This is rarely of grave consequence in cattle, and when it exists, is usually a symptom of some other disease. When present, a dose of twenty drops of the J. K., given morning and night, will soon set all right again. If there is suspicion of some inflammatory condition lurking in the system, the A. A., in like doses, will have the like effect. Tympanitis—Hoove—Blown—Drum-Belly—Grain-Sick—Heaving of the Flanks—Maw Bound This disorder—of very frequent occurrence among cattle, though not belonging exclusively to them—is of two kinds; one due to the evolution of gas from the food taken, the other to the impaction of the food. In one case the gas produces enormous inflation of the rumen, or first of the four stomachs possessed by cattle, in the other distension. DIAGNOSIS.—To Mr. Surmon we are indebted for the following table of DIFFERENCES BETWEEN DISTENSION FROM GAS AND FOOD ──────────────────────────────────┬────────────────────────────────── DISTENTION FROM GAS │ DISTENTION FROM IMPACTED FOOD ──────────────────────────────────┼────────────────────────────────── The left flank, on pressure, feels│The left flank, on pressure, feels soft, elastic and yielding to the │solid; does not yield readily to fingers.

Wet grass in warm weather, or fodder that has become heated in consequence of being heaped together while damp, may also be too freely eaten. The consequence is that the rumen is overloaded, and the contents, under the influence of warmth and moisture, ferment and evolve what is at first carburetted hydrogen; and subsequently sulphuretted hydrogen; or, if there be no formation of gas, the food remains solid and undigested. Drinking excessively of cold water, eating too much bran, chaff, unboiled potatoes, uncrushed oats, grains, boiled roots or turnips, may cause the same condition.
