pearance when seen in a flask, burning with a brilliant flame, 
and ignitible only with a wick — hence no danger of explo- 
sion ; and two, brown in colour, useful for machinery and 
spindles, and with the advantage that they produce none of 
the corrosive effects on metal produced by other oils, for they 
are not decomposable into an acid. Then there is a detergent 
fluid that removes spots, without staining even the most deli- 
cate coloured silks, to which the name of Sherwoodole is given ; 
and we have seen small specimens of a splendid crimson 
powder got out of the wonderful tar, which, it is thought, will 
be much prized by dyers. And the researches are still going 
on, for the products are not yet all discovered ; hence we have 
a new import, and a new resource for industry. The Burmese 
dig holes in the ground near the Irawaddy, and the tar flows 
slowly in from the surrounding soil, and, as it accumulates, 
is ladled into iron tanks, and hermetically closed, to prevent 
the escape of the volatile matters/ 5 
Who after this will be bold enough to assert that science 
has contributed nothing to the necessaries of life ? Not to take 
into consideration how much it enhances its comforts, and 
adds to its elegancies. And who would have anticipated 
that from such a material, compounds so dissimilar could 
have been obtained ?

FRACTURE OF THE TIBIA. 
By R. H. Dyer, M.R.C.V.S., Waterford. 
The subject of the accident was a bay mare, twenty-five 
years old, the property of a gentleman in this town. Early 
in the month of June a carriage-horse confined in an ad- 
joining loose box to that which was occupied by the mare, 
by some means or other made his way, during the night, 
into the mare’s box. During this nocturnal visit, the mare 
received a kick on the inside of the right hind leg, about two 
inches above the hock-joint, cutting the mtegument only , as ivas 
supposed. The owner not imagining that any serious injury 
had been sustained, merely used the necessary and useful 
application of cold water bandages for nine days. At the end 
of this time, he informed me, that he was more than usually 
careful in examining the wound before retiring for the ni°-ht.
