698 THE POPULAR SCIENCE MONTHLY. 



Ludwig Schkuhr, of Wittenberg, an eminent cryptogamist ; Pro- 

 fessor and Medical Counselor Heinrich Adolph Schrader, of 

 Gottingen ; Kurt Sprengel, professor of medicine and botanist at 

 Halle ; and Prof. Olof Swartz, one of Linnseus's most eminent 

 pupils. Among the twenty-eight home correspondents mentioned 

 by Muhlenberg in the preface to his catalogue are the Rev. Chris- 

 tian Denke, of Nazareth, Pa., the Rev. Samuel Kramph, of North 

 Carolina, the Moravian bishop Jacob Van Vleck, and Dr. Chris- 

 topher Muller, of Harmony, Pa. One of the most valued was Dr. 

 Baldwin, of South Carolina, and Muhlenberg's letters to him have 

 been published by William Darlington, in a volume entitled Bald- 

 winiana. All or nearly all these correspondents were entertained 

 by him in his home at Lancaster, which was open to all students 

 of plants, and was usually visited by them when they came to 

 Philadelphia. Alexander von Humboldt and Aims' Bonpland 

 sought him there on their return from their long sojourn in Span- 

 ish America ; and Humboldt's letter acknowledging his hospital- 

 ity is the last which that master in science wrote in America. 



Learned societies and institutions likewise covered him with 

 their honors. The University of Pennsylvania gave him the de- 

 gree of Master of Arts in 1780 ; Princeton College, that of Doctor 

 of Divinity in 1787. He was elected a member of the American 

 Philosophical Society on January 22, 1785, along with Joseph 

 Priestley and James Madison. Of other societies he received 

 diplomas: from the Imperial Academy of Erlangen, 1791; the 

 Society of Friends of Natural History, Berlin, 1798 ; the Westpha- 

 lian Natural History Society, 1798 ; the Phytographic Society of 

 Gottingen, 1802; the Physical Society of Gottingen, 1802; the 

 Linnsean Society of Philadelphia, 1809 ; the Academy of Natural 

 Sciences of Philadelphia, 1814 ; the Society for the Promotion of 

 the Useful Arts, Albany, N. Y., 1815 ; the Physiographical So- 

 ciety of Lund, Sweden, 1815; and the New York Historical So- 

 ciety, April 12, 1815, not quite six weeks before his death. 



Introducing the description of a Muhleribergia, in the second 

 volume of his work on the Grasses, Prof. Schreber wrote : " The 

 genus of which this remarkable grass is on account of its beauty 

 and of the particularly curious structure of its organs of fructifi- 

 cation one of the most notable species, received its name from me 

 when I published the new edition of the Genera Plantarum of 

 the honored Linnaeus, after my most revered friend Dr. Heinrich 

 Muhlenberg, evangelical preacher at Lancaster, Pennsylvania, and 

 President of Franklin College there, and also an eminent member 

 of many learned societies ; who has, through the discovery of nu- 

 merous new species and in other ways, rendered immortal service to 

 the natural history of North America, and especially to the knowl- 

 edge of the plants of Pennsylvania and the other United States."
