composition, that some parts of his work were set up without a 

 single error, and others even without written copy. 



Not satisfied with his previous labours and risks, Mr. Nuttall 

 in 1818 again left Philadelphia, and, assisted by his friends Messrs. 

 Correa da Serra, Collins, and others, again started upon a long 

 and dangerous expedition to the region of Arkansas and the north- 

 west parts of the American continent. This arduous and perilous 

 journey of more than 5000 miles, in an unexplored country, occu- 

 pied fifteen or sixteen months, and was attended with numerous 

 hardships, privations, and actual dangers to life and health. Ee- 

 turned to Philadelphia, Mr. Nuttall in the following year published 

 his ' Journey into the Interior of Arkansas,' with an Appendix 

 consisting of, — 1st, " An Account of the Ancient Aboriginal 

 Popidation of the Banks of the Mississippi ;" 2nd, " A History of 

 the Natches;" 3rd, "Observations on the Chickasaws and Choc- 

 taws ;" 4th, " Meteorological Observations," — titles alone suffi- 

 cient to show the variety of subjects to which his observations 

 were directed, and the ardent scientific zeal with which he was 

 actuated. 



In 1822 Mr, Nuttall was appointed Curator of the Botanic 

 Gardens at Harvard University, his time being devoted to the 

 culture of rare plants, and to the study of mineralogy and ornitho- 

 logy ; and in 1832 he produced his ' Manual of the Ornithology 

 of the United States and Canada ;' and about the same time 

 appeared his ' Introduction to Systematic and Physiological Bo- 

 tany,' and several other botanical and ornithological works of less 

 importance. In the year 1834 Mr. Nuttall again started on an 

 overland journey to the Pacific, in company with Capt. "Wyeth, of 

 which expedition an account has been published by Mr. Townsend, 

 who formed one of the party, in his ' Narrative of a Journey 

 across the Bocky Mountains to the Columbia River,' &c. 



Prom Vancouver's Island, the party proceeded to the Sandwich 

 Islands, whence Mr. Nuttall returned to California, where he 

 remained during great part of the spring and summer, and again 

 proceeding to the Sandwich Islands, finally returned to the United 

 States by way of Cape Horn. After his return to Philadelphia 

 he seems to have devoted much attention to Conchology. 



Shortly after this period Mr. Nuttall came to England on having 

 some property bequeathed to him by a relative ; and, compelled by 

 a curious, and to him, doubtless, an oppressive proviso in the vrill, 

 which obliged him to reside for a certain time every year upon his 

 property, he only once revisited, for a few months, his adopted
