Barratt, Torrey and Schweixitz: a Correction and a Dis- 

 crepaxcy — Mr. C. L. Shear, one of the editors of the recently pub- 

 lished correspondence of Schweinitz and Torrey (Mem. Torr. Bot. 

 Club, xvi. no. 3, July, 1921) has called my attention to a discrepancy 

 between a statement in my paper on Joseph Barratt (Rhodora 

 xxiii. 123) and one of Torrey 's letters. I said that Barratt, in com- 

 pany with Torrey, visited Schweinitz at Bethlehem in the autumn 

 of 1825. There is not only no mention of such a visit in the cor- 

 respondence, but in a letter dated "December — 1825," Torrey writes 

 to Schweinitz, "I am greatly rejoiced to hear, through our friend 

 Mr. Halsey, of your safe return after so tedious an absence." The 

 tedious absence was a trip to Europe which Schweinitz made in the 

 spring and summer of 1825: Torrey could hardly have said in De- 

 cember that he had learned of Schweinitz's return through a third 

 person if he had seen him in the autumn. 



Through the kindness of Mr. John H. Sage, I have had the priv- 

 ilege of re-examining Barratt's ajtobiographical memoranda. These 

 show that that part of my statement placing the meeting with 

 Schweinitz at Bethlehem was based on a misreading of Barratt's 

 rather crabbed manuscript. He wrote, "Saw Mr. Schweinitz of
