When the air interchange between the lungs and the abdominal air sacs in 10 adult fowls were intercepted completely with the alon-alpher medical adhession for 20 to 70 days, an increase of respiratory counts and a decrease of the comb were observed. The weights of the testes decreased remarkably to 0.5 to 1.9g, showing no sperm. Thirty-five to sixty days after air-interception between the lungs and the abdominal air sacs, one testis was extracted, weighing 0.55 to 1.9 g, and no sperm was observed. At the same time after the air-interception, air interchange between the lungs and the abdominal air sacs was resumed by taking off the alon-alpher adhession. After 30 to 96 days, a decrease in the respiratory counts and an increase in body temperature were observed. The weight of the testes increased up to 3.45 to 8.7g, showing many sperms. In these results, it might be presumed that the temperature in the abdominal air sacs is lower than the rectal temperature the latter being caused by the flow of air from the lungs to the abdominal air sacs. In consequence, the authors concluded that the abdominal air sac relates to the physiological function of direct respiratory function, and effects the cooling of the testes in the scrotum.
