Cases 2 to 12 were of several families in one house in a court in Long Lane, Aldersgate Street, who had been infected by a discharged prisoner from Newgate. Other cases follow, where the infection was caught from visiting the sick. In Case 17, Lettsom applied blisters “owing to the importunity of the friends,” but without advantage. Case 30, on 26th October, 1773, was of a family of six persons near Christ Church, Lambeth, father, mother, boy of seventeen, child of two (slight attack) and two maids. Other localities were courts off Whitecross Street, Jewin Street, Little Moorfields, Chiswell Street, and St Martin’s-le-Grand. Case 43 was of a woman, aged thirty, in Bunhill Row; she attended a relation who died of a putrid fever, and was herself attacked; her eyes were bloodshot, her skin marbled and interspersed with a general deep-coloured eruption, her cheeks and nose mortified. Cases 44-47 were of people in a “very helpless situation” in Gloucester Court, Whitecross Street. The year 1773, to which these experiences in a small part of London relate, was one of high febrile mortality, according to the Bills. Two years after, Dr William Grant was moved to write an ‘Essay on the Pestilential Fever of Sydenham, commonly called Gaol, Hospital, Ship and Camp Fever[244],’ which, as he said in his preface, “I often see in this city: and though so common and fatal, appears not at present to be generally understood.” It was, he says, “an indigenous plant, frequent in this city, being produced by close confinement; but it often passes unnoticed, because unknown.” The deaths by “fever” in the London Bills were as follows until the end of the century: _Deaths from Fever and from all causes in London._ Fever All Year deaths deaths 1771 2273 21780 1772 3207 26053 1773 3608 21656 1774 2607 20884 1775 2244 20514 1776 1893 19048 1777 2760 23334 1778 2647 20399 1779 2336 20420 1780 2316 20517 1781 2249 20719 1782 2552 17918 1783 2313 19029 1784 1973 17828 1785 2310 18919 1786 2981 20454 1787 2887 19349 1788 2769 19697 1789 2380 20749 1790 2185 18038 1791 2013 18760 1792 2236 20213 1793 2426 21749 1794 1935 19241 1795 1947 21179 1796 1547 19288 1797 1526 17014 1798 1754 18155 1799 1784 18134 1800 2712 23068
