"I told her to spring up and down so as to kick her heels against her buttocks, and when she had sprung for the seventh time, the seed ran out on to the ground with a noise, and the girl on seeing it gazed at it and was amazed. [...] It was as if someone had removed the external shell of a raw egg, and the fluid part inside was visible through the internal membrane. [...] It was red and roundish; broad, white strands were seen to be present inside the membrane, pressed together with thick, red serum, and around the membrane on the outside there was bloody material. Through the middle of the membrane something narrow came out, which appeared to me to be an umbilical cord, and through this the movement of breath in and out first took place. From this the membrane spread out and completely enclosed the seed. This is how I saw the seed to be on the sixth day."
