There is also in the possession of his son, Bishop de Schweinitz, 

 of Bethlehem, Pa., a manuscript work entitled : " Synopsis Fungo- 

 rum Americanorum qui Ludovicus David de Schweinitz innotuere. 

 Secundum Systema Fries." This work is different from No. 10, but 

 whether written before or after is unknown. The manuscript is 

 carefully written in three bound volumes, 8vo. : the first having 116 

 pp., the second 175 pp, the third 100 pp. Some of the pages except 

 the running title on the top are blank and were evidently to be filled 

 out as the researches proceeded. 



Other works, especially monographs were most probably written 

 and remained in manuscript, but there whereabouts are unknown. 



A tabular view, as arranged by Mr. Johnson, of the works named 

 in this bibliography is appended:
