His Majesty, fixed Mr. Bauer in that capacity at Kew, himself de- 

 fraying the salary during his own life, and providing by his will for 

 its continuance to the termination of that of Mr. Bauer. In fulfil- 

 ment of this engagement with Sir Joseph, Mr. Bauer made numerous 

 drawings and sketches of the plants of the garden, which are now 

 preserved in the British Museum. A selection from his drawings 

 was published in 1796 under the title of ' Delineations of Exotick 

 Plants cultivated in the Royal Garden at Kew,' and this was in- 

 tended to be continued annually ; but no more than three parts, con- 

 sisting 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 after- 

 wards, were published in the 11th volume of our Transactions, 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 

 our Transactions is enriched with his elaborate drawings accom- 

 panying 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 draviings 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 mici'oscopic investigation. The sub- 

 ject 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 observations on the Vibrio Tritici of 

 Gleichen, with the figures relating to them ; and another small por- 

 tion of his illustrations of the Diseases of Corn has since been pub- 

 lished by him in the ' Penny Magazine' for 1833. His figures of a 

 somewhat analogous subject, the Apple-blight and the Insect produ-
