230 MEMOIB OF Mil. W. C. IIEWITSOK, F.L.S., 



He di*ew on stone all the figures of his Lepidoptera by line 

 and rule and compasses with the minutest accuracy, and coloured 

 them from the specimens himself, with extreme delicacy and 

 beauty of execution, having an extraordinarily acute faculty for 

 the appreciation of colour. His work was confined to the exter- 

 nal chai'acters of the Lepidoptera ; into their internal structure, 

 not being an anatomist, he made no researches. 



He was an original member of the I^atural Histoiy Society of 

 Is^orthumberland, Durham, and Newcastle-upon-Tyne, was one 

 of the Honorary Secretaries in 1833-34, and he continued for 

 many years to be a member and honorary Curator, contributing 

 periodically and handsomely to the funds of the Institution. 



In London he became a member of the Entomological Society 

 in 1846, of the Zoological Society in 1859, and of the Linnaean 

 Society in 1862. 



Owing to his generally hypochondriacal condition, and ad- 

 vancing age, about two years before his death he began to decline 

 in bodily healtli. Towards the end of 1877 he became worse, 

 and a surgical disorder came prominently forward, for this he re- 

 fused to be operated on, and died exhausted on the 28th of May, 

 1878, aged 72 years. 



He was inten-ed on June Ist, in the churchyard of "Walton-on- 

 Thames, and a monument of gi'anite was subsequently erected 

 over his remains. 



Mr. Hewitson's will was dated March lOtli, 1878, and there 

 was a codicil dated May 21st, 1878. The provisions in these 

 testamentary documents shew the amiable and charitable bent of 

 his mind, and that his prevalent ideas at the time of their being 

 drawn up, were to do good ^vith his considerable means, and to 

 leave an impression of kindness on the minds of his numerous 

 friends and dependants. The following bequests are contained 

 in the will and codicil : — 



£10,000 to the Newcastle-upon-Tyne Inlinnary. 



£r),000 to the Oq)lian Houses, Ashley Down. Ihislol. 



£3,000 to the London City Mission. 



£3,000 to the Natural History Society of Northumberland, 

 Durham, and Newcastlc-upon-Tyiic.
