5. In fome cafes by the nutriment originally do- 

 pofited by the mother the filament acquires parts not 

 exactly firnilar to thofe of the father, as in the pro- 

 du&ion of mules and mulattoes. In other cafes, the 

 deficiency of this original nutriment caufes deficien- 

 cies of the extreme parts of the fetus, which are laft 

 formed; as the fingers, toes, lips. In other cafes, 

 a duplicature of limbs are caufed by the fuper- 

 abundance of this original nutritive fluid, as in the 

 double yolks of eggs, and the chickens from them 

 with four legs and four wings. But the production 

 of other monfters, as thole with two heads, or with 

 parts placed in wrong fituations, feems to arife from 

 the imagination of the father being in lome manner 

 imitated by the extreme veflels of the feminal 

 glands ; as the colours of the fpots on eggs, and the 

 change of the colour of the hair and feathers of ani- 

 mals by domeftication, may be caufed in the fame 

 manner by the imagination ot the mother. 



6- The living filament is a part of the father, and 

 has therefore certain propenfnies, or appetencies, 

 which belong to him ; which may have been gradu- 

 ally acquired during a million of generations, even 

 from rhe infancy of the habitable earth ; and which 

 now poifeiTes fuch properties, as would render, by 

 the appofition of nutritious particles, the new fetus 

 exadtiy fimilar to the father ; as occurs in the buds 

 and bulbs of vegetables, and in the polypus, and 

 tsenia or tape-worm. But as the fii ft nutriment is 

 fupplied by the mother, and therefore refembles fuch 

 nutritive particles, as have been ufed for her own 

 nutriment or growth, the progeny takes in part of 

 the likenefs of the mother.
