TYMPANITES IN AN OX—VOMITING OF A HAIR-BALL. 
R. was called to see an ox which had suddenly swollen up 
to an alarming extent, and seemed to be in extremis. While 
preparing appropriate therapeutic agents, the animal fell and 
made violent efforts to vomit. In the act of vomiting that 
subsequently occurred, a small quantity of chewed hay and a 
hair-ball were expressed. 
The animal recovered immediately. The circumference 
of the hair ball measured twenty cm.; the periphery was hard 
and smooth.— Schweiz. Arch. Thlk.
