every half hour. After the third injection the colics subsided,

evacuation of hard balls of manure. A low diet, with farina¬

THE PRINCIPLES AND PRACTICE OF VETERINARY MEDICINE.— 
By Professor W. Williams.— Sixth Edition, revised by the author, assist¬

We have none but words of commendation to offer in be-
