90 MEMOIR OF THE LATE FRANCIS BAUER. 



parts, consisting wholly of Heaths, and containing thirty plates, were 

 published. 



In the early part of 1801, Mr. Bauer made for Mr. Brown, who had 

 then been for some years engaged in a particular study of the Ferns, 

 drawings of many genera of that family which Mr. Brown regarded as 

 new. His drawings of Woodsia, made some years afterwards, were 

 published in the llth volume of our Transations, in illustration of Mr. 

 Brown's paper on that genus. At a later period he again directed his 

 attention to that tribe of plants, his labours in which have within these 

 few years been given to the world in Sir William Jackson Hooker's 

 " Genera of Ferns." The 13th volume of the Linnsean Transactions is 

 enriched with his elaborate drawings, accompanying Mr. Brown's 

 memoir on Rafflesia ; and the part published last year contains a 

 paper by Mr. Bauer " On the Ergot of Rye," from materials collected 

 between the years 1805 and 1809. 



The plate which accompanies the last-mentioned paper is derived 

 from drawings which form part of an extensive series in the British 

 Museum, illustrative of the structure of the grain, the germination, 

 growth and development of wheat, and the diseases of that and other 

 Cerealia. This admirable series of drawings constitutes perhaps the 

 most splendid and important monument of Mr. Bauer's extraordinary 

 talents as an artist and skill in microscopic investigation. The subject was 

 suggested to him by Sir Joseph Banks, who was engaged in an inquiry 

 into the disease of Corn known under the name of " Blight," and the part 

 of Mr. Bauer's drawings which relates to that disease was published in 

 illustration of Sir Joseph's memoir on the subject, and has been several 

 times reprinted with it. Mr. Bauer has himself given, in the volume 

 of the " Philosophical Transactions" for 1823, an account of his obser- 

 vations on the Vibrio Tritici of Gleichen, with the figures relating to 

 them ; and another small portion of his illustrations of the Diseases of 

 Corn, has since been published by him in the " Penny Magazine" for 

 1833. His figures of a somewhat analogous subject, the Apple-blight, 

 and the insect producing it, accompany Sir Joseph Banks's Memoir on 

 the Introduction of that Disease into England, in the 2nd volume of 

 the " Transactions of the Horticultural Society." 



Before the close of the last century, Mr. Bauer commenced a series 

 of drawings of Orchidece, and of the details of their remarkable struc- 

 ture, to which he continued to add, as opportunities offered, nearly to 

 the termination of his life. A selection from these, which form one 

 of the most beautiful and extensive series of his botanical drawings, 

 was lithographed and published by Professor Lindley between the
