which occurred. I do not think I gained much from him intellectually; but
his example ought to have been of much moral service to all his children.
One of his golden rules (a hard one to follow) was, 'Never become the
friend of any one whom you cannot respect.'"

Dr. Darwin had six children (Of these Mrs. Wedgwood is now the sole

took the degree of Bachelor of Medicine at Cambridge. He never made any
pretence of practising as a doctor, and, after leaving Cambridge, lived a
quiet life in London.

There was something pathetic in Charles Darwin's affection for his brother
Erasmus, as if he always recollected his solitary life, and the touching
patience and sweetness of his nature. He often spoke of him as "Poor old
Ras," or "Poor dear old Philos"--I imagine Philos (Philosopher) was a relic
of the days when they worked at chemistry in the tool-house at Shrewsbury--
a time of which he always preserved a pleasant memory. Erasmus being
rather more than four years older than Charles Darwin, they were not long
together at Cambridge, but previously at Edinburgh they lived in the same
lodgings, and after the Voyage they lived for a time together in Erasmus'
house in Great Marlborough Street. At this time also he often speaks with
much affection of Erasmus in his letters to Fox, using words such as "my
