Torn from his native fieids—ah! foul dis-

Thro’ various toils at length to Britain came, 
Espous’d, so Heav’n ordain’d, an English dame, 
And follow’d Christ ; their hope two infants

But one a hapless orphan slumbers here. 
To bury her the viliage-children came, 
And dropp’ d choice flowers, and lisp’d her

And some that lov’d her most, as if unbless’d, 
Bedew’d with tears the white wreath on

ROYAL SOCIETY or LONDON. 
W ESSRS. Allen and Pepys have laid 
before this learned body an account 
of a great number of experinents, made 
with aview of ascert aining the changes 
produced in atmospheric air and oxy- 
gen gas by respiration; from which, they 
infer : 
1. That the quantity of carbonic acid 
gas emitted is exactly equal, bulk for 
bulk, to the oxygen consumed ; 
therefore there is no reason to conjec- 
ture, that any water is formed by a union 
ef oxygen and hydrogen in the lungs. 
Be Atmospheric air once entering the 
Jungs returns charged with from 8 to 83 
per “cent. carbonic acid gas, ani when 
the contacts are repeated almost as fre- 
quently as possible only 10 per cent. is 
emitted. 
8. [t appears, that a middle-sized man, 
aged thirty-eight years, and whose pulse 
is seventy on an average, gives off 302 
cubical inches of carbonic acid gas from 
his lungs in eleven minutes; and sup- 
posing the production uniform for twen- 
ty-four hours, the total quantity in that 
period would be 39,534 cubical inches, 
weighing 18,683 grains, the carbon in 
which is 5,363 grains, or rather. more 
than 11.02, troy: the uxygen consumed 
in the same same time will be equal. in 
volume to the carbonic acid gas. The 
quantity of carbonic acid gas, emitted in 
a given time, must depend much on the 
circumstances. under which respiration 
is performed. 
4. When respiration is attended with 
distressing circumstances, there is reason 
to. conclude, that a portion of oxygen is 
absorbed: and as the oxygen decreases 
in quantity, perception gradually ceases, 
and we may suppose, that life would 
and . 
man were very 
be completely extinguished on the total 
abstraction of oxygen. 
5. A- larger proportion of carbonic 
acid gas is formed by the human subject 
from oxygen, than from atmospherie 
air. 
6. An easy, natural inspiration is fram 
16 to 17 cubical inches, though this 
will differ in different subjects ; and it is 
supposed, that the quantity of carbonie . 
acid gas, given off in a perfectly natu-_ 
ral respiration, ought to be reckoned at 
less than at atime when pide hs are | 
making on the human subject for the 
purpose, because in short inspirations the 
quantity of air, which has reached ne 
farther than the fauces, trachea, &c. 
bears a much larger proportion to the 
whole mass required, than when the in- 
spirations are deep. 
7. No hydrogen, nor any other gas, 
appears to evolved during the process of 
respiration. 
8. The general average of the defici- 
ency in the total amount of common air 
inspired, appears to be very small, 
amounting only to 6 parts in 1000, 
9. The experiments upon oxygen gas 
prove, that the quantity of air remain- 
ing in the Jungs, and its appendages is 
very considerable ; and that without a 
reference to this cireumstance, all expe- 
riments upon small quantities of gas are 
liable to inaccuracy. 
Mr. Brande has laid before the Royal 
Society, an account of the differences 
in the structure of ealculi, which ~arise 
from their being formed in different 
parts of the urinary passages ; and *on 
the effects that ‘are produced upon them 
by the internal use of solvent medicines.
