It is the admitted maxim, that if smoking is accompanied by spitting, injury results to the smoker; and the reason assigned is, that the salival fluid, which should assist digestion, is in this manner dissipated, and taken from its office. But may not the habitual application of the narcotic influence to the nervous system have its evils also? May it not weaken or deaden the nervous and muscular action which is needful to digestion? And may not even the excessive quantity of the matter of heat, thus artificially conveyed into the body, tend to a desiccation of the system, as injurious under general circumstances, as it may be beneficial under particular ones? Smoking invites thirst; and there is little risk in advancing, that whatever superinduces an unnatural indulgence in the use of liquids is itself, and without farther question, injurious, even if the liquids resorted to are of the most innocent description; but, in point of fact, the cigar-smoker will usually appease his thirst by means of liquors in themselves his enemies! It is said, however, that the use of cigars is beneficial when we find ourselves in marshy situations, with a high temperature, and generally, whenever the atmosphere inclines to the introduction of putridity and fever into the system. We believe this; and perhaps a useful theory of the alternate benefit and mischief of cigar-smoking may be offered upon the basis of that proposition. When and wherever the body requires to be _dried_, cigar-smoking may be salutary; and when and wherever that _drying_, or desiccation, is injurious, then and there cigar-smoking may be to be shunned. We know that, while surrounded by an atmosphere overcharged, or even only saturated with moisture, moist bodies remain moist, or do not part with that excess of moisture from which a drier atmosphere would relieve them; and that living bodies, so circumstanced, are threatened with typhus and typhoid fever. It is highly probable, therefore, that narcotics, in such cases, may allay a morbid irritability of the nerves, or effect a salutary diminution of healthful sensibility; under such circumstances, the desiccating and sedative effects of tobacco-smoking may prove beneficial; while, in all ordinary states of the system and of the atmosphere, the same desiccative and sedative influences may produce immediate evil consequences, more or less readily perceptible, and undermine, however gradually, the strength of the constitution.--_United Service Journal._ * * * * * THE NEW COINAGE. Why does not some man of public research enlighten the public on the proceedings at the Mint? The whole system is as little comprehensible by the uninitiated as the philosopher's stone. The cost of the Mint is prodigious--the machinery is all that machinery can be; yet we have one of the ugliest coinages of any nation of Europe. A new issue of coin is about to be commenced.
