wherefore many persons suppose that the female is impreg- 

 nated by swallowing the semen of the male ; and they have 

 been frequently observed to do this. This is seen at the 

 season of coition, when the females follow the males, and are 

 observed to strike them on the abdomen with their mouths, 

 this causes the males to eject their semen more rapidly. 

 The males do the same with the ova of the females, for they 

 swallow them as they are extruded, and the fish are born 

 from those ova which remain. 



6. In Phoenicia they use each sex for capturing the other ; 

 for having taken the male cestreus, they entice the females 

 with it, and so enclose them in a net. They use the females 

 in the same way for catching the males. The frequent obser- 

 vation of these circumstances appears to corroborate this 

 manner of intercourse among them. Quadrupeds also do 

 the same thing, for at the season of coition both sexes emit 

 a fluid, and smell to each other's pudenda. 



7. And if the wind blows from the cock partridge to 

 the hen, these last are impregnated ; and often, if they hear 

 the voice of the cock when they are inclined for sexual 

 intercourse, or if he flies over them, they become pregnant 

 from the breath of the cock. During the act of intercourse, 

 both sexes open their mouths, and protrude their tongues. 

 The true intercourse of oviparous fish is rarely observed, 

 from the rapidity with which the act is accomplished ; for 

 their intercourse has been observed to take place in the 

 manner described. 



CHAPTER Y. 



1. ALL the malacia, as the polypus, sepia, and teuthis, 

 approach each other in the same manner, for they are united 

 mouth to mouth ; the tentacula of one sex being adapted to 

 those of the other ; for when the polypus has fixed the part 

 called the head upon the ground, it extends its tentacula, 

 which the other adapts to the expansion of its tentacula, 

 and they make their acetabula answer together. And some 

 persons say that the male has an organ like a penis in that 

 one of its tentacula which contains the two largest aceta- 

 bula. This organ is sinewy, as far as the middle of the ten- 

 taculum, and they say that it is all inserted into the nostril 

 of the female.
