Peter Collinson and to the Royal Society, and afterwards 

 published in a Latin treatise ; which was reprinted by 

 Fothergill in 1747, with a short preface, and an English 

 version. The author's name is preserved in the genus 

 of plants Logania, and the natural order Loganiacece. 

 He died in 175 1. 1 



His son, William Logan, born in 1718, had a legal 

 training, and succeeded his father at Stenton : he was 

 a citizen of repute in Philadelphia, and an influential 

 member of the governor's council from 1747 to 1775, 

 when it was dissolved. Samuel Fothergill found him a

 Pennsylvanian government with some Indian nations.

 Fothergill as pupil to Dr. William Hunter, then in the 

 zenith of his fame as an anatomical teacher ; after which

 invention of the quadrant by Godfrey, in S. Miller, Retrospect of XVIIIth 

 Century, i. 407. His brother, Dr. William Logan (1686-1757), was a physician 

 practising in Bristol. Portraits of Dr. W. Logan and his wife are preserved 

 in Philadelphia, and are reproduced in Hannah Logan's Courtship, by A. C. 

 Myers. A prescription shown at Mr. Wellcome's Historical Medical Museum, 

 London, appears to be his.
