We observe that the English in India suffer greatly from liver disease; whilst, on the other hand, negroes and natives frequently die of phthisis (consumption) in England. Monkeys die of consumption, so do lions and tigers. This is a very important fact in the pathology of phthisis, as tending to prove that although phthisis is in many instances distinctly hereditary, nevertheless it may be, and is, frequently acquired. Nothing can furnish a stronger proof that phthisis may be acquired than the instances I have adduced, for I need not tell you that no lion or tiger is ever born in warm climates of a consumptive sire, or ever dies there of tubercular disease. An additional illustration of the influence heat exercises on the size of the liver is afforded by the celebrated Strasburg geese. By feeding these birds in a particular way, and keeping them in artificial heat, the liver becomes diseased, grows to an enormous size, and in this state furnishes the materials of the famous pâté. How many instances occur where our citizens, exposing themselves to the long continued operation of the very same causes, confinement, overfeeding, heat, and want of exercise, are affected by them in exactly the same way! How slight the difference between the morbid phenomena displayed in the post-mortem of a city feaster and the autopsy of an over-fed goose.

Perfumes.

A knowledge of the nature and operations of Perfumes is a very proper thing to propagate. Ignorance respecting them often leads to mischief. Dr. Capellini relates the story of a lady who fancied that she could not bear the smell of a rose, and who accordingly fainted at the sight of one, which turned out to be artificial! This is rather an extreme case; but minor mistakes, adverse to the use of perfumes, are very common. Many persons suppose that they are injurious, because flowers left in a bedroom by night, will sometimes cause headache and sickness. But this is attributable, not to the escaping aroma, but to the carbonic acid which the air imbibes from the flowers. On the other hand Mr. Rimmel contends that perfumes are beneficial and prophylactic in the highest degree. He reminds us that after the Dutch had destroyed, by speculation, the clove-trees in the Island of Ternate, that colony was visited by a series of epidemics, which had been kept off until then by the fragrant smell of the cloves; and in more modern times, when London and Paris were ravaged by cholera, there was not a single victim among the numerous persons employed in the perfumery factories of either city.

Cure for Yellow Fever.

A private letter from Her Majesty’s Vice-consul at Cape Bolivar to Her Majesty’s Acting Consul-General at Caracas states:—“An old woman, named Mariquita Orfila, has discovered a perfect remedy for the black vomit and yellow fever, by means of which several persons have been completely cured after a consultation of doctors had declared that the cases were quite hopeless, and that the patients must die in a few hours. The remedy is the juice of the pounded leaves of the verbena, given in small doses three times a day, and injections of the same every two hours, until the bowels are emptied. The verbena is a wild shrub, to be found growing almost everywhere, and particularly in low, moist ground. All our doctors have adopted its use, and now few or none die of those late fearful diseases. There are two kinds of it, male and female; the latter is most used.”

Nature’s Ventilation.

Upon the proper adjustments of the dynamical forces which keep up the ceaseless movements of the atmosphere, the life of organic nature depends. If the air that is breathed were not taken away and renewed, warm-blooded life would cease: if carbon, and oxygen, and hydrogen, and water were not in due quantities dispensed by the restless air to the flora of the earth, all vegetation would perish for lack of food. That our planet may be liable to no such calamity, power has been given to the wayward wind, as it “bloweth where it listeth,” to bring down from the pure blue sky fresh supplies of life-giving air wherever it is wanted; and to catch up from the earth, wherever it may be found, that which has become stale; to force it up, there to be deflagrated among the clouds, purified and renovated by processes known only to Him whose ministers they are. The slightest change in the purity of the atmosphere, though it may be too slight for recognition by chemical analysis in the laboratory, is sure to be detected by its effects upon the nicer chemistry of the human system; for it is known to be productive of disease and death. No chemical tests are sensitive enough to tell us what those changes are; but experience has taught us the necessity of ventilation in our buildings, of circulation through our groves. The cry, in cities, for fresh air from the mountains or the sea, reminds us continually of the life-giving virtues of circulation. Experience teaches that all air, when pent up and deprived of circulation, becomes impure and poisonous. In referring to ventilation, we are never to forget that, in order to secure Nature’s pure air, it is essential to guard against the many sources of its pollution. The air which descends to us is pure; but it is left to man to maintain it so; hence we have to drain our marshes, empty foul ditches, remove cesspools, and see that our streets are sewered and paved. The Deity has given laws for the moral government of society; but He leaves to man, on whom He has bestowed intelligence, the discovery and the application of those scientific means which are necessary to health and physical happiness.—Captain Maury.

Artificial Ventilation.

In Wyman’s Practical Treatise on Ventilation we find these curious results. In a weaving-mill near Manchester, where the ventilation was bad, the proprietor caused a fan to be mounted. The consequences soon became apparent in a curious manner. The operatives, little remarkable for olfactory refinement, instead of thanking their employer for his attention to their comfort and health, made a formal complaint to him that the ventilator had increased their appetites, and therefore entitled them to a corresponding increase of wages! By stopping the fan a part of the day, the ventilation and voracity of the establishment were brought to a medium standard, and complaints ceased. The operatives’ wages would but just support them; any additional demands by their stomachs could only be answered by draughts upon their backs, which were by no means in a condition to answer them. In Edinburgh a club was provided with a dinner in a well ventilated apartment, the air being perfumed as it entered, imitating in succession the fragrance of lavender and the orange-flower. During dinner the members enjoyed themselves as usual, but were not a little surprised at the announcement of the provider, that they had drunk three times as much wine as he had usually provided. Gentlemen of sober, quiet habits, who usually confined themselves to a couple of glasses, were not satisfied with less than half a bottle; others, who took half a bottle, now extended their potations to a bottle and a half. In fact, the hotel-keeper was drunk dry. That gentlemen who had indulged so freely were not aware of it at the time is not wonderful; but that they felt no unpleasant sensations the following morning, which they did not, is certainly quite so.
