of Professor Rauwenhoff, Director of the Archives at Leyden. He quotes
from the catalogue of doctors that "Robertus Waring Darwin, Anglo-
britannus," defended (February 26, 1785) in the Senate a Dissertation on
the coloured images seen after looking at a bright object, and "Medicinae
Doctor creatus est a clar. Paradijs." The archives of Leyden University
are so complete that Professor Rauwenhoff is able to tell me that my
grandfather lived together with a certain "Petrus Crompton, Anglus," in
lodgings in the Apothekersdijk. Dr. Darwin's Leyden dissertation was
published in the 'Philosophical Transactions,' and my father used to say
that the work was in fact due to Erasmus Darwin.--F.D.) at that University
on February 26, 1785. "His father" (Erasmus) "brought ('Life of Erasmus

(1787), and left him 20 pounds, saying, 'Let me know when you want more,
and I will send it you.' His uncle, the rector of Elston, afterwards also
sent him 20 pounds, and this was the sole pecuniary aid which he ever
received...Erasmus tells Mr. Edgeworth that his son Robert, after being
settled in Shrewsbury for only six months, 'already had between forty and
fifty patients.' By the second year he was in considerable, and ever
afterwards in very large, practice."

Robert Waring Darwin married (April 18, 1796) Susannah, the daughter of his
father's friend, Josiah Wedgwood, of Etruria, then in her thirty-second
year. We have a miniature of her, with a remarkably sweet and happy face,
bearing some resemblance to the portrait by Sir Joshua Reynolds of her
father; a countenance expressive of the gentle and sympathetic nature which
Miss Meteyard ascribes to her. ('A Group of Englishmen,' by Miss Meteyard,
1871.) She died July 15, 1817, thirty-two years before her husband, whose
death occurred on November 13, 1848. Dr. Darwin lived before his marriage
for two or three years on St. John's Hill; afterwards at the Crescent,
where his eldest daughter Marianne was born; lastly at the "Mount," in the
