Reverting to the descendants of Professor James Gregorie—the son, grandsons, great-grandson, and great-great-grandsons, were founders or builders, all of them of medical education in Scotland, each doing his own part for the cause of medicine. James the son, called the third professor of that name (for one of his mathematical cousins was the second), was recognised and honoured as ‘the founder’ of the Medical School at Aberdeen, though the foundations indeed must lie very deep, for by no amount of digging can traces of them be discovered. Professor John the grandson (his half-brother, Professor James the fourth, was inconsiderable), the fellow-worker with Cullen, accepted and taught that great doctor’s views, and with his charming good-sense eradicated many of the more prejudicial items of children’s upbringing. The great-grandson, Professor James (the fifth), more than took his father’s place as a teacher, and setting the medical world of Edinburgh at defiance, made one of the most sweeping reforms that has ever taken place in the history of clinical teaching in that university. He was also one of the great leaders in the volunteer movement. The great-great-grandsons, Professor William Gregory and Professor William Pulteney Alison, were professors both of them in the Medical Faculty of the Edinburgh University, and taught their subjects in the lucid and original way, which was the gift of the whole family. Duncan Farquharson Gregory was the only one of the descendants of James Gregorie, the great contemporary of Newton, who followed in his footsteps as a mathematician. He died in his thirtieth year, but left behind him a brilliant record of his life’s work, which is only sad because it was so short.
