We must not forget the various medical libraries which preceded this: that of an earlier period, when Boston contained about seventy regular practitioners, the collection afterwards transferred to the Boston Athenaeum; the two collections belonging to the University; the Treadwell Library at the Massachusetts General Hospital; the collections of the two societies, that for Medical Improvement and that for Medical Observation; and more especially the ten thousand volumes relating to medicine belonging to our noble public city library,--too many blossoms on the tree of knowledge, perhaps, for the best fruit to ripen. But the Massachusetts Medical Society now numbers nearly four hundred members in the city of Boston. The time had arrived for a new and larger movement. There was needed a place to which every respectable member of the medical profession could obtain easy access; where, under one roof, all might find the special information they were seeking; where the latest medical intelligence should be spread out daily as the shipping news is posted on the bulletins of the exchange; where men engaged in a common pursuit could meet, surrounded by the mute oracles of science and art; where the whole atmosphere should be as full of professional knowledge as the apothecary's shop is of the odor of his medicaments. This was what the old men longed for,--the prophets and kings of the profession, who “Desired it long, But died without the sight.” This is what the young men and those who worked under their guidance undertook to give us. And now such a library, such a reading-room, such an exchange, such an intellectual and social meeting place, we behold a fact, plain before us. The medical profession of our city, and, let us add, of all those neighboring places which it can reach with its iron arms, is united as never before by the commune vinculum, the common bond of a large, enduring, ennobling, unselfish interest. It breathes a new air of awakened intelligence. It marches abreast of the other learned professions, which have long had their extensive and valuable centralized libraries; abreast of them, but not promising to be content with that position. What glorifies a town like a cathedral? What dignifies a province like a university? What illuminates a country like its scholarship, and what is the nest that hatches scholars but a library?
