This eminent botanist died in September last, at his residence near Liverpool, England, at the age (we believe) of 73. Mr. Nuttall rendered great service to American botany; being most eminently an enthusiast of the science, be came to this country the year Michaux left it, and, traversing Upper California and Oregon, completed the great work on trees of the former laborers Michaux, father and son, and his additions are now embodied in the same set of five volumes. Mr. Nuttall was originally a printer; during bis residence among us he lived in a most economical manner from necessity. A relative bequeathed him a good place and garden in England on condition that he should reside upon it six months of each year. Here he employed himself in botanical pursuits, principally in hybridizing the Himalayan Rhododendrons, and to his zeal the great dealers were much indebted. In his tastes Mr. Nuttall was simple and inexpensive; he has left a name which will last as long as flowers are loved.
