RELATIVE INFLUENCE OF PARENTS. 219 



depends upon the comparative physical power and 

 strength of constitution in each parent even more, 

 perhaps, than the composition of the blood. 



" There have been many instances of two brothers 

 being used in the stud, both among horses and grey- 

 hounds, in which one has almost invariably got his 

 stock resembling himself, in all particulars, not even 

 excluding color, while the descendants of the other 

 have rarely been recognizable as his. Thus among 

 horses the Touchstones have been mostly brown or 

 dark bay, and as a lot have shown a high form as 

 race-horses ; while the Launcelots have been of all 

 colors, and have been below mediocrity on the turf. 1 

 Several examples of the same nature may be quoted 

 from among greyhounds, such as Ranter, Gipsey 

 Prince, and Gipsey Royal, three brothers whose stock 

 was as different as possible, but the fact is so gener- 

 ally recognized that it is not necessary to dwell upon 

 it. 



" Now, surely this difference in the power of trans- 

 mitting the likeness of the sire, when the blood is ex- 

 actly the same as it is observed to extend over large 

 numbers, can only depend upon a variation in indi- 

 vidual power. Not only does this apply to the males, 

 but the females also show the same difference." a 



After citing several other instances of such varia- 

 tions, Stonehenge concludes by recommending breed- 

 ers to be guided by his thirteenth axiom, which is as 

 follows : " The purer or less mixed the breed, the 

 more likely it is to be transmitted unaltered to the 



1 Touchstone and Launcelot were full brothers.
