Odd as it may seem, the condition of the atmosphere has a powerful influence on the animal spirits. It is the mercury in the thermometer of mind, indicating its buoyancy or depression. Who that is an observer of human nature under its various peculiarities, has not been forcibly struck with the vast difference in any one intimate friend, both as to mental activity and sprightliness, on a beautiful, bright, balmy May morning, and on a cold, cheerless, comfortless, cloudy, rainy day in the same “moon”? The whole man is changed—disposition, manner, mind and temperament have undergone some radical metamorphosis. The very mode of thought, the sentiments, the opinions even, are inverted. He who was amiable, instructive, communicative, and lively, is suddenly, by the veering of the wind, changed into a sullen, sombre, morose cynic, restless, moody and taciturn. Conversation is abandoned for long sighs, deep respiration, involuntary growls and lugubrious interjections. The agreeable companion of a clear atmosphere is the thus altered being on _a Rainy Day_, and the influence that has wrought a change so inimical to individual and domestic economy, is that of the atmosphere. To account for the cause is more the province of a scientific pen. Whether electricity be most positive or negative in certain conditions of the barometer, is a subject for professors of the various “’isms” and “’icities” of the day. The effect is too apparent to doubt the existence of a cause, and the cause too involved in mystery, to invite discovery by one unlearned in the theories of Royal “Societies” or Republican “Schools.” “The Atmosphere: _Its Ingredients and Influences_,” by John Smith, Fellow of the Royal Society: London 8vo. “Electricity: _Its Cause, Combinations and Effects_,” by Charles Jones, M.

These, and the like publications, issuing almost daily, lasting monuments of the power of the steam-press, are far too repulsive food for the uninitiated in the art of philosophical digestion. We leave them to the student, who, with fortitude sufficient for the effort, will undertake the study of them on _a Rainy Day_.
