SANGUINEOUS A PO P L E X Y .

of which has been accurately pointed out by Daubanton, is known 
under the improper name of the angular vein ; it passes at about 
an inch below this one, and at two fingers’ breadth from the 
commissure of the lips in front of a tolerably projecting bony 
tubercle, which may easily be felt near the root of the fourth molar 
tooth by feeling the jaw with the fore finger. 
I have been able, by compressing this vein on the external sur- 
face of the inferior jaw, to obtain more than a pound of blood. It 
is almost always necessary to put a pin in in order to stop the blood. 
In less pressing cases one may bleed from the saphena or brachial 
vein, &c. ; but the jugular and the sub-cutaneous facial veins are 
to be preferred to all others. 
The quantity of blood to be taken from large animals as a means 
of cure is from 500 to 600 grains, or half a pint and more — and as 
a preservative, from 250 to 500 grains, or from a quarter to half a 
pint — for white lambs, from 150 to 200 grains, or about a quarter 
of a pint, varying according to the age, condition, and strength of 
the animals and their plethoric state : the bleeding may be repeated 
should it be deemed necessary. 
All other circumstances being the same, lambs, young rams, 
sheep of two or three years old, which are generally well fed ; 
ewes that have not borne lambs, or that have miscarried, should be 
bled more copiously than ewes that are suckling, those which have 
slunk but a short time before, and sheep that are being fattened. 
By bleeding ewes that are very large, miscarriage is often 
averted, which, as I have before said, often takes place when the 
sanguineous congestion has declared itself in a flock. 
Having thus demonstrated the good effects of bleeding as a pre- 
servative and curative means in sanguineous congestion in sheep, 
we must say, with M. Delafond, that this is not the only treatment 
which must be had recourse to, that a strict dietetic regimen should 
be instituted to second these abstractions of blood. 
When disease of the blood has declared itself in a flock, and 
several beasts die off every day, the animals, after having been 
bled, ought to be rigorously dieted for at least three or four days, 
kept on half allowance for a fortnight, and then only gradually 
allowed to return to their full feed. 
Should it occur during the winter, for the first few days they 
ought to have nothing but well- thrashed straw, refreshing roots, and 
some cooked grain, as barley or rye, and barley mixed ; for drink, 
water whitened with barley-meal, or pure water acidulated with 
vinegar or sulphuric acid, or in which Glauber’s salts have been 
dissolved in the proportions of 500 grains to 100 pints of water. 
These drinks quench the ardent thirst of the animals, render the
