One may give for the same purpose injections of arseniate of strychnine, which has the advantage of sustaining the tone of the heart and preventing syncope. The dose should not exceed 1·5 grains in large animals. Finally, a stimulating diet containing milk, alcohol, soup, cooked vegetables, and small quantities of vegetable pulp is useful. With early treatment animals sometimes recover in a few hours. Intravenous or subcutaneous injections of physiological salt solution (2 drachms of sodium chloride in one quart of water) may prove of value when hæmorrhage has been abundant and vascular pressure is low. CHRONIC ENTERITIS (CHRONIC DIARRHŒA). Chronic diarrhœa is common in byres. It appears suddenly, often fails to attract attention, and assumes the form of simple diarrhœa, a fact which accounts for it frequently being described as chronic diarrhœa, dysentery, etc. =Causation= and =pathogeny=. This form of diarrhœa occurs sporadically throughout France, and under exceptional circumstances may permanently attack a number of animals in a given place. The immediate cause is not known, but without doubt the disease is of microbic origin. Like Lignières, Moussu at one time believed that this disease was very probably identical with that known in Argentina under the names of diarrhœa, _entéqué_, or bovine pasteurellosis. The hypothesis has not been verified, and Lignières’ treatment, said by him to have succeeded in Argentina, always failed in Moussu’s hand. [Illustration: $1] The only point which seems admissible is that this disease, which Moussu considered to have analogies with chronic sporadic dysentery in man, is due to one or several organisms, which develop in the intestine and produce toxins, causing diarrhœa, without, however, marked inflammation of the intestinal mucous membrane. =Symptoms.= The onset is often overlooked. The diarrhœa gradually increases without appearing to be very serious; but it persists in varying degrees of intensity. The patients do not appear to suffer, and do not lose their appetite or spirits, but in time the diarrhœa becomes exhausting; they waste, and after some months become excessively thin and poor. Intestinal peristalsis becomes exaggerated without the existence of colic or tympanites. The evacuations are frequent, and little by little the abdomen retracts, until, in horseman’s parlance, “the belly is up to the back,” even in cows of four, seven, and eight years’ bearing. The diarrhœa is serous, always fœtid, and without tenesmus. The fæces may either be very soft or be passed in veritable jets. They are always a little discoloured, and frequently contain grain or undigested forage. They always contain numerous bubbles of gas.
