love, and the method used by divers animals to make 

 use of their organs according to the commandment of 

 nature. There remain for consideration the lesser 

 mammals and other vertebrates whose fecundatory in- 

 struments resemble those of mammifera. 



In man and other placentaires, the forked prong is 

 a teratological fact only encountered in incomplete double 

 monsters. It is, on the contrary, the most general form 

 among marsupials. A double vagina corresponds to this 

 penis, double at least from the gland, thus in kangaroo 

 and opossum. This original biparity is found regularly 

 in the uterus of certain placentaires, hares, rats, bats, 

 carnivora. The uterus of marsupials is simple without 

 narrowing of the throat. One knows that their young 

 stay there but a short time, that they are born not as 

 foetus but as germs, and complete their development in 

 the marsupial pouch. An opossum, destined to attain 

 about the size of a cat, is at birth about bean-size. 

 These animals, therefore, differ profoundly from other 

 mammifera. 



Some reptiles, like crocodiles and most chelonians, 

 have only a simple prong; some tortoises have a forked 

 tip to the penis, it is many-branched in the trionix, 

 carnivorous tortoise rightly called ferocious. The 

 saurians and ophidians can deploy outside the cloaca two 

 erectile prongs; in saurians, lizards, they are short, round 

 and bristle with prickles. The females have no clitoris 

 save when the male has a single prong; at least the 

 clitoris is only well constituted in crocodilians and 

 chelonians. 



Copulation is unknown to batrachians, whose contact
