ment nor does he state where the third set may be found. 
Possibly the set in the British Museum (which seems to be in- 
complete) was that used by Buchanan jin illustrating his 
‘Gangetic Fishes’, and was the third, the other sets being in 
India House and in Calcutta. 
Cantor (1849) says in his preface (p. xi) that Valenciennes 
had through Horsfield access to Buchanan's drawings in the 
Library of the East India House, London. However, on p. vi 
of the ‘avertissement’, of vol. IV of Cuvier and Valenciennes, 
we read that while Horsfield showed Valenciennes Finlayson’s 
drawings of Siamese fish in the East India House, Gray showed 
him in the Hardwicke Collection the Buchanan drawings of 
fishes described but not figured in the ‘Gangetic Fishes.’ 
For the major part of our knowledge of the fate of Bucha- 
nan’s scientific remains we are indebted to the initiative of 
Francis Day. In 1871 he examined the folio volumes of draw- 
ings and manuscripts of Dr. Buchanan on deposit in the li- 
brary of the Asiatic Society of Bengal in Calcutta. In two of 
these he found “ one hundred and forty-nine original coloured 
delineations of fish and forty-five copies.’’ And he quotes 
ormer “the specific names in Dr. Buchanan's handwriting 
[are] marked under the figures, so as to leave no doubt or 
difficulty in referring them to corresponding descriptions in the 
‘Gangetic Fishes.’ ” McClelland, it will be recalled, in refer- 
ring to these, says that he also found 2 quarto volumes o 
Manuscripts, but Day, however, makes no mention of these. 
Uses MADE oF BucHANAN’S DATA. 
Having given all the information obtainable as to the fate 
of Buchanan’s collections, manuscript notes, and drawings, let 
us now take up an investigation of the use made of his various 
data, particularly that relating to fish and fisheries.
