out a bead of pus. Cutting down the swelling and breaking 
through the tissues with the fingers forty-eight chondroids were 
extracted. The guttural pouches were syringed with permanga¬ 
nate, and belladonna electuary given frequently. After several 
days 74 more chondroids were removed, making a total of 
113 chondroids extracted, and weighing 26 ounces. The largest 
chondroid weighed 6F? drams. There was also washed a pint of 
thick, white substance. Recovery was complete after a short 
time.— ( Journ. of Com. Pathol, and Therapeut.) 
Differential Diagnosis Between Torsion and Simple 
Impaction of the Pelvic Fluxure of the Colon [H. Caul- 
ton Reeks, F.R.C.VS .].—In a long and very interesting article, 
illustrated by valuable photographs, the author presents the fol¬ 
lowing important points as a means of differential diagnosis: 
In Impaction. —-1. Periods of ease, manifested by the the pa¬ 
tient maintaining a sleepy, stretched-out position, on the floor for 
quite long periods. 2. Pulse full and normal in number of beats, 
- except during the paroxysms of pain. 3. Respirations deep and 
regular, only becoming quickened and catchy during pain. 4. 
Temperature normal. 5. No straining on rectal examination. 
Rectum ballooned. No marked spasmodic condition of its walls. 
6. Rectal examination reveals the presence in the pelvis of the 
ingesta—packed in pelvic flexure. 
In Twist .— 1. Constant pain exhibited by continual crouch¬ 
ing movements and marked disinclination to lie down. A dog¬ 
like attitude when down and frequent twinges of acute pain. 2. 
Pulse constantly weak, quick, and slowly progressing to a run¬ 
ning-down character. 3. Respirations short, catchy and labored 
or sobbing. 4. Temperature raised to 103° F. 5. Marked 
straining on rectal examination, with spasmodic clasping of the 
bowel on the inserted arm. 6. The pelvic flexure is altogether 
missing from its position in the left flank.— (Journ. of Comp. 
Pat ho. and Thera.) 
Impaction of the Small Intestine in a Horse [C. N. 
Meyers, L.V.Sc .].—This pony was in pain since twelve hours. 
Visible mucous membranes injected; pulse, 50; temperature, 102° 
F. Little peristalsis of the intestines ; no apparent tympanitis. 
Bladder distended and large quantity of urine taken away. Rectal 
examination reveals hard faeces on the left side. Treatment was 
negative. Post mortem showed gaseous distension of stomach
