within a few days of the time she was destroyed, will render the 
publication of the case interesting. 
It is comparatively of recent date, or within only a little over 
twenty years, that this form of disease has been well observed 
amongst domestic animals, although the Veterinarian of 1839 con¬ 
tains a case recorded by Gulliver, which though not under that 
jfj name, gives undoubtedly the evidence of its nature, viz.: an in¬ 
crease of the number of the white corpuscles. This condition of 
leucocytosis, it is true, is only a symptom, though varying in its 
character, well marked in some cases, where the disproportion is 
enormously great, while in others it is very much less remarkable. 
The usual normal relative average may be stated as 800, 900, 1,000 
or 1,100 red to a single white corpuscle; of course not universally 
so. In the case recorded, the corpuscles numbered relatively, 
about one white to two hundred and sixty-five of the red blood 
cells. The difference has been sometimes noticed to be greatly 
in excess of this, cases being recorded where the figures stood one 
white to 85, 50, 46, 20, 15 and 12 of the red. The difference in 
man has been observed to be much greater, even standing 1, 2 
3 and 4 of the red to a single white. In all cases recorded, the 
diseased process existed, not only in the external, but also in the 
internal lymphatics, this case presenting this peculiarity, that 
none of the internal organs were diseased. All parenchymatous 
structures, such as the spleen, the kidneys, the intestinal, the 
heart and the lungs were in a healthy condition. The trouble 
was altogether limited to the external lymphatics of the whole 
body, and to a great extent represent a true case of general cuta¬ 
neous leukoemia , or ganglionar leucocijtliemia. The literature on 
the subject of this affection as affecting domestic animals is com- 
Hparatively limited, and amongst the cases recorded by Nocard, 
Griolet, Mauriz, Leblanc, in France, and Leisering, Bruckmuller, 
Siedamgrotzky and Bollinger, in Germany, none of this variety 
of case is found. So far as experience extends, this is the second 
case brought to our notice; another patient somewhat similarly, 
but not so extensively affected, was brought before the clinics of 
the American Veterinary College some eighteen months ago, but 
the case was lost sight of before a correct diagnosis, by counting 
the blood elements, could be accomplished.
