In 1787 a bust of Hekschel was made by LocKn: for Sir Tyiu.iAJi Watson. 



A picture of IIekschei. was painted by Mr. Artaud about the beginning of 1819. A portrait of 

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

 paintings in England, thougli I can find notices of these only. The Eoyal So(dety of London has nearly 

 a hundred portraits of its most distinguished members, but owns none of Sir Williaji Ueuscuel.
