This is the way in which the advocates of total abstinence like to begin. A good round assertion about "poison" is calculated to demoralize the inexperienced reader, and to scare him into half giving up the case at once. But it is not all barking dogs that bite. Morphia is a deadly poison; but opium, which contains it, is not "the mortal foe of life in all its forms,"--it is sometimes the only thing which will keep soul and body together.[1] Theine is no doubt a deadly poison, but we manage to drink it with tolerable safety in our tea and coffee. Lactucin is probably a poison, yet people may eat a lettuce-salad and live. Chlorine is eminently a poison, yet we are all the time taking it into our systems, combined with sodium, in the shape of table-salt. Therefore over the verbal question whether a teaspoonful of pure alcohol is a poison, we do not care to wrangle. People do not drink pure alcohol, as a general thing. And as for the beverages into the composition of which alcohol enters, the reader will have no difficulty in understanding that they are poisons in just the same sense in which common salt and oxygen are poisons; _i.e._, if you take enough of them, they will kill you. This point was sufficiently cleared up in our first chapter. [1] Opium, as used in moderation by Orientals, has not been proved to exercise any deleterious effects. Very likely it is a healthful stimulant; but it does not appear to agree with the constitutions of the Western races. See Pharmaceutical Journal, vol. xi. p. 364. Probably tea, tobacco and alcohol are the only stimulants adapted alike to all races, and to nearly all kinds of people. Mr. Parton's hostility to this "mortal foe of life in all its forms" has taken shape in six definite propositions. Concerning alcoholic liquor of any kind and in any quantity, he asserts, and attempts to prove, that it does not nourish, that it does not aid digestion, that it does not warm, that it does not strengthen, that it undergoes no chemical change in the system, and that it always injuriously affects the brain. Beginning with the last of these propositions, let us first see what Mr. Parton has to say for it.
