[9] Biberg was a Swedish naturalist and had studied botany under Linnaeus in Uppsala; Réaumur, a French botanist, had contributed papers to the _Philosophical Transactions_ of the Royal Society in London.
[10] _The Power of Water-Dock against the Scurvy whether in the Plain Root or Essence...._ (London, 1765), had been published six months earlier than _Hypochondriasis_ and had earned Hill a handsome profit.
[11] I have treated aspects of this subject in my article, "Matt Bramble and The Sulphur Controversy in the XVIIIth Century: Medical Background of _Humphry Clinker_," _JHI_, XXVIII (1967), 577-90.
[12] See, for example, Jeremiah Waineright, _A Mechanical Account of the Non-Naturals_ (1707); John Arbuthnot, _An Essay Concerning the Effects of Air on Human Bodies_ (1733); Frank Nichols, _De Anima Medica_ (1750).

[15] It is difficult to know with certainty when Hill first became interested in the herb. He mentions it in passing in _The British Herbal_ (1756), I, 526 and may have sold it as early as 1742 when he opened an apothecary shop.
[16] Reid's dissertation at Edinburgh, entitled _De Insania_ (1798), contains materials on the relationship of the imagination to all forms of mental disturbance. Secondary literature on hypochondria is plentiful. Works include: R. H. Gillespie, _Hypochondria_ (London, 1928), William K. Richmond, _The English Disease_ (London, 1958), Charles Chenevix Trench, _The Royal Malady_ (New York, 1964), and Ilza Vieth, _Hysteria: The History of a Disease_ (Chicago, 1965), and "On Hysterical and Hypochondriacal Afflictions," _Bulletin of the History of Medicine_, XXX (1956), 233-40.
