the genus minum, by Dr. Smith. In 
Art. 8. Mr. Dawfon Turner has deferib- 
ed, with his ufual clegance and precifion, 
four new Britifh lichens, with coloured 
igures. The fame gentleman has writ- 
ten, in Art. ro, fome remarks upon the 
Dillenian Herbarium. Art. 19 contains 
Biographical Memoirs, by the Prefident, 
of feveral Norwich botanifts. At the 
head of this lift will be added, by fome fu- 
ture biographer, the name of Dr. Smith 
himfelf, who refides in the place which 
had the honour of giving him birth. 
It is fufficient to announce the appear- 
ance of a fecond volume, tranflated from 
the German, of KLarrorn’s * Analyti- 
cal Efjays.”” 
This chemiff, fo celebrated for the ac- 
curacy of his analyfis, has here given an 
account of numerous fubftances which 
have undergone his. rigid examination,— 
‘There are very few individuals to whom 
the fciences of chemiftry and mineralogy 
are under greater obligations than to M. 
Kiaproth. 
** Organic Remains of a former World ;” 
an Examination of the mineralized Re- 
mains of the Vegetables and Animals of 
the antediluvian World, &c. By James 
PARKINSON. 
The firé volume only of this work has 
yet made its appearance, containing an 
examination of the vegetable kingdom: it 
difplays extenfive reading, and contains a 
confiderable body of curious and intereft- 
ing faéts, which will be confulted by the 
geologift, who probably may not coincide 
in the theories which Mr. Parkinfon de- 
duces for them. 
Mr. Howarp has publifhed a very 
fhort, but ingenious pamphlet, ‘* Oz the 
Modification of Clouds, and on the Princi- 
ples of their Produdion, Sufpenfion, and 
Deftrucion.”” 
The fubje& is curious, and the mode 
of confidering it, at lea(t, novel. . Our 
meteorologitts, referring to their barome- 
ters and other fimilar inftrum<nts, record 
the actual fiate of the weather, but have 
feldom much fkill in prognofticating the 
future. The mercury in the barometer is 
affefted by fo many different caufes that 
nothing can be more fallacious than its 
indication. The method purfued by Mr. 
Howard is likely to improve the feience of 
meteorology: he attempts to define the 
leading varieties which the clouds affume, 
and ta eftablifa a nomenclature de(criptive 
of thefe different modifications, by which 
means ob{ervations may .be more eafily 
made, and more accurately recorded.— 
En other branches of natural philofophy, 
he has adopted terms derived from the 
dead languages, founding them, however, 
upon the Latin in preerence to the Greek, 
as the former ‘are more generally intelli- 
gible. 
MATHEMATICS, MECHANICAL PHILOQ« 
SOPHY, AND GENERAL SCIENCE, 
Mr. Freno has published a (econd vou 
lume of his ** Evening Amufements.” 
The plan’ of this work is fo happily 
conceived, and fo admirably executed, 
that it gives us great plea(ure to infer 
from Mr. Frend’s profecution of it that 
he has received that encouragement from 
the public which his labours aré entitled 
to. ‘The prefent volume defcribes the 
Criking appearances in the Heavens for 
the-current year, 1805. 
“* The complete Navigator ;” or an eafy 
and familiar Guide to the Theory and 
Praftice of Navigation; with all the re~ 
quifite Tables: illutirated with Engray- 
ings. By A. Mackay, L.L.D.. &c. 
“A Collefion of mathematical Tables,? 
for the Ule of Students in the Univer&- 
ties, for the pragtical Navigator, Grogra. 
pher, Surveyor, &c. By A. Mackay. 
The great fault of thefe works is, that 
they endeavour ta embrace, in a given 
compals, more knowledge and informa. 
tion than it was poffible to comprefs with- 
in-the afligned limits. The former of the 
two works begias with the principles of 
the {phere, and queftions on longitude and 
latitude; thefe are followed by an ac- 
count of the log, the compafs, the me- 
thod of founding, tides, and Gunter’s 
{cale: the geometrical and trigonometri~ 
cal portions are much too meagre. The 
fecond, third, and fourth. books explain 
the nature of different modes of calculat- 
ing, as by plane, traverfe, parallel, mid- 
dle latitude, Mercator’s oblique, and cur- 
rent failing, The canftruction of charts 
is then given; and various inftruments, 
as the yuadrant, fextanr, &¢. A jour- 
nal of a voyage is given, and inftrac: 
tions how to make one. The fifth book, 
is employed on mifceilaneous fubjeéts, as 
the menfuration of heights and diftances 
of objects; the methods of furveying, 
coafts and harbours, &c. The 
book contains the tables, with their ex~ 
planation. - 
The fic volume is publithed of Profef 
for Ropison’s ‘+ Elements of mechanical, 
Pbhilofophy.”’ ‘ 
The work, if ever completed, which, 
notwithitanding the much-lamented, death, 
of the author, we hope may be the cafe, 
will contain the fubftance of a courfe, of 
leGtures which the learned. profeffor deli- 
vered 
fixth,
