THE CONCHOLOGICAL WRITINGS OF CAPTAIN THOMAS BROWN. 
By C. Davies Suerzorn, F.Z.S. 
Read 16th June, 1905. 
Carrain Tuomas Brown is credited with the following works on 
conchology :— 
1. “The Elements of Conchology.” London, 1816. 8vo; pp. viii, 
168, 9 pls. 
(Also advertised as ‘‘speedily will appear” in 1845, but un- 
known to me.) 
2. “Tllustrations of the Conchology of Great Britain and Ireland.” 
Edinburgh, 1827. 4to; text of fly-leaves between the 52 plates. 
In the British Museum (press-mark 443 i 16) are No. 1 
(pls. xviii, xxiii, xxiv, xxxix), No. 2 (pls. iii, iv, vi, viii), No. 3 
(pls. x, xiii, xxi, xxvii), each with accompanying fly-leaves. 
A note in the catalogue says ‘all published,” but perfect copies 
are to be seen in the Bodleian, the British Museum (Nat. Hist.), 
and the Sykes Libraries. There has never been any question of 
the date of this book, so far as I am aware, and we can take it as 
it is dated, 1827. 
2a. Idem, ed. 2. London, 1844. 4to; pp. xiii, 144, 59 pls. Printed 
in double columns. Many figures were added upon the old plates. 
This book presents many difficulties; at pp. 14 and 21 the 
setting of the type alters. It was published in parts, of which 
nothing is known but the following information kindly supplied 
by Messrs. Smith, Elder, & Co., the publishers: ‘‘ We find that 
15 parts of ‘Recent Conchology,’ numbered 1 to 11 and 16 to 19, 
appear to have been issued, and that parts 1 to 4 were received 
by us for sale in 1837 and part 5 in 1839.” In the “ Elem. 
Foss. Conch.” the advertisement says—‘‘ to be completed in 16 
parts (62 pls.), of which 14 are out. 1843.”

11-180, 19 pls.
