^04 Account of the late Mi\ William Martin, F,L. S. [J^n. 1; 
hereafter be discriminated.’^ Till ^Ir, 
?>I. published his ‘‘Outlines” no deter¬ 
minate principle for the division of c-x- 
traiienus fossils into species had been 
established, or even proposed. In every 
system that had then appeared, “ the 
Species,” he observes, “ are without order 
and consistency, formed according to the 
caprice or convenience of the writer, 
and characterised by every possible 
affection of which these bodies are sus¬ 
ceptible.” Preface p. 12. 
As an appendix he has annexed “ a 
Systematic Arrangement of the Petrifac¬ 
tions described in the first volume, with 
additional remarks on some of the spe¬ 
cies.” We here find the order, genus, 
and family, to which each species be¬ 
longs; the specific character and name; a 
reference to one or more of his own 
figures; the English name; the seat or 
strata; and the particular place where it 
is found; with an account of the differ- 
fiice? observable in the specimens. 
Nothing scarcely is omitted except the 
synonyms; and it was his intention, if 
Providence had allotted him life and 
health, to publish another volume of the 
work under con-^ideratidn, to give at the 
end of Jt, in one general view, a syste¬ 
matic arrantretnent ot all the species that 
had then been described by him, with 
their synonyms, refeie-ices to the figures 
cf ocher writers, and such additional re- 
marks on each as furtner researcli might 
have enabled him taniake. 
About a year before he was elected q 
member of the Literary and Philosophi¬ 
cal Society of Manchester, he hail pro- 
mioed IP. Hull to send one or more pa¬ 
pers to the society. One of these, enti¬ 
tled “Cursory Pemarks on the iMineral 
Substance called in Derbyshire Rotten- 
Stone,” has been received and read since 
bis death. It was the last thing he 
-wrote, and it is to be regretted that he 
had not entirely completed this paper. 
In a note to tlie “-Outlines,” p. -!40, Air. 
M. sav?, “the Rotten-scoi.e of Derby¬ 
shire is evldeiUiV produced by the disin¬ 
tegration of our black limestone, or mar¬ 
ble, above which it is deposited, not over 
coal, as Gmelin, we know not from what 
autlioritrv, has asserted, 6cc.” And the 
principal part of lids paper appears ffom 
one of his manuscripts to have been ori¬ 
ginally written as a continuation of the 
note just auoied. 
c/ i _ , 
Of another paper, on the Formation of 
the Pipe-veins of Derbyshire, intended 
fi r the same Society, no traces are to be 
faur d ; yet it appears, from a letter which 
Dr. Hull received from hiiii; that it was 
written at the time he was engaged in 
priiiting the “ Outlines.” He says, “ I 
um sorry it lias not been in my power to 
transcribe the paper for the Manchester 
Society ere thi)^, but I find I shall have 
a small drawing or two to make, in ex¬ 
planation of what I advance in it, and A 
doubt it will not be possible for me to 
do this before the vacation, vvhen I hope 
to liave a little more time on iny hands.” 
He left also a letter, only in part 
transcribed, which is addressed to r\Ir. 
Tilioch, and was intended for publication 
in the Philosophical Magazine. 
Mr. M. had made considerable pre¬ 
paration for publishing a Section of the 
Earth, and some Ivlineralogical Maps, 
which, he conceives, would be very ac¬ 
ceptable to geologists and mineralogists, 
and prove profitable to himself. 
In October 1809, he intimated .to his 
friend, the Rev. James Ciimmiiig, fellow 
of Trinity-college, Cambridge, his inten. 
tion to beg permission to take drawings 
from the Woodwardiarr collection of 
fossils. This scheme he hoped to be 
able to execute without its interfering 
with his business as a drawing-master; 
thinking that he could visit Cambridge, 
for the purpose of taking the drawing'^, 
and writing the desciiptions, of the spe¬ 
cimens, in the vacations, and engrave 
the plates at home at his leisure. Mr. 
Gumming very kindly communicated IMr. 
Martinis intention to Prolessor Hail¬ 
stone, who mentioned it to the Wood- 
wardian Syndics, and it was concluded, 
that the work should be an University 
publication, that the whole of the letter- 
press should be written by the Wood- 
vvardian Professor, and tliat Mr. M. 
should receive three guineas for drawing 
and engraving each plate, with a further 
compensation for coloring the plates, 
which iniaht be done by his own family, 
or in the way most convenient and agree¬ 
able to him. It was supposed, that 
forty-five or fifty plates would be suffi¬ 
cient to contain the whole of tiie fossils 
in this collection, worthy of publication, 
which have not already been figured. 
Before thus agreement was made, Mr. 
IMartin had communicated to his, very 
valuable fiiend, Mr. Mills, of Dubhn, 
formerly of Macclesfield, his desire to 
obtain permission to draw and describe 
the petrifactions in the Leskean Museum, 
which Mr. IMi Is and General Vallancey 
gave him reason to hope tliere would l>e 
no doubt of his obtaining, it he should 
determine upon the undertaking. The 
General, at the same time, very politeiy 
requested his acceptance of a copy of
