-rits nor inclination to attend to It. Yet I ought to do 
fo, if poflible ; for that and my other work will be nil, 
perhaps, that a wife and fix helplefs children will have to 
•depend on, for a time, for fubfiftence.” Unfortunately, 
this was but too foon verified. The work to which he 
■ here alludes, as being in the prefs, he was enabled to pub- 
lifh in the beginning of March 1809, under the title of 
Outlines of an Attempt to eftablifh a Knowledge of 
Extraneous Fofiils on fcientific Principles.” Notwith- 
ftanding the modefty of the title, it is truly a claflical pro- 
duftion, which will be found extremely ufeful to perfons 
entering upon the liudy of geology and extraneous fof- 
fils, and will be read with fatisfaftion and advantage by 
thofe who have made confiderable proficiency in thefe de¬ 
partments of mineralogy. When Mr. M. firlt began to 
oolleft and defc'ribe the fofllls that have the form or 
Itrudture of animal or vegetable bodies, and, indeed, till 
this work appeared, we had no elementary book, contain¬ 
ing a regular expofition of fafts and principles on which 
this ftudy could be conducted, as in other branches of 
natural hiftory. Having felt greatly the want of fuch an 
introduffory treatife, and aware of the importance of the 
talk, he fpared no pains to lupply the deficiency, and to 
render the fcier.ce as eafy and inviting to future ftudents 
as it was in his power to effect. In the firft part of the 
work, to which he has given the title of “ An Elementary 
Introduflion to the Study of Extraneous Fofiils, &c.” af¬ 
ter giving definitions of natural bodies, he points out the 
kinds, phenomena, and origin, of relics, with their intro¬ 
duction into the mineral kingdom; their diftinctive cha¬ 
racters, with an explanation of the terms ufed; their geo¬ 
graphic fituation; the principles of their arrangement and 
nomenclature, and the delineation of relics, illuftrated by 
feveral examples. In the body of this part of the work 
he has given the fafts and inferences which conftitute the 
bafis of his ftudy, in diltinft propofitions; and has added 
to thefe fuch obfervations as he deemed neceftary for the 
illuftration of them. In the form of notes will be found 
the more foreign remarks on chemical, mineralogical, and 
geological, fubjefts, with references to authors, lifts of 
zoological terms, &c. from which the ftudent will derive 
much ufeful information, condenfed into a very narrow 
compafs. The fecond part is entitled “ Syltema-Reliquio- 
rum, or an Arrangement of Extraneous Fofhls, as far as it 
refpefts their Orders, Genera, and Families;” and is writ¬ 
ten entirely in the Latin language. The orders and ge¬ 
nera, of which he has given a view in the fir 11 number of 
the Petrificata Derbienlia, differ very materially from thofe 
he finally adopted in this volume. Speaking of the execu¬ 
tion of this work, he has exprefled himfelf in the following 
modeft terms s “ At a diftance from extenfive collections 
and valuable libraries, thofe neceftary helps to the naturalifl 
when writing, my time is almoft wholly taken up with 
the duties of my profeflion, and debarred, by local fitua¬ 
tion, from that perfonal intercourfe with the fcientific 
which might fo materially have aided me in my purfuit; 
this work is truly the production of one who has poflefled 
few advantages for its completion, none indeed except 
thofe which havearifen from a long refidence in a mining- 
country, where the objeCts of the ftudy abound, and have 
been conftantly examined under their mod interefting re¬ 
lations. Hence I beg leave to add, that a large portion 
of the fafts advanced in this treatife has been repeatedly 
confirmed'by my own obfervations. Thefe facts, lam 
aware, are often rudely explained, and fometiir.es inarti- 
ficially put together; but I trult the errors and deficien¬ 
cies of the work will not be found fo numerous as-to pre¬ 
vent its being confidered a proper collection of data for 
the ftudent to proceed on. Hereafter, perhaps, fome one, 
with ledfure and abilities equal to the talk, may conde- 
fcend to fill up thefe Outlines, or, fketching others with 
n happier hand, give to the world a complete Philofophia 
Reliquiorum.” This work was very favourably fpoken 
of in the Antijacobin Review : “ Mr. Martin has rendered 
an important iervice to fcience and the lovers of geologi-

cal ftudies; and his concific, yet copious and portable^ 
work, is the moft ufeful thing of the kind that has yet 
been publiflied. A book-maker would have extended its 
contents over a quarto volume, and then have contrived 
to have charged his readers four times the price for it.” 
Antij. Rev. May 1809. 
In a fhort time after the publication ftf his Outlines, 
Mr. Martin was elefted a Correfponding Member of the 
Literary and Philofophical Society of Manchefter, and an 
Honorary Member of the Geological Society of London. 
In the courfe of the fame year he publiflied the firlt vo¬ 
lume of “ Petrificata Dcr'oienjia, or Figures and Defcrip- 
tions of Petrifactions collected in Derbyfhireand dedi¬ 
cated it by permiflion to fir Jof'eph Banks. This volume 
contains the whole of the work which he began to pub- 
lifh in numbers, but defifted when he had publiflied the 
fifth. It had, however, received many additions and im¬ 
provements. The plates for the illuftration of this work, 
are fifty-two. The figures were all drawn by himfelf; the 
etchings were alfo entirely executed by his own hand, 
and are fufficiently finiflied, though he has been induced 
to apologize for their wanting a certain neatnefs and uni¬ 
formity, on the ground of his not being an engraver by 
profeflion. In colouring the plates he was aflifted by his 
wife, whom he had inftrufted previoufly to his marriage. 
About a year before he was elefted a member of the Lite¬ 
rary and Philofophical Society of Manchefter, he had pro- 
mifed Dr. Hull to fend one or more papers to the fociety. 
One of thefe, entitled “ Curfory Remarks on the Mineral 
Subftance called in Derbyfliire Rotten-Stone,” has been re¬ 
ceived and read fince his death. It was the laft thing he 
wrote. He had made confiderable preparation for publifii- 
ing a SeCfion of the Earth, and fome Mineralogical Maps, 
which, he conceived, would be very acceptable to geolo- 
girts and mineralogifts, and prove profitable to himfelf. 
In OCtober 1809, he intimated to his friend, the Rev; 
James Cumming, fellow of Trinity-college, Cambridge, 
his intention to beg permiflion to take drawings from the 
Woodvvardian collection of fofiils. This fcheme he hoped 
to be able to execute without its interfering with his bu- 
finefs as a drawing-matter; thinking that he could vifit 
Cambridge, for the purpofe of taking the drawings, and 
writing the deferiptions, of the f'pecimens, in the vaca¬ 
tions, and engrave the plates at home at his leifure. Mr. 
Cumming very kindly communicated Mr. Martin’s in¬ 
tention to profeflor Hailttone, who mentioned it to the 
Woodwardian fyndics; and it was concluded, that the 
work lhould be an univerfity-publication, that the whole 
of the letter-prefs fhould be written by the Woodwardian 
profeflor, and that Mr. M. fhould receive three guineas 
for drawing and engraving each plate, with a further 
compenfation for colouring the plates, which might be 
done by his own family, or in the way moft convenient 
and agreeable to him. It was fuppofed, that forty-five or 
fifty plates would be fufficient to contain the whole of 
the fofiils in this collection, worthy of publication, which 
have not already been figured. Mr. Cumming wiftied 
Mr. Martin to be in Cambridge in June or July, that he 
might have an opportunity of introducing him, and ren¬ 
dering him other fervices on his arrival; but, juft as the 
time arrived, viz. on the 31ft of May, 1810, Mr. Martin 
breathed his laft. 
Mr. Martin was below the middle fize, of a flender form 
and delicate appearance, even in his bell health. Ia his 
manners he was' unaffeCted and dilfident; fo modeft in¬ 
deed, that, unlefs he had been initiated as an after in his 
childhood, it is fcarcely conceivable he would ever have 
ventured upon the ftage. His life was marked by none 
of the eccentricities and adventures which fo generally 
charafterife the gens de theatre 5 and his moral charafter 
was irreproachable. In all the relations of a fon, a huf- 
band, and a father, his conduft was truly amiable and 
exemplary. All his hours were devoted to the entertain¬ 
ment or inftruftion of the public. As a comedian, he ex¬ 
celled in the reprefentation of foppifii characters. As a
