40 Agricultuvens Medicine... Law... Mathembtics and Aftronomy, [ July, 
inportant addition to our ficck of phy- 
fical knowledge. Some very ingenious, 
thougn perhaps not altogether decifive, 
fpeculations on the caufe of /imgle vifion, 
will be read in Mr. Crisp’s * Obferva- 
tions on the Nature and Theory of Vi-. 
fion :’’ the writer coincides with Berke- 
ley, and cppofes. Reid. Mr. Lyons, 
ele€trician, has endeavoured to confirm 
his own theory of eleétricity, by “ An- 
Account of feveral- Phenomena, in a 
"Phunder-fiorm near Dover.’” The tranf= 
Jation of ‘‘ BECKMANN’s Hiftory of In- 
ventions and Diflcoveries,’ though not 
accompanied, as it ought to have been, 
withan account of the prefent ftate ef 
the arts, will be acceptable to many read- 
ers. Much as gold and filver-are want- 
ed; the attempt of Mr. Pew, in his 
<< Obfervations onthe Art of Making 
Gold and Silver,’ to revive the exploded 
fiudy of Alchemy, is not likely, in the 
prefent age, to attract much atiention. 
The chemical ftudent is prefented by Dr. 
Waite with atolerable view of the new 
theory and nomenclature of chemittry, in 
«A Summary of the Pneumatico-Che- 
mical Theory.”’ 
AGRICULTURE. 
Agricultura! knowledge may gradually 
receive important improvement, by ac- 
curate furveys cof the prefent ftate of 
_hufbandry in different parts of the king- 
dom. Such furveys‘are, at prefent, at- 
tempted by Mr. Boys, in his ‘‘ General 
View of the Agriculture of the County of 
Kent,” and by Mr. KEnT, in his {* Ge- 
neral View of the Agriculture of Nor- 
folk.” Ufeful information, concerning 
the various methods of agriculture, may 
be had from “ Sir JoHN ANSTRUTHER’S 
Remarks on the Drill-hufbandry,”’ which, 
however, feem rather the retult of read- 
ing than of experience. Practical hints and 
direétions, if not new, yet well arranged, 
will be met with in Dr. ANDERSON’s 
« Effays on Agriculture.’ Some va- 
Tuable fuggeftions, written in a ftyle well 
adapted to excite attention to the fubject, 
occur in Mr. BayLey’s “ Thoughts on 
colle€ting and preferving Subftances for 
Manure.” 
MEDICINE. 
The publications principally deferv- 
ing of notice, under the head of Medi- 
cine, are Dr. WALKER’s “ Treatife on 
Nervous Difeafes,”’ which, though not 
containing much matter altogether. new, 
may be read with benefit by the young 
practitioner; ‘* Medicina Nautica,’ by 
Dr. Trotter, an ufeful performance, 
containing practical obfervations and di- 
plete Syftem of Pleading, 
_ reétions, adapted to general readers, con- 
cerning the difeafes of feamen; Dr 
Cirarke’s * Treatife on the Yellow 
Fever,’ which is faid to be the refult of 
great experience, but abounds in con- 
jeGural theory ; Dr. FAaLCONER’s inge- 
nious and ufeful ‘“ Obfervations refpeét- 
ing the Pulfe ;’’ the Rey. Mr. Town- 
SEND's ‘“ Guide to Health,” containing 
cautions and direétions in the treatment 
of difeafes, which may be ufeful to me- 
dical ftudents ; ahd captain REYNOLDSs’s 
** Aids to Nature,” containing direétions, 
perhaps too minute, for preferving health, 
in childhood, and through life« 
LAW. 
The lawyer will efteem a valuable ad- 
dition to his library, Lord Chief Juftice 
Haves’s treatife, lately publithed, from 
an authentic manufcript, by Mr. Har- 
grave, entitled, “* The Jurifdiétion of 
the Lord’s Houfe; or, Parliament con- 
fidered according to the ancient Records,” 
a treatife of authorities and illuftrations 
on an important fubje&t. The “ Poft- 
humous Works of CHARLES FEARNE, 
Efq.” will be. fufficiently recommended 
to the profeffor, by the name of the 
author. Mr. WenrworTu’s “ Com- 
” contains an 
ufeful colle@tion of entries, under every 
head. Mr. PLowpeEn’s treatife “ Gn 
the Law of Ufury and Annuities,”’ dif- 
cuffes the fubjeét with great ability, both 
hiftorically and legally. A comprehenfive 
and well-methodized work, entitled, 
«<A praétical Arrangement of the Law 
of Excife’’ has been publifhed by Mr. 
Hicumore. If an abridgement. of 
Blackftone’s commentaries can be necef- 
fary, the ftudent is furnifhed with a 
good one, by Mr. Curry. The late 
unpopular attempts to reftrain the free- 
{ 
dom of fpeech and writing, are folidly 
and temperately examined, in ** Confi- 
derations on Lord Grenvijle’s and Mr. 
Pitt’s Bills, concerning Treafonable and 
Seditious Praétices and Unlawful Affem- 
bee ese ee 
MATHEMATICS AND ASTRONOMY. 
Mathematical learning, which, except 
in its great feminary at Cambridge, is 
too much negleéted, has a_ valuable 
friend and patron in Baron MASERES, 
who has prefented the world with 
“* Scriptores Logarithmic: ;’’ a colleétion 
of curious traéts, on the nature and con= 
firu€tion of logarithms; on the binomial 
theorem, and other fubjeéts conneéted 
with the doctrine of logarithms. The 
practical aftronomer.may, perhaps, learn 
to correét fome of his computations, by
