 not likely to be born alive before the fiftieth day, though 

 they may be delayed several days without any apparent

 tion is about sixty-three days. 



There is room for the greatest discretion in the man- 

 agement of the brood bitch, and common sense with a few 

 guiding scientific principles are worth volumes of rules 

 without reasons, for no two cases precisely resemble each

For the first month there is so little change in the
