ment, and ascertained that the serum is more abundant in the 
blood of women and persons of a lymphatic temperament; and 
albumen, fi brine, and the red particles comparatively deficient. 
He then enquired whether the blood of persons labouring under 
jaundice contained bile, or some of the materials of that fluid, or 
some of the immediate principles which compose it, as a yellow 
matter; margaritic and oleic acid; a peculiar resinous acid; 
chloresterine; a fatty matter not acid; an exceedingly bitter alka¬ 
line matter; a colourless saccharine principle; and two colouring 
principles, one of a blueish green, and the other a yellow orange. 
These principles, supposing that they exist in the blood of 
jaundiced persons, can only do so in small quantities; can have 
no marked characters; and, consequently, their presence is difficult 
to be ascertained. M. Chevruel had already detected the blue 
and yellow colouring principles in the blood of infants, attacked 
with jaundice: the author of this memoir also ascertained their 
existence, and that of another principle, composed of albumen 
and soda, little or not at all soluble in water. He also adds, 
that the blood of jaundiced persons contains only seventy-seven 
instead of 128 parts of colouring matter out of a thousand.—

Theory and Treatment of Broken Wind. 
By Mr. Knowleson, Fifty-seven Years in full Business. 
People have had various opinions respecting its cause, and 
why some horses are more subject to it than others; but of all 
the opinions hitherto delivered, that of Mr. Gibson seems the best 
founded. He thinks that it is frequently owing to the hasty or 
injudicious feeding of young horses for sale; by which means 
the growth of the lungs, and all the contents of the chest, are 
so much enlarged, that in a few years the cavity of the chest is 
not sufficient to contain them, when they expand themselves to 
perform their proper functions. Nor is this opinion founded upon 
bare conjecture; for horses that have died broken-winded have 
been opened, and the lungs and other parts found too large for 
the chest. But although hasty feeding is often the cause ot this 
disorder, yet it is not always, for a narrow chest may cause it. 
It has been observed, that horses rising eight years are most sub¬ 
ject to it. The reason of this is, because ahorse arrives at his full 
strength and maturity at that age. At six he generally finishes
