Abstract: The effect of morphine, Tinct. opii, loperamide, pethidine and atropine on intestinal transit and the faecal and urinary excretion of water and electrolytes was studied in ponies. The rate of passage of a particulate marker was slowed by morphine, hastened then slowed by loperamide and Tinct. opii, and hastened by atropine. The liquid marker was slowed by Tinct. opii and hastened then slowed by the other drugs. Only loperamide decreased the faecal sodium excretion. This drug also decreased faecal water and weight; it appeared worthy of clinical trial in diarrhoea. Tinct. opii decreased by morphine, pethidine and atropine increased faecal water.

Abstract: SUMMARY The ability of 10 horses to hear frequencies between 14 and 25 Kc/s was tested. The horses appeared to perceive ultrasounds by showing either fright reactions or Pryer reflexes to all of the 12 frequencies. The highest frequencies were heard less by older animals, and elicited more reactions in geldings than in mares. RÉSUMÉ Le pouvoir auditif de 10 chevaux à entendre des fréquences comprises entre 14 et 25 kilocycles a étééprouvée. Les chevaux semblent percevoir des ultrasons en réagissant par des attitudes de frayeur ou par des réflexes de PRYER à toutes les fréquences étudiées. Les fréquences les plus élevées sont perues moins facilement par les chevaux agés et provoquèrent des réactions plus vives chez les hongres que chez les juments. ZUSAMMENFASSUNG Bei 10 Pferden wurde die Fähigkeit untersucht, Frequenzen zwischen 14 und 25 Kc/sec zu hören. Die Pferde schienen Ultraschall hören zu können: sie manifestierten Angst oder Pryer-Reflexe bei allen 12 Frequenzen. Die höchsten Frequenzen konnten von älteren Tieren weniger gut wahrgenommen werden; sie riefen auch bei Wallachen stärkere Reaktionen hervor als bei Stuten.
