MISCELLANEA.

exertion in hot weather — the encircling bow of the yoke being 
often too tight around the neck and preventing the return of blood 
from the head — the pressure of the yoke on the windpipe pre- 
venting the free ingress of air into the lungs — its pressure on the 
throat producing hoove or blown — the cumbrous yoke with its 
unyielding bow getting more and more into disuse, and the collar 
harness, now so generally introduced, and admirable for its ease 
and comfort to the oxen ; — these are all links in a good cause— that 
of humanity. There is no absurd nonsense here, but the duty of 
man towards the inferior animals is well and worthily pointed out. 
MISCELLANEA. 
The Poison of Lead in Kennels. 
The Queen's Stag-Hounds ~ It was stated in The Times , a 
week or ten days ago, that (in consequence of a discovery which 
had been recently made by a medical gentleman at Windsor, in 
the case of one of the whippers-in to the Royal hunt, who was 
labouring under the effects of paralysis) the cause of kennel- 
lameness has been found to proceed from the presence of lead 
in the water that is supplied to the kennel at Ascot by means 
of pipes composed of that metal, through which the water is con- 
veyed for a considerable distance. Since the discovery of the pre- 
sumed cause of lameness in the Royal pack, the water has been 
analysed by Dr. Ryan, professor of chemistry at the Polytechnic 
Chemical School, and also by Mr. Philips, the celebrated che- 
mist, by order of the Commissioners of Woods and Forests. The 
results of Dr. Ryan’s two experiments are as follow : — The first 
examination was made from a sample of water taken from the 
source or spring-head before it had entered the leaden pipes, 
when the specific gravity of 60 degrees was found to be 1.000.18. 
The imperial pint, on evaporation to dryness, yielded 2.37 grains 
of solid matter. 
The solid contents of an imperial pint were found by Dr. Ryan 
to be
