FEMALE ORGANS. J 91 



Of the first of this class is the moth * and butterfly ; of the second, the 

 beetle 2 . The structure of such eggs I have not yet ascertained. 



Of the Oviducts. 



All oviparous animals 3 have one or two oviducts. Fowls have one, 

 The amphibia and lizard-kind have two. These have nothing like a uterus 

 or a vagina, and have a common passage to the oviducts and rectum. 



Oviparity belongs to the inferior order of animals, both as to powers 

 or principle, and as to size. 



Of the Fallopian Tubes. 

 If we consider the use of the fallopian tube in animals, where its use 

 is very evident, and then apply that use to where it is not so self- 

 evident, we shall be led, in some measure, to infer the same use to it in 

 them also, although, perhaps, not to the same extent of use. All the 

 viviparous classes have them. Many of the oviparous have them, and 

 many are without them. It is in the oviparous that we are to examine 

 their use, and then apply that to the viviparous 4 . 



Double Uterus. 



Many animals have two uteri, viz. the rabbit 5 , a particular kind of 

 hog called the ' peccari,' ' Le Cabiai 8 ,' &c. 



Of the Uterus. 



The operations of the uterus, when impregnated, do not go on in all 

 parts of that viscus at the same time, but only where the foetus is. For 

 example, the increase of size of vessels, the alteration in the structure 

 of the uterus itself, both of which appear to depend on the increase of 

 the size of the uterus, do not take place save at those parts which are 

 distended by the increased growth of the foetus 7 .

 roe-fish.]

 ' oviducts ' in oviparous Vertebrata possessing them. They transmit the ovarian 

 ovum, and add material to it.]
