Chloe B (No. 7) at the end of her 1910 lactation period developed 

 an abscess between the quarters of her udder, which healed leaving 

 a hard lump. This lump was still plainly evident at the time of 

 her calving in 1911 but had entirely disappeared before she was 

 sold in November, 1911. See pp. 144-152. 



Dolly F. B. B. (No. 8) aborted her first calf on July 7, 1910, but 

 her second and all later calvings have been normal.
