~ We noticed the Prodromus to this work 
in vol. 14. p. 583, and were jultified in 
anticipating that the prefent would form 
a valuable addition to our works on Na- 
tural Hiftory. Mr. H. fays, ** that many 
years have elapfed, fince, with enthufiaftic 
pleafure, he began to collect, arrange, 
and defcribe the natural produétions of 
this our fertile and happy ifland; but 
more efpecially its birds, infegts, and ve- 
getables. For thefe purpofes he has dili- 
gently examined many parts of England 
perfonally, and ufually on foot and alone; 
but fometimes accompanied with pecef- 
trian friends of congenial fentiments and 
tafte. Induftrioufly has he fought, and 
never once in vain, a great variety of 
woods and lawns, hills and vales, marfhes 
and fens ; one fummer only, travelling in 
various journeys, not fewer than a thou- 
fand miles, in {pite of heat and cold, wet 
ahd drought, ani various o:her concomi- 
tant impediments. 
The work altogether difplays) much 
accurate and difcriminative obfervation. 
Annexed to the Lepidoptera are ‘* Mi/- 
cellanea Naturalia, five Differtationes va- 
ri@, ad Hiftoriam Naturalem fpeciantes.” 
The fir and moft confiderable of thefe 
differtations is a new arrangement of the 
genus Mefembryanthemum, and defcrip- 
tions of fuch fpecies as were not defcribed 
before, with their place of growth, \dura- 
tion, and time of flowering. Many years 
fince, Mr. H. publithed fome obfervations 
on this genus of plants; he has fince greatly 
increafed his collection of fpecies; and 
has had the fatisfation of feeing many of 
them, now he believes for the firft time, 
perfect their flowers in Europe. Mr. H. 
enumerates no fewer than 211 fpecies ; 
more than 160 of which he himfelf pof- 
fefles ina living flate, All the known 
fpecies are now therefore publifhed; and 
Me. Haworth has de(lcribed diftin€&ly the 
parts of fructification of fuch as are new, 
with {pecific charaéterg of thofe which he 
had delcribed before, The fecond differ- 
tation is on the genus Tetragonia; nine 
Retrofpeel of Domeftic Literature.—Natural Hifory: 
fpecies are-enumerated, feven of whieft 
are technically de{cribed from living plants, 
in the poffeffion of the author. The third 
differtation is on the genus Portulaca, or, 
as Mr. H. fpells it, Portulacca: he is of 
opinion, that the divifion of this. genus © 
irito two, is not authorized by any diftinc - 
tion fufficiently conftant and appropriate : 
it may, hereafter, he thinks, be divided. 
into four, but at prefent he prefers keep-— 
ing it entire. The fourth differtation is 
a new arrangement of the genus Saxifraga, 
as far as it is cultivated in Britifli gar- 
dens. It extends to 49 f{peciés; they are 
arranged under the following feéticns: 
nudiculates: irregulares; ligulate; cilt- 
ata; lobata;and fiolonifere. The fifth dif- 
fertation contains a defcription of twenty- 
four {pecies, which, as far as the author 
knows, have not been before defcribed, 
viz. three fpecies of craffula, one of orni- 
thogalum, four of narciflus, one of coty- 
ledon, three of oxalis, four of euphorbia, © 
one of fempervivum, fix of caétus, and 
one of cacalia.. All of them are now in his 
poffeilion, except the ornithogalum, for a_ 
fight of which, in a living flate, he is in-. 
debted to Mr. Whitley, of Brompton, 
who received roots of it from the Cape 
of Good Hope in 1803. The fixth and 
laft differtation conifts of obfervations on 
feveral technical terms ufed by Lionzus, 
or others, in the fcience of botany, which: 
are either obfcure, and of difficult com- 
prehenfion, or milapplied, or fynonimous 
with others in aftual ue. 
Mr. Haworth gives us reafon to expect, 
in a future publication, differtations on the 
following fubjeéts. 1. Aves Britannica, 
feu Synopfis Avium Britannicarum, with 
remarks. 2, Reptilia Britannica, with 
remarks, 
craflula, of the genus euphorbia, and the 
genus caétus ; with defcriptions chiefly de- 
rived from living fpecimens in his owa 
collection. ;
