TETANUS CURED BY ETHER.

the invariable employment of large wheels, on account of their 
doing less injury to the roads — these engineers pretend to de- 
termine the weight and draft of a vehicle. 
The draft of a carriage depends entirely on the construction 
of its wheels. We are now speaking of a carriage without 
springs ; for when springs are added — an addition so desirable, both 
on account of the preservation of horses as well as roads — the 
traction is diminished b}' one-fifth. In the construction of wheels, 
barring their diameter, the axle-tree, and the friction between it and 
them, are the points to be looked to. 
General Idiopathic Tetanus cured by Ether, admi- 
nistered in the form of Fumigation and Clyster. 
[Clinique of the Alfort School, “ Recueil de Med. Yet.” for Oct. 1847.] 
A RIDING mare, nine years old, the property of M. Harve, at 
Charenton. had for three days been failing in her appetite, listless, 
and lazy at work, for which she was bled by a veterinarian, but 
without benefit, and therefore he brought her to the College to 
have her submitted to proper treatment. 
Her SYMPTOMS at present are — lofty carriage of the head ; ears 
erected and fixed ; nostrils rigid and dilated ; eyes fixed, pro- 
minent, and brilliant ; pupils contracted ; nictitating cartilage 
thrown over the cornea on excitation ; motor muscles of the jaws 
firmly contracted, occasioning insurmountable resistance to the 
separation of the jaws ; muscles of the neck, back, and loins, in 
the same state of tension ; tail slightly erected ; limbs stretched 
out, giving to the trunk the appearance of being supported by 
four pillars, and making progression to resemble that of an auto- 
matic machine, moving all of a piece ; the vertebral column ap- 
pearing as inflexible as a metallic rod ; under the excitement of 
motion the ears and tail growing more rigidly erect ; the muscles, 
in particular the extensors of the limbs, contracting and elongatingin 
a strange remarkable manner, the same phenomenon being apparent 
in the muscles of the thorax and abdomen. In the stable, the 
prehension, mastication, and deglutition of food, solid and liquid, 
are attended with so much impediment, that these functions, after 
all, are but imperfectly performed. The respiration is short, 
catching, and accelerated ; the pulse slow and wiry. 
The Diagnostic, by symptoms so pathognomonic, was ren- 
dered unequivocal. 
PROGNOSTIC, grave. Tetanus being a disease in horses com- 
monly fatal; recovery being the exception.
