& 4 Blooming Flower,” a favourite Song, sung 
with uaiversal Applause by Mr. Incledon. 
Composed by Ff. Mazzinghi, Esg. 1s. 6d. 
This is a beautiful air; perfectly ap- 
propriate to the subject of the poetry, and 
yemarkably elegant in the turn of its pas- 
sages. The effect of the whole cannot 
fail to attract the most favourable no- 
tice, and to secure an extensive circus 
Tation. 
&¢ Offspring fair of Love divine,” a Canzonet, 
sung by Mr. Bourk at the Bath Concerts. 
Composed by Fobn Whitaker. As. 6d. 
| This is a pleasing little song. The me- 
Yody is smooth and easy, and the expres- 
Literary and Philosophical Intelligence.

sion jast and natural. Something more, 
perhaps, might have been made of the 
accompaniment, which simply consists - 
of a repetition of the notes of the me- 
lody. 
*¢ Woen Hopes endear the Lover's Chain,” a 
Canzonet, with an Accompaniment for the Pi- 
ano-forte. Composed and inscribed to Samuel 
Wesley, Esq. by Foseph Major. 1s. 
This little effort of Mr. Major’s talents 
is of a respectable description; and, both 
for its melody and accompaniment, will 
not fail to be approved by the generality 
of hearers.

a 
YE great national Work of the Agri- 
cultural Surveys of the kingdom-is 
proceeding under the direction of the 
Board of Agriculture, withall the dispatch 
that is consonant with accuracy. Mr. 
Vancouver’s Survey of Devonshire has 
recently appeared, and the same able 
observer is now engaged in the Survey of 
Hampshire. Dr. Ropertson’s Survey of 
Jnvernesshire, the Rev. AntHuR Younc’s 
Survey of Sussex, and Mr. Hotuann’s 
Survey of Cheshire, are just finished 
at press, and willappear in January, com- 
pleting twenty-five counties, and con- 
taining a body of agricultural, commer- 
cial, economical: and statistical informa- 
tion relative to the United Kingdom which 
is no where else to be met with. 
Mr. Pricr, of Appizepors, has juft 
completed an original work on Sheep- 
Feeding,as practised in Romney Marshes, 
in which he is himself a well known and 
much respected proprietor and experi- 
mentalist. The work has been read in 
manuscript by the president and secretary 
of the Board of Agriculture, and is recom- 
mended by them as a inaster-piece on 
this important branch of Agriculture. 
Professor Davy has lately given to the 
Royal Society, in reading the Bakerian 
Lecture, an account of his important dis- 
coveries relating to the decomposition 
or analysis of the Fixed Alkalis. Ex- 
eepting Galvanism, nothing of greater 
consequence in chemical science has 
taken place since the discoveries of 
Priestley and Cavendish, Myr. Davy 
in the Bakerian Lecture of last year, 
on the Agencies of Electricity, sug- 
gested the probability, that other bedies, 
not then enumerated, might be decompo< 
posed by means of that fluid. Since then 
by several powerful Galvanic troughs, 
consisting of one hundred pairs of plates 
of six inches square, ahd one hundred 
and fifty pairs of four inches square, he 
has succeeded in decomposing potash 
and soda. ‘This was effected by placing 
moistened potash or soda on a plate 
of platina, and exposing it to the 
Galvanic circle. Oxygen was disen- 
gaged, and these alkalis were reduced ‘to 
their primitive base, a peculiar and high- 
ly inflafimable matter, which assumes the 
form and appearance of small globules of 
mercury. The globulesare lighter than any 
other fluid as they swimin distilled naphtha. 
The base of potash is of a specific gra- 
vity as six to ten of water. - At the freez- 
ing point these globules are hard and brit~ 
tle, and when broken and examined with 
a microscope they present a number of 
facettes with the appearance of crystalli- 
zation: at 40° of Fahrenheit they are soft, 
and can. scarcely be distinguished from 
globules of quicksilver; at 60° they are 
fluid and at 100° volatile. When expos- 
ed to the atmosphere, they rapidly imbibe 
oxygen, and re-assume their alkaline cha- 
racter. In distilled naptha they may be 
kept four‘or five days; but if exposed ei 
ther to the atmosphere, or to oxygen gas, 
they almost instantly become incrustated 
with a coat of regenerated alkali: this 
incrastation can be remeved, and the re- 
duced globule will remain in naphtha, or 
separated from all contact with oxygen as 
before; the naphtha forming a thin film 
round the globule, and excluding the con- 
tact of oxygen. In some experiments on 
these
