes that an autumn sunset, with its crimson clouds, glimmering trunks of trees, and wavering tints upon the grass, seems scarcely capable of embellishment. But if in this calm and beautiful glow the chime of a distant bell steal over the fields, the bosom heaves with the sensation that Dante so tenderly describes.

The history of men of science has one peculiar advantage, as it shows the importance of little things in producing great results.
