John Ralfs was born September 13, 1807, at Millbrook, near Southampton. His father, Samuel Ralfs, died when he was a year old, and to his mother was entrusted his early training. From an early age he manifested a passionate love of flowers, and as he grew older an interest in chemistry. Probably on this latter account he decided on the medical profession, and whilst studying medicine he prosecuted botanical research, so that on passing his final examination the President of the Royal College of Surgeons complimented him on his botanical knowledge, and predicted that the world would one day hear a good deal of this then "beardless boy." He married a Miss Newman, and by her had a son, but they were in every way an ill-suited pair, and after a while they agreed to part, and she went to reside in France, taking her son with her. Fortunately for science, Ralfs' health would not stand the arduous and anxious life of a village doctor, and he threw up his profession and wandered about in the south of England, a friendless, reserved, and taciturn man, devoting all his time and attention to botany. He settled finally in Penzance, in the year 1837, and became a familiar personality in the west of Cornwall, rambling over the moors, creeping into bogs, often on hands and knees, searching for rare plants; "a terror to timid ladies, who would scuttle away like frightened rabbits at the sight of this dark, strange man hanging over some deep pool, peering with his short-sighted eyes into what was to him a paradise, and perhaps calling out aloud, forgetful that he and nature were not alone, 'I see him! I've got him!' And often he would be seen resting on a stile, weary with his wanderings, his hat and coat almost as green as the grass on one of his favourite bogs, the marks of his last fray fresh upon them, his collar disappearing, apparently, in vain search of his cravat; gazing absently into the distance, where he saw, doubtless, beautiful and rare specimens of his Algæ and Diatomaceæ." Mr. Ralfs was never so happy as when alone; he did not care for society, least of all that of women, and grievous deafness made it difficult for him to engage in conversation. Even with men of science like himself he did not care to associate, except through written correspondence. At Penzance he was generally regarded as "a bit total," a little, perhaps not a little, off his head; but no one could have other than a kind word to say of him, for he never injured any one. Occasionally his son came from France to pay his father a visit; but such visits were brief; their tastes were not the same, and their outlook into life was different.
