OPERATIONS WITH ANTISEPTIC PRECAUTIONS. 101 
the horse can get up. Then, with the horse standing, the 
field of operation is again rinsed out with sublimate water and 
the tail tied up. The latter is important to prevent the tail from 
dirtying the wound. 
The disinfection of the instruments (knives, scissors, and 
needles) necessary for the operation is effected by simply dip- 
ping them in sublimate water every time vefore they are used. 
The after treatment consists in merely letting the patient 
stand for six days, tied high, so as to prevent his dirtying or 
dragging the wound on the litter, and rinsing out the field of 
operation daily once or twice with sublimate water. A bandage 
or stispensory is not put on, as an occlusive bandage on the 
horse in this region is impossible. Besides, a dry scurf forms 
on the wound shortly, which keeps the wound closed. 
In the course of the next two days oedema sets in in the 
vicinity of the penis, which disturbs the circulation some, but 
is of no importance. This disappears quickly when the pa- 
tient can take exercise again, which is about six days after 
the operation. 
Occasionally fever sets in on the second day after the opera- 
tion, which rises even to 39.80 c; however, this is a simple re- 
sorption fever, which mainly differs from the consecutive sep- 
tic wound fever, for the patients are lively and eat their food 
heartily, while the latter form of fever is always associated 
with the general symptoms of loss of appetite, depression, dis- 
inclination to walk, etc., etc. 
We may also mention as a complication, which, however, 
seldom delays healing, those hemorrhages which set in after 
the horse arises from the operation. BAYER mentions 
this accumulation of blood into the scrotal cavity, and thinks 
it to be the blood which flowed into this cavity during the 
operation, but according to my observation this haemorrhage 
originates from the veins that are cut through when the scro- 
tum is opened, and which are located between the common 
tunica and the dartos. During the operation, on account, of 
the dorsal position of the patient, there is no recurrent mo- 
tion in these veins, which, however, comes into effect imme-
