SYNOPSIS OF VETERINARY CONTINENTAL JOURNALS. 83 
found to be attributable to the development of a swelling on 
one of the limbs. This usually occupies the upper part of 
the limb, but in some cases it appears on the trunk, as in 
the jugular channel, the intermaxillary space, or the lumbar 
region. Wherever it occurs the tumour is irregular in form 
and without defined limits, and spreads with striking rapidity. 
In eight or ten hours it has attained a great size. At first 
homogeneous and extremely painful all over, it gradually 
loses its sensibility from the centre, and becomes crepitant 
and sonorous, like a bladder filled with air. All its parts are 
black and pulpy. When incisions are made they give exit 
in the early stages to bright coloured blood, later to a liquid 
resembling venous blood, and later still to a frothy serosity. 
Meanwhile the fever increases, the pulse is hard (90 to 110 
per minute), the respiration becomes painful and accelerated, 
the temperature of the skin very much elevated. The 
patient becomes feeble, listless, and staggers in his gait. 
The loss of power increases until the animal falls, where he 
remains stretched on the ground. The skin becomes cold, 
convulsions set in, and the case terminates in death, gene¬ 
rally from thirty-six to forty-eight hours after the first 
appearance of the symptoms. If the jugular be opened 
during the course of the attack it will be found that the 
blood is thick and black, and coagulates rapidly, and does 
not separate its serum from its clot sooner than healthy 
blood. Of course our readers will recognise this description 
of (c black quarter/’ The question under discussion, there¬ 
fore, is of great interest to us, for Dr. Greenfield, in his recent 
lectures, has reminded us that we are by no means thoroughly 
acquainted with the pathology of this affection and its rela¬ 
tions to splenic apoplexy. Attempts were made to repro- 
duce this disease by means of inoculation. The recent 
investigations on splenic fever had suggested the proper 
course to follow in the research—1. To examine minutely, 
under the microscope, blood from the heart and large blood¬ 
vessels, also the pulps and liquids obtained from local lesions 
and lymphatic glands. 2 . To cultivate the diseased pro¬ 
ducts, either in the organism by inoculations varying in 
methods of different healthy animals, or in a moist chamber, 
or in Pasteur’s tubes, with aqueous humour or urine as a 
medium. i( Our experiments may be grouped in five series, 
according to the source of the inoculation material used- 
(1) From a charbon tumour before death, (2) or after death. 
(3) From a diseased lymphatic gland after death. (4) From 
the circulating blood. (5) From the blood-circulating 
system after death. Whatever the source of the matters
