rable pyramid, which resembles polished brass ; and it under- 
goes several changes, till it has attained its full dimensions. In 
rainy weather this pyramid is constantly covered with pearly 
drops of water ; in case of thunder or hail, it will change to the 
finest red, and throw out, rays: in case of wind or fog, it will 
appear dull and spotted; and previously to snow it will look 
quite muddy. If placed in a moderate temperature, it will re- 
quire no other trouble than to pour out a common tumbler full of 
water, and to put in the same quantity of fresh. For the first 
few days it must not be shaken.

PROGRESS OF VACCINATION IN THE EAST. 
Extract of a Letter from Bagdad, dated the 24th of August. 
*¢ Jean de Murat of Constantinople, and at present a merchant 
in Bagdad, has had the good fortune to introduce vaccination on 
the banks of the Tigris and Euphrates, Animated by a desire to 
be useful to his fellow-creatures in a country where small-pox, 
if it be not always mortal, leaves frightful mutilations and defor-

surgeon, having obtained vaccine matter from Dr. Carro and 
Lord Elgin, vaccinated two poor children, whom he procured 
more by means of money than in consequence of any assurances 
of success. The vaccine took in the arms of both. Mr. Jones, how- 
ever, not having been careful in the choice of these two infants, 
one which was in good health recovered well, but the other, 
which had been long sickly, died a few days after being vacci- 
nated. This accident frightened every body ; and Mr. Jones has 
never since been able to procure any other subject for his experi- 
ments. The idea of vaccination was therefore abandoned. 
“ In the mean time, Jean de Murat sent repeatedly to Constan- 
tinople for matter, but all his efforts to introduce it for several 
years were in vain. In 1810, however, having a child born to 
him, he obtained an opportunity of exhibiting in his own family 
the excellence of this preventive of small-pex. He procured vac-
