M. Bisubonwe has difcovered that 
the feeds of goofeberries, wafhed, dried, 
and roafted, are a good fubftitute for 
coffee. When mixed in equal parts of 
real coffee, the tafte does not all differ 
from that of ordinary coffee. 
It has been difcovered, from the Tranf- 
actions of the Academy of Sciences at 
Paris, for the year 1700, that animal 
eie&tricity, or Galvaniim, was known at 
that period. 
CoLLer DEscosTiLs hasannounced a 
new metal found in the black duit left by 
platina, when diffolved in the nitro-mu- 
riatic acid. The principal properties of 
' this mezal are :—it gives a red colour to 
the triple falts of platina ; with the triple 
ammoniacal falt of platina it is precipt- 
tated; it is eafily reduced; it diflolves 
readily in acids, when in the metallic 
ftate; the oxides are green and blue, or 
at leaft communicate thefe colours to the 
acids in which they are diflolved, and 
they feem to be volatile. C. Defcoftils found 
that the fand which accompanies platina 
contains titanium, when fufceptible of at- 
traGiion by the magnet 3; and, that when 
not fo, it contains chrome. Fourcroy and 
Vauquelin have written en the fame fub- 
jet, and admit the difcovery to belong 
to C. Defcottils. 
Preteflor Vattr and Dr. Pezron!

The following is M. Wootr’s method 
of meafuring the contents of any pipe: 
«« Square the diameter in inches, ano the 
product will be the number of pounds of 
water in every yard length of the pipe; 
or, if the Jaft figure be cut off, or confi- 
dered as a decimal, the remaining figures 
“will give ale-galions in the yard.” 
A new Philofophical Journal has been 
4stely eftablifhed at Madrid, the object 
of which is to treat of phyfical and ma-

ture, and the fine arts, 7 
A curious Petrifaétion has been difco- 
veredat Vaucelles, in the north of France. 
A workman, in breaking a ftone that came 
‘from the ruins of the Abbey, divided it into 
two parts, one of which prefented the 
‘impreffion of a fith, and the other the 
fame fith in relzevo. Upon careful exa- 
mination it was found to be a fifh in the 
molt excellent ftate of prefervation, It 
Literary and Philofephicat Intelligence.

appears to be of the abdominal clafs, and 
afalmon. The fcales are cf a violet co- 
lowr mixed with yellow ; the colours of the 
impreffion and of the re/zevo are the fame. 
The ftone was originally taken from a 
yuarry in the neighbourhood of Vaucelles, 
which has been long abandoned. Bat if 
further obfervations were made upon the 
fiones of this quarry, they might exhibit 
the fame phenomena as the mountain near 
Verona. 
The late Mr. HumBotpT defcended 
into the crater of the volcano of J orcello, 
which ftill burns, to the depth of feventy 
toifes; being only about fifteen ‘toifes 
from the borrom. He ftated, in one of 
his letters, that the examination of thts 
volcano would enable him to throw con- 
fiderable light on the nature of thele ter- 
trible phenomena. 
A root of jalap, breught ortgmally

The Aguf Earth, hitherto ftppofed to

The Royal Academy of St. Peterfbure 
have received letters dated the 25th of latt 
Otober, at Santa Cruz, in the ifland of 
Teneriffe, from their correfpondent M. 
VON KRUSENSTERN, the commander of 
the two Ruffian thips,. which have failed 
eon a voyage round the world. Their 
voyage from Fa!meuth to this place was 
extremely expeditious. On the 25th of 
Ogiober, the fhips had already taken on 
board a fupply ef water and svine, and 
weré preparing to fet fail the following day 
for Rio Janeiso, in the Brazils, where they 
are to remain fome wecks. On the voy- 
age, in north Jat. 37° 40%, and 3° 28? 
eaft long. from the firft meridian, the ex- 
pedition had an opportunity of oblferving 
amo remarkable meteor. On the roth 
of OSober, in the evening, they faw in 
the fouth-weft a large fire-ball, which, at 
the height of fifteen degrees, took a di- 
reGtion, completely horizontal, towards 
the north-weft, when it burft. It had a 
very Jong tail, which was fo bright that 
that the whole fhip was for the fpace of a 
minute illuminated by it. The moft re- 
markable cireumftance, however, attend- 
ing it, and which indeed is almoft without 
a parallel, was the uncommon power of 
the luminous matter; as bright ftreaks 
continued vifible in that quarter for up- 
wards of an hour after the fire-ball had —
