hot, nor exposing them, on the other hand, to the vicissitudes 
of the weather. All that I would recommend in addition 
to this, is the administration of common salt in the food. 
Although there is little or no chance of cure, I have had 
several cases which have recovered. I will briefly allude to 
one. Mr. Jenkinson, of Stanton, sent for me to a sturk, 
which presented every symptom of the disease, the part 
affected being the muscular portion of the shoulder, extend- 
ing to the dorsal vertebrae and occupjdng a space of about 
five feet in circumference. I first administered a strong 
stimulant, and next made deep punctures with my lancet all 
over the part affected, so that every square inch of the skin 
had an incision in it. I then applied a saturated solution of 
nitre in hot water, and ordered this to be almost constantly 
used. The animal as said before recovered.” 
SUPPOSED CAUSE OE GLANDERS AND FARCY. 
By Percival Smale, V.S., Leamington. 
In my investigations of morbid structures, which, as far as 
my limited practice has enabled me, I have always availed 
myself of, I think I have discovered a probable cause, in the 
capillaries being atrophied, of tubercles of the lungs of horses 
dying of sub-acute pneumonia or phthisis. I propose, there- 
fore, to state in as few words as I can, my reasons for coming 
to such a conclusion. 
I believe that pneumonia (or at least broncho-pneumonia) 
is frequently caused by a suspension of the secretion from the 
mucous membranes of the bronchi, thus leading, through a 
partial dryness of the inner coat of the air-cells, to the reten- 
tion of carbonic acid in the circulating fluid, and so pro- 
ducing congestion and stagnation, which, if not speedily re- 
lieved, will result in loss of the vitality of the blood contained 
in the extreme branches of the capillaries. It further appears 
to me, that the carbonic acid is thus made to unite with the 
earthy elements of the system forming carbonates, while the 
aqueous fluid is absorbed, and the so-called tubercle produced, 
which may be either miliary, unciform, or pisiform, according 
to the part of the capillary system affected. The gray colour so 
often found in the deposit, I think may be attributed to the 
iron which is present, as is the gray colour of the nerve- 
matter of the ganglia. 
If this theory be correct, we can easily account for the
