E. W. S. LuTwiDGE, Esq., F. R. A. S., Las an original seal with a bead of Sir "William Herschel, 

 ■which is shown on the titli'-page of this work. A cut of it has been courteously furnished me by John 

 Browning, Esq., F. R. A. S., etc. 



In 1787 a bust of Herschel was made by Lockie for Sir William Watson. 



A picture of Heeschel was painted by Mr. Artaud about the beginning of 1810. A portrait of 

 Herschel by Abbott is in the National Portrait Gallery, London. There are no doubt many other 

 p.aintings in England, though I can find notices of those only. The Eoy.al Society of London has nearly 

 a hnndred portraits of its most distinguished members, but owns none of Sir William Herschel.
