NATURAL CURIOSITIES AND WORKS OF ART. 
461 
j were given ; and living infusoiise were seen 
ji contending with and destroying each other, 
I which excited considerable amusement. The 
j animalcules were the most lively animated 
j objects displayed in myriads in our common 
drinking water : a little brandy was introdu- 
ced, and they all fell to the bottom, showing 
the eifect of ardent spirits in suspending 
! animation. Among the numerous exhibi- 
tions of natural curiosities, we noticed some 
jerolites which have fallen in India ; the one 
at Moradabad in 1806, one at Allahabad in 
1822, one at Ghazeepore in 1827, and another 
at Hydrabad in 1831. There were some 
beautiful specimens of Japhogas Succatus 
and Pteropus Marginatus of Bengal, and fossil 
hippopotamus and fossil crocodile from the 
Sub Himalya, furnished by Col Colvin. Salt 
from the Samber lake in various states of 
manufacture, from Lt. Conolly. The skeleton 
of an ouran outang and one of an albatross. 
Among the works of art we observed three 
casts ; viz. those of King William, — Cobbett, 
and O’Connel in character. Our gracious 
king was considered an admirable likeness. 
O’Connel, in the attitude of animateddebate, 
with one hand grasping his waistcoat, laid 
bare his brawny bosom, with the other arm 
extended and clenched fist denouncing ven- 
geance on the enemies of his injured coun- 
try. Cobbett hoary-headed, reclining in 
despair on a garden bench, was a fine 
picture of intelligence and age. A silver 
cup given by Dwarkanath was an admii'a- 
ble specimen of workmanship by Hamilton 
& Co. The Auckland cup was still more 
creditable to the abilities of Pittar. The 
latter had no blemishes as regarded chaste- 
ness and design, which unfortunately was not 
altogether the case with regard to the for- 
mer. There was also a splendid collection 
of bronze medals, struck inFrance under the 
the orders of Napoleon, in commemoration 
of his victories, and a very perfect Sciogra- 
thicon. 
DR. O’SHAUGHNESSY’S & MARSH’S 
EXPERIMENTS. 
We perceive that the editors of the Quar- 
terly Journal of the Medical and Physical So- 
ciety have given ' ‘ an account ofa new method 
of separating small quantities of arsenic from 
substances, with which it may have been 
mixed, by J. Marsh, Esa.” When we com- 
mented upon Dr. O’Shaughnessy’s descrip- 
tion of this mode of separating arsenic from 
other substances, we had not seen Marsh’s 
clever paper, and therefore Dr. O’Shaugh- 
nessy’s statement (for we conceive the edi- 
torial to be his), that our review was of that 
document, is incorrect. Our description of 
numerous tests and advice to judge and 
juries in quoting the difference of opinion 
among chemical physicians, the professor 
denounces as odd mistakes and a proof of 
our not being, as he is, familiar with the sub- 
ject ; he appeals to men of science in Europe 
to support his assumption. Now we must 
protest against any such appeal, if he had a 
reason on the spot to prove our conclusions 
erroneous : to have given it would have been 
but complying with the claims of legitimate 
discussion. Has the professor so soon for- 
gotten the opinion we gave on his experi- 
ments on the blood ? When we then point- 
ed out his errors, his reply was the same as it 
is now ; viz. that he did not consider himself 
called upon to enter into a chemical dis- 
cussion with us, as our review had denoted 
a total want of practical knowledge of the 
subject. Instead, therefore, of entering into a 
controversy with us regarding the existence 
of a supposed new substance in the blood, 
he would appeal to home authorities. The 
appeal in this case was inourfavor, as shown 
in our number for January 1836, wherein the 
experiments by Brett and Bird, of Guy’s 
hospital, are described, the result of v/hich 
led to conclusions the same as our own. 
We have since received a long com- 
munication from those gentlemen on the 
same subject, which we have not published, 
nor should we have adverted to it now, 
had not the remarks of our friend O’Shaugh- 
nessy elicited this, defence, and compelled 
us to point out to our professional brother 
our desire for free and open discussion of 
important questions. It is by collision of 
opinions that truth is elicited ; but the sub-
