THE PAST AND PRESENT STATE 
has proved that there is no substance in meteorites not found in 
the earth, except in one or two particular cases. Nickel, long 
supposed to be a meteoric metal, is now found in mineral 
masses of terrestrial origin ; and there are frequently traces of 
positive volcanic matter in stones that have fallen at a time when 
no volcano has been in the immediate vicinity. We know, also, 
that volcanic ejections have been carried even from Vesuvius 
and Etna as far as Constantinople; and that there must be 
thousands of earthquakes and volcanic eruptions of which we can 
know neither the character nor existence. 
ON THE INFLUENZA OF 1836. 
By Mr. S. W. Jeffery, Bland ford. 
Having read with considerable interest Mr. Sewell’s Essay 
on the Influenza, and also the remarks of different veterinary 
surgeons, I feel it my duty to contribute my mite towards the 
elucidation of the treatment of the present epizootic ; especially 
as I have had more than 100 horses under my care within the 
last three months labouring under this disease, and of which I 
have lost only three, and these between fourteen and twenty 
years of age. 
The treatment which I have adopted has been, to abstract 
about three or four quarts of blood, and then to give sp. nit. seth. 
^i, and liq. ammon. acet. Jv twice in the day, until the fever 
is subdued. I then have recourse to vegetable tonics, as ginger 
and gentian, the diet of the patient consisting of bran-mashes, 
gruel, &c. 
I deem cathartic medicines absolutely poisonous, for many 
horses purge far too much in this disease, without any medicine 
at all, and are excessively weak. The post-mortem appearances 
in the two horses that died were, the mucous membrane of the 
trachea, bronchi, and lungs, highly inflamed ; but all the other 
viscera healthy.
