xcviii Appendix A. 
1827 . Additional testimony respecting the Sea Serpent of 
the American Seas. Edinb. Journ. Nat. Sc. vi (182 7), p. 126. 
Consists of two evidently veracious accounts submitted to my 
father at second hand, of what the spectators believed to be 
sea-serpents, but which, as it appears to me, may have been 
shoals of porpoises. 
Mnscologia Britannica, second edition. Corrected and 
enlarged, with thirty-six plates and 378 species, including the 
Hepaticae which were not included in the first edition. 
1828 . Appendix to Parry’s * Fourth Voyage, An Attempt to 
reach the North Pole,’ 4to ; the species enumerated are eighty- 
eight from Spitzbergen, and forty-four from Hammerfest. 
Curtis’s Flora Londinensis, new edition 1 , by Thomas 
Graves, F.L.S., in five vols. folio, with 666 plates, coloured, was 
in this year brought to an abrupt conclusion. This magnificent 
work taxed my father’s time and artistic skill for ten years. 
Owing to incredible mismanagement on the part of the Editor, 
it never took the position in botanical literature which the excel- 
lence of the descriptions and beauty of the plates merited. The 
main cause of this was that (as in the case of the first edition), 
the plates not being numbered or referred to in the letter-press, 
which itself was not paged, citation was impossible. Further- 
more, the title of the second edition is a misnomer ; that of the 
first was * Flora Londinensis, or Plates and Descriptions of such 
Plants as grow wild in the Environs of London ’ ; that of the 
second is ‘ Flora Londinensis, containing a History of the Plants 
indigenous to Great Britain/ Neither edition has either Preface 
or Introduction, and the plates of the first bear no artist's signa- 
tures ; they are no doubt by William Curtis himself, whose name 
on the title-page of the work is a guarantee for their truth 
and beauty. The accompanying descriptions are meagre. In 
the new edition the plates of vols. i-iii (443) are reprints from the 
coppers used in the first, and are of plants found in the environs 
of London ; those of vols. iv and v are of plants very few indeed 
of which are indigenous anywhere near London. Of these, 
1 The first edition was in two small folio volumes, with 434 coloured plates, 
published 1777-1787.
