    EXPERIMENT XVII. Opened a doe the third day after the coitus: the pouting parts of the corpora lutea very transparent before the uterus Was touched; but as soon as the spermatic and hypogastric arteries were divided, in order to cut out the uterus, they all, as if struck with some shock like electricity, became opaque. The pouting part I believe is the ovum, and stands upon the top of corpus luteum; it is very vascular, particularly at its basis, but as soon as perfect, or ready for expulsion, carries no red blood; it continues to grow of itself in utero, without adhering to the uterus for two or three days, then takes root, and becomes very vascular: nothing in the tubes or uterus. 4 EXPERIMENT XVIII. Opened another the fourth day in the morning; but it had not conceived, and was in the state of one hot. EXPERIMENT XIX. Opened one in the evening of the fourth day: the appear¬ ances were little different from those of the fifth morning; the ova were only less dispersed through the uterus, and all accu¬ mulated about the orifice of the tubes; the amnion was like¬ wise closer to the chorion. EXPERIMENT XX, Opened another at the end of the third day, or rather on the beginning of the fourth: the ovaria were dark brown; the fallopian tubes and uterus almost black, from the great quan¬ tity of blood derived to them at this time; I opened this uterus
