HCR diary 9.8.1832 "I took Mr hall to see Mrs Aders' pictures - she was there and thus the whole morning - for we went to the Athenaeum - was spent with him. Mrs A: says he has a good taste and knowledge of paintings, tho' his taste is not altogether for the old masters"
24.4.1839 "to Christie's to inspect the pictures. There I met with hall who gives a favourable opinion of them"
26.4.1839 at sale of Aders' pictures "For the great picture there were no bidders but myself thro' Mr Hall and Lemme who for himself took it at 95 gns and but for me it would have gone for nothing" "I bought for £31.10s a great favourite of mine - a Perugino which Hall said I might venture to buy at that sum." "Hare Hall introduced me to Pugin the very able architect and sarcastic author of the contrasts"
"Hare hall" may be a mistranscripion. This was probably Chambers Hall (DNB 1786-1855)
