THE BOTANISTS OF PHILADELPHIA. 129 



theological studies, he engaged in teaching in the academy 

 at Niesky. He was all this time not only a diligent student 

 of fungi, but scarcely any topic in the wide field of science 

 escaped his notice. So many interesting and new genera 

 and species of fungi had been found by himself and 

 Albertini, that in 1805 a volume of about 400 pages was 

 published by them conjointly, bearing the following title : 

 "Conspectus Fungorum in Lusatise Superioris Agro Nis- 

 kiensi crescentium e Methodo Persooniana. Cum tabulis 

 xii, aeneis pictis, species novas XCIII sistendibus. Auctori- 

 bus J. B. d' Albertini, L. D. de Schweinitz, Lipsise, 1805." 



De Schweinitz engaged in preaching before he left 

 Niesky, and in 1807 he was called to similar work in the 

 Moravian settlement at Gnadenberg, in Silesia. The follow- 

 ing year he was called to Gnadau, in Saxony, and remained 

 there till 1812. At this time he was appointed general agent 

 to his Church in the United States. He married Louiza 

 Amelia Le Doux before leaving, and with his wife was com- 

 pelled, on account of Napoleon's operations to take a route 

 through Denmark and Sweden, in order to embark for this 

 country. This was advantageous to him on account of 

 extending his acquaintance with men of learning. At Kiel, 

 in Holstein, he became known to many professors of the 

 University ; and that institution conveyed upon him the 

 same year, the honorary title of Doctor of Philosophy. 



It was a perilous voyage to make at that time, for the 

 United States had declared war against Great Britain. 

 Besides they encountered terrible storms and their vessel 

 was dismasted. They finally reached the shore in safety, 

 and he began his work to appointment at Salem, N. C. In 

 the meantime, " he found time to prosecute the study of 

 botany in a dominion, scientifically speaking, all his own."
