A variable climate

1418. A variable climate, such as ours, admits of being studied, both generally and locally; but it is a study which requires habits of observation and reflection, like all other studies; and, to be brought to any useful degree of perfection, it must be attended to not as it commonly is, as a thing by chance, and which every body knows, or is fit for, but as a serious undertaking. The weather may be foretold from natural data, artificial data, and from precedent.
