1799.) Fifty Articles of Literary and Philfaphical Intelligence. 147 
‘The firft number of ‘* The Medical and 
Plyfical Journal,’ makes its appearance 
on the frit of March, under the immedi- 
ace fuperintendance of Doctors BRADLEY 
and WiLtuicH. Among other valuable 
articles, will appear a diflertation at large 
by Dr. BRADLEY, on the nature and 
practice of Inoculation tor the Cow Pox, 
avith an account of the recent experiments 
- in London, illuftrated by a coloured re- 
prefentation of the puttules, drawn in 
London from the life. 
The learned Dr. JouN GILLIES, whofe 
late analyfis and tranflation of the works 
of Arittotle have revived the tame and ufe- 
fulneis of that philofopher, is engaged in 
compoling a continuation of his hiftory of 
Greece, which will probably poflets all 
the accuracy, philofophy, and eloquence 
avhich are admired in the former part of 
this work, while it will be free from that 
turgidity of ftyle which has been not mn- 
defervedly blamed in the daft writings of 
Dr. Gillies. 
The Rev. Dr. THOMAS SOMERVILLE, 
of Jedburgh, whole recently publifhed 
hiftorical work is read with general eager- 
nefs, is underftcod to have prepared for 
the prefs a volume of fermons of very 
great original merit. 
An annual collection of poems is about 
to be published, on the plan of the French 
and German Almanacks of the mufes. 
Contributions fhould be addrefled to Mr. 
Corrie, Briftol, where the firft volume 
will {peedily go to prefs. 
A metrical Romance has been under- 
taken in that city, called “« The Defiruc- 
tion of Dom Daniel.” 
The celebrated CRELL, of Germany, 
has recently communicated to his philo- 
fophical friends in this country, an ac- 
count of a ieries of ingenious and accu- 
rate experiments, by which he has ac- 
complithed the decompofition of the boracic 
acid. Digeffion, with a long-continued 
heat, was one of the principal means 
which he employed. Az zaflamimable mat- 
ter was found to be one of the principles 
of the acid decompofed. 
Mr. RevevLey, archite& and engineer, 
is engaged upon a work relative to the 
port of London, which is nearly ready 
for publication. It is intended to give a 
more complete idea of the fubject than 
has hitherto appeared, and will conclude 
aith feveral new plins fer tke improve- 
ment of the port of London, and with 
that which was laid before the committee 
of the houfe of commons in April 1796. 
Mr. Perkins, of Leicefter-fquare, has 
in the prefs a tranilation of the work an- 
nounced in our Magazine for November 
lait, entitled ‘* Perkin,” lately pub- 
lifhed in Germany, by Dr. Tope, phy- 
fician to his Danith Majelty. 
A Hiftory of Liverpool, from the ear- 
lielt period to the prefent time ; with an 
account of the river Merfey, from its 
fource to the fea; and a {ketch of the 
principal objects on its banks, is pre- 
paring tor early publication, 
Agriculture.—It, has been commonly 
fuppoted by farmers, that feeds and plants 
will degenerate, unlefs the ground on 
which they are planted be frequently 
changed. Some obfervations and experi . 
ments that have been lately made in this 
country, as well as in America, feem to 
render the truth of this {uppofition doubt- 
ful. It has been found here, that even 
potatoes may be conftantly grown on the 
fame piece of ground without any dege-~ 
neration, provided the cuttings be always 
made from the finelt potatoes, inftead of 
the fimalle#t and worlt, which have a@u- 
ally been employed for this purpofe; and 
in America, it has been fhewn, by the ac- 
tual experiments of Mr. Cooper, that 
the fame thing happens with retpect to 
the feeds of the long watery {quath, early 
peas, potatoes, and feveral other kinds of 
vegetables. The fame principle has, in- 
deed, long ago been applied in the breed- 
ing of animals, by Mr. BAKEWELL. It 
is generally known, that he improved his 
breeds by merety coupling thofe in which 
the properties he wifhed to produce were 
the mot{t evident, not regaiding conian- 
guinity, or any other circumftance. 
This isa matter of fuch extenfive ap- 
plication and importance, that it ought 
more particularly to engage the attention 
and obfervation of the practical farmer as 
well as the horticulturift. 
In the application of manures to lands, 
too little regard feems to have been paid 
both in refpect to its nature, and the time 
of its being laid on. In regard to the 
laft, it has been a common praétice for 
farmers to apply manures to grafs lands 
during the time of froft in the winter. 
This is certainly an improper praétice, 
as during fuch periods, no advantage ean 
be derived to the land from it, and, at the 
thaw, much of its virtues muft be wafhed 
away, and its foluble parts be deftroyed 5 
the ground being, in this ttate, incapable 
of abforbing liquids. Many other rea- 
fons forbid this praétice, which may be 
{een in an ingenious paper written by Dr. 
FENWICK. He conceives, that as the 
claftic fluids are the greatel fupports.of 
vegetation, manures gught to be applied
