REPORTS OF CASES. 
up live days before my visit, to break him to harness, and fed 
him on hay and grain. He ate well and showed no sign 
of a lump on the neck. On October 26th, at night, while the 
colt was near through eating his ration of hay and corn, the 
proprietors noticed the animal to have violent cramps of the 
neck, causing great agony and distress. 
Symptoms .—I found the colt standing away from the man¬ 
ger, saliva dripping from the mouth and nostrils. On the 
lower portion in front and somewhat to the left side of the 
neck, 1 noticed a tumor, firm and solid on pressure, covered by 
the sterno-maxillary and Lyoidien muscles, so that it was very 
difficult to give the real size of the tumor. However the en¬ 
largement took in the third lower portion of the neck. On 
pressing this tumor the colt contracts spasmodically all the 
cervical muscles, stretching out the head or the neck which is 
partially lowered, while at the same time the animal is squeal¬ 
ing loud from pain, coughing and ejecting, through the mouth 
and nostrils, large masses of saliva and mucous. Between 
the spasms the colt swallows saliva, gulping the same with 
difficulty, and gradually filling up the oesophagus from the 
tumor to the pharynx, when another spasm comes on. The 
physiognomy of the colt, during the spasms, is similar to the 
expression of animals during the act of vomiting or nausea. 
Diagnosis .—Constriction of the oesophagus and artificial 
jabot filled with feed. 
Prognosis .—Very serious, perhaps fatal. 
Treatment .—Friction every half hour on the neck along 
the course of the oesophagus, with the following liniment: 
laudanum and fluid extract of belladonna ea. 3 i; gr. 
arnica, ether and camphor spirit, ea. 3 ii; a hypodermic in¬ 
jection of y grain of morphine was made on the left side of 
neck. Half an hour after the second friction the colt seemed 
to be easier and the spasms did not return so frequently. The 
frictions were continued all the night. In the morning, six 
o’clock, the tumor was softer, but still containing feed, the 
muscles relaxed over the tumor; "the animal felt at ease, 
drank water very carefully ; there are no cramps on pressing 
the tumor, even when roughly manipulated. I then injected 
up in the mouth a mixture of ginger tr. 5 ss; tr. gentian,
