Shaking the dust of the law office from his shoes, Oliver Wendell Holmes, abandoning literature for a time, plunged boldly into the study of a profession for which he had always evinced a strong predilection. The art and practice of medical science had ever a fascination for him, and he made rapid progress at the university. Once or twice he yielded to impulse, and wrote a few bright things, anonymously, for the _Harbinger_,--the paper which Epes Sargent and Park Benjamin published for the benefit of a charitable institution, and dedicated as a May gift to the ladies who had aided the New England Institution for the Education of the Blind. In 1833, Holmes sailed for Paris, where he studied medicine and surgery, and walked the hospitals. Three years were spent abroad, and then the young student returned to Cambridge to take his medical degree at Harvard, and to deliver his metrical Essay on Poetry, before the Phi-Beta-Kappa Society. In this year too, 1836, he published his first acknowledged book of poems,--a duodecimo volume of less than two hundred pages. In this collection his Essay on Poetry appeared. It describes the art in four stages, _viz._, the Pastoral or Bucolic, the Martial, the Epic, and the Dramatic. In illustration of his views, he furnished exemplars from his own prolific muse, and his striking poem of "Old Ironsides" was printed for the first time, and sprang at a bound into national esteem. And in this first book, there was included that little poem, "The Last Leaf," better work than which Holmes has never done. It is in a vein which he has developed much since then. Grace, humor, pathos, and happiness of phrase and idea, are all to be found in its delicious stanzas:-- I saw him once before, As he passed by the door, And again The pavement stones resound, As he totters o'er the ground With his cane. They say that in his prime, Ere the pruning-knife of Time Cut him down, Not a better man was found By the Crier on his round Through the town. But now he walks the streets, And he looks at all he meets, Sad and wan; And he shakes his feeble head, That it seems as if he said, "They are gone!" The mossy marbles rest On the lips that he has prest In their bloom, And the names he loved to hear Have been carved for many a year On the tomb. My grandmamma has said-- Poor old lady, she is dead Long ago-- That he had a Roman nose, And his cheek was like a rose In the snow. But now his nose is thin, And it rests upon his chin Like a staff; And a crook is in his back, And a melancholy crack In his laugh. I know it is a sin For me to sit and grin At him here; But the old three-cornered hat, And the breeches, and all that, Are so queer!
