form; and to the Essay itself, those who desire to see M.
L a m o u k o u x ’s views in detail, are referred. An excellent
account also of this system, along with an equally excellent
general Essay upon Marine inarliculated Algoe, excluding the
U lv a c e æ , may he found in the Edinhurgli Eneyclopædia,
under the word F u d ,— -M\ article contrihuted hy my much
valued friend Mr P. N e i l i . . Professor A g a r d h , ol Lund, in
Sweden, succeeded the French Algologist, in his Synopsis
Algarmn Scandinavioe, adjecta dispositione universali Algarum :
a work which has heeu since followed hy his more im])ortaiit
Species Algarum and Systema Algarmn. Of these works, the
least that can he said is, th a t they are more perfect, and contain
a greater mass of information and research, than is to he
found in any other publication on the same subject, and they
must ever deserve to retain an eminent place iu the algological
library. A g a r d h has followed the grand outline
chalked out by L a m o u r o u x , hut differs widely from him in
the constitution of his genera, which are formed upon infinitely
more philosophical principles.
Two years subsequently' to the appearance of the first of
the works of Professor A g a r d h , above mentioned, H a n s
C h r i s t i a n L y n g b y e , a Danish clergyman, drew up a system
of his own, artificial in its very nature, and, as a general
one, founded upon too local and scanty materials. His work
is in quarto, entitled Tentamen Hydrophytologioe Danicoe, and
was published a t Copenhagen in 1819, a t the expense of
the Crown. Notwithstanding the imperfections, we have
mentioned, it does him high credit, being full of minute re search
and valuable observation, and accompanied hy a great
number of useful plates. I t likewise contains the most complete
catalogue of algological works and essays hitherto assembled
together. This Catalogue, rendered more perfect,
and brought down to the year 1829, will he inserted in the
present work.
The article on Thalassiophytes, by G a i l l o n , already alluded
to, is little more than a skeleton o f L a m o u r o u x ’s system,
with some alterations; while the Essay by D o r y d e S t V i n c
e n t , in D u p e r r e y ’s Voyage, is, with the exception of some
introductory matter, confined to the description of the species
hrouglit home hy the naturalists of the expedition.
Having thus enumerated the principal systematic writers,
let us retrace our steps, and, in an equally b rief manner, pay
a ju s t tribute to those who, hy tlioir industry and correct observations,
as well as by faithfid descriptions and representations,
have furnished most of the materials of which methodical
writers have availed themselves. F irs t in the list, in
point of time, stand G m e l in and E s p e r , the first of whom
published an Historia Fucorum, the last leones Fucarum.
The Flora Danica, also, which commenced in 1766, at present
conducted by my friend Professor H o r n e m a n n , contains
characteristic figures of numerous Alga. The “ English
Botany,” conducted by Sir J am e s E d w a r d S m i t h and Mr
SowERBY, exhibits in its unrivalled volumes nearly a complete
series of the British Alga.* Last, hut not least, among
illustrated algological works, is the splendid Historia Fucorum
of Mr D a w s o n T u r n e r , extending to four volumes in
quarto. To the ample descriptions and numerous observations
in the work of this excellent botanist, and the beautiful
figures contrihuted to it by the pencil of Professor H o o k e r ,
the modern classification is indebted for much of its accuracy.
We must not, however, content ourselves with a catalogue
raisonnee of those only who have been so favourably situated
as to he able to give their experience to the world in a distinc
t form—or even to those who availed themselves of the
Transactions of learned societies, or the periodical journals of
the day, to communicate their discoveries. In our own
country, L i g h t f o o t , and particularly H u d s o n , contrihuted
many species to the Marine Flora of the British Islands.
D r G o o d e n o u g h and Mr W o o d w a r d , hy their papers in the
Linnean Transactions, and Mr D a w s o n T u r n e r , hy the same
channel, as well as hy his Synopsis of the British Fuci, did
much to clear away many difficulties, besides adding va-
