**All those parts of the Hen which are designed to Generation, 

 namely the Ovary, Infundibulum, the process of the Womb, and 

 the Womb itself, and the Privities: and also the scituation, 

 fabrick, quantity, and Temper of all these, and whatsoever else 

 relates thereto: they are all inservient, and handmaids either to 

 the procreation of the Egge, or to its Augmentation, or else to 

 Coition, and fertility received from the Male, or to the foetus: 

 to which they conduce either necessarily or principally, or as a 

 Causa sine qua non, or some other way to the better being. For 

 there is nothing made either vain or rash in all the operations of 

 Nature." — William Harvey, Anatomical Exercitations Concern- 

 ing the Generation of Living Creatures, 1653.
