The emotions that attend the birthday celebrations of an individual are often a mixture of joy and sadness, of laughter and of tears. In warm and imaginative youth there is no sadness and there are no tears, because that cognizance of the common end which is woven into the very warp and woof of existence is then buried deep in our subconscious natures, or if it impresses itself at all, is too volatile and fleeting to be remembered. But as the years fall away and there is one less spring to flower and green, the serious man "tangled for the present in some parcels of fibrin, albumin, and phosphates" looks forward and backward and takes in both this world and the next. In the case of institutions, however, the sadness and the tears do not obtain--for a century of anniversaries may merely mean dignified maturity, as in the case of Bloomingdale, with no hint of the senility and decay that must come to the individual who has lived so long. This institution was founded one hundred years ago to-day; the parent, the New York Hospital, has a longer history. Bloomingdale, as a separate and independent concern, had its birthday a century ago. It is curious to let the mind travel back, and consider what was happening about that time. Just two years before the news had flashed on the philosophical and scientific world that Oersted, a Danish philosopher, had caused a deflection of the magnetic needle by the passage near it of an electric current. The relation between the two forces was then and there confirmed by separate observations all over the civilized world. This discovery probably created more interest at that time than Professor Einstein's recent announcement which, if accepted, may be so disturbing to the principia of Newton and to our ideas of time and space. There can be no doubt that the practical significance of Oersted's experiment was much more widely appreciated than the theory of Einstein, for an understanding of the latter is confined, we are told, to not many more men than was necessary to save Sodom and Gomorrah. Its immense practical significance, however, could have been foreseen by no man, no matter with what vision endowed. Just two years prior to the founding of this institution the first steamboat had crossed the Atlantic and in the same year that great conqueror, who had so disturbed the peace of the world which was even then as now slowly recovering from the ravages of war, breathed his last in Saint Helena, yielding to death as utterly as the poorest hind.
