fate to remain alive and yet lose the capacity of enjoyment or, what is even more important, the capacity of being enjoyed. If it be not an integral part of the personality of an old man or woman to present qualities of attractiveness to others, the fullness of life has not been attained. The factors which go to make up the quality of desirable and admirable old age are above all, first and foremost, self respect, an interest in the affairs of others, a dignity and kindliness, a patient and uncomplaining endurance and a capacity constantly exercised to be of use in the world. A woman, for instance, can if she give her undivided attention to it, grow old so charmingly that she may at great age attain more grace and fascination than she had in her youth or middle life. We all know instances of this truth though some are thus more blessed than others. A man again may become a greater power for good even when well past the age of so-called usefulness than at any previous time. Nor do these qualifications depend necessarily so much upon the original structure of mind or body as the maintenance of a faithful vigilance and conscious desire to be, and do, that which shall furnish forth these good attributes.

The principles of action upon which the effects of advancing years may be postponed are simple, clear and practicable. The difficulties are chiefly the indifference or indolence which age begets. Wherever a person has acquired an active desire to retain the freshness of youth and is moderately diligent in pursuing whatever means should be adopted, the results are successful often beyond expectation. The conditions of success are an original soundness of constitution and fairly healthy organs. It might be added reasonably comfortable circumstances, but I know several cases where the environment was far from satisfactory, and daily labor onerous, yet these people were not discouraged. One other condition might be mentioned as needed often, but not constantly, viz., the counsel of a wise physician. Medical advice ought to be more frankly and constantly sought for the lesser infirmities of age than during middle life for reasons obvious. As the internal resistances lessen small disorders more readily throw the actions of the organism out of balance, and fatal results follow seemingly small causes. Another prerequisite is consistency and persistence in the measures employed. The balance of power in the old is not easily retained, and regained with far greater difficulty. It is an axiom among horsemen that an old horse can be kept fit if used carefully and constantly, but once allowed to get into poor condition through disuse it can never be reinstated.

The potentiality of cellular cleanliness, and lymph activity, on the mechanism of life is paramount, and is not yet duly appreciated by men in or out of the profession of medicine.

Diet has been alluded to already and all that it is needful to say here is to repeat that temperance in food and drink is an essential
