652 CYCLOPEDIA OF LIVE STOCK AND COMPLETE STOCK DOCTOB. 



Favorite (by Foljaiube) and of young Pha?nix (by Favorite, her son, 

 upon his own mother,) the dam of Comet 155, so celebrated as having 

 been sold for 1000 guineas ($5000,) also by Favorite, a specimen of as 

 close in-and-in breeding as can perhaps be found on record." 



As an example of wonderful depth of in breeding with continued 

 good results, the cow Clarissa may be mentioned. She possessed 

 sixty-three sixty-fourths of the blood of Favorite. Her pedigree runs 

 thus : " Cow Clarissa, roan, calved in 1814 ; bred l)y Mr. R. Colling, got 

 by Wellington (080) out of— by F'avorite, (852)— by Favorite,— by 

 F'avorite — by Favorite — by Favorite — by Favorite — l)y a son of Hui)- 

 back . ' ' 



Wellington, the sire of Clarissa, was also deei)ly in-bred with the blood 

 of Favorite. Taking the two ])edigrees — that of Clarissa and Welling- 

 ton together — they will read thus : 



1. Bull, Hubback. 10. 6th cow ))y Favorite. 



2. Son of Hub])ack. 11. Clarissa. 



3. Cow, by son of Hubback. 12. Bull Wellington, sire of Clarissa. 



4. Bull, F^avorite. 13. Bull, Comet. 



5. 1st cow by Favorite. 14. Cow, AVildair. 



6. 2nd cow by Favorite. 15. Cow, Young Phoenix. 



7. 3rd cow by F^avorite. 16. Cow Phcenix. 



8. 4th cow by Favorite. 4. Same bull Favorite on the side 



of Clarissa's sire as on the 

 side of her dam. 



9. 5th cow l)y Favorite. 17. Bull, Bolingbroke. 



18. Granddaughter of Hubback. 

 There ought to be no fear of following where such results have been 

 attained by others, and these the most eminent and successful breeders 

 of their day. The best successes since their day have also been obtained 

 by continuing the same course to such a degree as intelligent observation 

 showed to be practical)le, and especially by breeding in line. 



XIX. The Gestation of Cows. 



Some years since the writer collected a number of facts in relation to 

 gestation and the influence of the varying times of gestation on the 

 young, to refute a prevalent idea that protracted gestation produced 

 males. Mr. Tessier, for forty years an accurate and acute observer of 

 various animals, gives results in the case of over 575 cows, and these 

 subsequently having been exi;ended to 1,131 cows the extremes were not 

 changed, but results as to averages are as stated below. 



Earl Spencer also carefully tabulated the period of gestation of 766 

 cows, the least period being 220 days ; the mean 285 days ; and the long-
