medium height, his person stout with a sHght stoop, and 

 his walk peculiar and mincing, resembling that of an 

 Indian." * 



Nuttall returned to England in December, 1841, where 

 he resided for the remaining seventeen years of his life. 

 An uncle who had prospered in business, having no family, 

 left to him an estate called Nutgrove, in the neighborhood 

 of Liverpool. Nuttall, according to the conditions of the 

 bequest, was to reside in England at least nine months of 

 the year. He had been thirty-four years in the United 

 States, so that, although he had visited England in 1811, 

 and in 1822, returning to reside permanently in the land 

 of his birth was a hardship to our much-traveled botanist. 

 He, therefore, hesitated for some time before accepting the 

 new responsibilities, but consideration for his sisters and 

 their families finally induced him to accept the property. 



Shortly before leaving the United States, Nuttall wrote 

 a supplement to Michaux's Silva in three volumes.f The 

 w^ork appeared in 1842-1854. 



Nuttall returned to America, stopping in Philadelphia 

 during the last three months of 1847 and the first three of 

 1848, and while here he studied at the Philadelphia 

 Academy the plants brought by Dr. William Gambel, from 

 the Rocky Mountains and Upper California, and prepared 

 a paper on them which was published in the Journal of the 

 Academy of Natural Sciences.
