nut of small value if unsupported by others, which are 

 luckily now of common occurrence, among which the 

 following tends strongly to its corroboration :— In the 

 Philosophical Transactions for 1821, Dr Wollaston 

 relates that D. Giles, Esq., had a sow of the black and 

 white kind, which, after littering by a chestnut boar of 

 the wild breed, was put, some time after the death of 

 this, to boars of quite a different variety, yet the off- 

 spring were covered with chestnut marks, so as closely 

 to resemble the long-departed animal. 



The progeny of most domesticated animals often 

 bear a striking resemblance to the grandmothef or 

 grandfather, and it is well known that the desired 

 changes cannot be effected on a breed, or that the 

 desired breed cannot be produced, till the third, fourth, 

 or even the fifth crossing, so that the importance of 

 having few defects in a stock will be readily admitted, 

 seeing their debasing consequences are carried through 

 whole generations, and that though absent in one 

 remove, yet that they may appear in the next. Both 

 sire and dam should be chosen as free from defects as 

 possible, a thing often neglected in rearing domestic 

 animals, especially horses, where the opinion is in 

 vogue, that no matter how debilitated and worn out 

 may be the dam, yet that if coupled with a young and 

 perfect sire, a healthy handsome offspring will be the 

 issue ; than which idea nothing can be more absurd, as 

 such animals, if left to nature, would seldom or never 

 come in contact, owing to the one party never attain- 

 ing a decripit age, but perishing on its verge.

 result of the relative ages of the parents ; thus, issue
