worn maxim, and one that, although quoted o'er and o'er, is always welcome to the ear. When man can properly appreciate the value of this study his progress will be far more rapid and beneficial. The more Physiology is understood the happier does man live. A great many valuable lessons can be learnt from it. He can learn how to save his fellow-creatures from agony, and often prevent a premature death; can discover the injurious effects of poisonous stimulants upon his constitution; can analyse every part of his body in order to have a better knowledge of its functions than he could by merely watching its effects; and, finally, can make laws—laws in accordance with nature's workings, which shall keep his health intact, and cause him to find that "life is real, life is earnest," and that it can only be properly enjoyed and appreciated by being assisted instead of being misunderstood. Medicine was tolerably well understood amongst the ancients, and they paid especial attention to the benefits to be derived from healthful exorcises. Later on, however, in the Middle Ages, people did not pay proper attention to their bodies; they were uncleanly and intemperate in their habits, and did not pay any attention to the ventilation of their houses, nor the sanitary conditions generally of the towns and villages in which they dwelt. And what was the result? They were visited on all sides by famine, disease, and fever; and in the fourteenth century were visited with the terrible Black Death, the horrors of which the pen of a Milton could not describe, nor the pencil of a Doré illustrate. But men are now living in an age of science and they have reason to be thankful for their good fortune. A man may now live in comparative happiness with very little chance of unknowingly infringing the laws of his nature; if he is sick, the means are in his reach to procure relief; if he suffers from fever, he knows that it is caused by bad drainage, or some other careless oversight—maybe insufficient ventilation and stifled atmosphere; if he be a drnnkard, the blame is upon himself, even thongh he be led into it by others, for he has perfect freedom of his will in such a case, and must be well aware from the experience gained by others,
