."304 SHEPPARD : MARTIN SIMPSON AND HIS GEOLOGICAL MEMOIRS 
greatly to the establishment of Pliilosophical Institutions and Museums, 
which the great wealth and the national prosperity of the present era 
scarcely sustain." 
Reference is made to Yomig & Bird's " Geological Survey of the 
Yorkshire .Coast " (1822), to the work of Bean and Williamson, John 
Phillips's "lUitstratioiL^ ot the Geology of Yorkshire" (1st edition, 1829), 
and the formation of the museums at Scarborough and Whitby. He 
states that he was lecturer to the Whitby Society, and curator of its 
]\Iuseum in 1837, that he published his " Ammonites of the Yorkshire 
Lias " in 1843, and, in 1855, his descriptions of all the then known 
fossils of the Yorkshire Lias, together with an outline of the Geology 
of the Yorkshire Coast."* 
As a fine piece of early zonal collecting, we may quote the tollowingi • 
" Being convinced by observation that few species of the Lia^ 
fossils had existed during the deposition of any great thickness of 
strata, but, on the contrary, were often confined to thin seams, I 
measured carefully, with a two feet rule, all the beds and seams of 
Lias, };oth to the south and north of Whitby, and at the same time 
collected the fossils from each stratum. This section T published in 
1 868, in the fourth edition of nw ' Guide to the Geolog\'^ of the Yorkshire 
Coast.' This section I now reprint (pp. ix. — xxiii.), with sliG:nt 
alterations, and to which the fossils in the catalogue are referred.'* 
He then refers to Tate & Blake's work on " The Yorkshire Lias." 
" As they [Tate & Blake] expressed their intention to recognise and do 
justice to my previous researclies and publications, I willingly laid 
open to them what I had been accumulating towards the further 
illustrations of our Lias. Their work was published in 1876 ; . . 
and the scrupulous fidelity and honour with which they have treated 
my labours gives me the highest gratification." { 
* Apparently this is considered to be the first edition of his " Guide 
to the Geology of the Yorkshire Coast," the second edition of which 
v\^as issued in 1856.

J The references to Simpson's work, by Tate and Blake, are (in the 
Preface), '' We think we ought especially to aclaiowledge the kindness 
of ]Mr. Simpson, the Curator of AMiitby Musemn, who has permitted 
us to examine his types, though we have often thereby come to a 
different opinion as to their interpretation " ; and (on p. 9), 1865-8, 
Mr. Simpson published, in a small handbook called ' A Guide to the 
Geology of the Yorkshire Coast,' ' A Section of the Yorkshire Lias,' as 
seen between Whitby and The Peak. Its chief value is its localizing 
the various fossils before-named by the author. It consists of a
