late some more able pen in the profession to establish a code of 
laws relative to soundness, by which the repute of the profession 
will be rescued from the stigma under which it is now occasionally 
thrown, as well as the innocent and honourable man go unpunished : 
if so, it will fully satisfy

ON THE EFFECTS OF AETHER. 
By ALEXANDER Henderson, Veterinary Surgeon to the Queen 
Dowager ; and W. A. CHERRY, MM.C.V.S. 
[Continued from page 200.] 
Experiment V. — Friday , March 19. A brown well-bred mare, 
middle aged, fifteen hands high, and not manifesting any disease 
of the vital organs, was submitted to the action of the vapour of 
sulphuric aether. The apparatus now employed was a modification 
of those formerly used, an opening being left of small size to admit 
atmospheric air; six ounces of aether were put into the receptacle : 
the effect was soon evident, but no violence was manifested : she 
stood with her croup in a corner, and pressing backwards with all 
her force, evidently alone supported by the angle formed by the 
walls. After three minutes and a half inhalation, she fell with 
but little plunging, and lay quite still, inhaling the vapour for an 
equal period, after, as before, falling, not shewing sensation on be- 
ing pricked, and no desire to resist on the legs being pulled about. 
She lay dozing for ten minutes, then got up, staggered about, but 
not in any great degree. The pulse before commencing the expe- 
riment was small, quiet, and a little below 40 ; it rose to a ratio 
varying from 60 to 70, according to the apparent action upon the 
system. After the experiment it sank to 43, and remained full, 
but soft, for some time after. 
Experiment YI . — March 23. The same animal was again 
submitted to experiment, but on this occasion with an apparatus 
on an entirely new principle. From a defect in the size of the re- 
ceptacle, a sufficient quantity of aether could not be introduced, 
and some time was expended in producing an effect sufficient to 
cause prostration- About twelve ounces of aether were consumed, 
and, had it not been for the fault before noticed, probably six ounces, 
or even less, would have been sufficient to cause the mare to fall ;
