Sheep,  Goat  12  to  15  . . 70  to  80 
Dog  ..  16  to  18  ..  90  to  100 
These  numbers  vary  of  course  with  age.  A 
young  horse,  for  example,  makes  14  or  15  respira- 
tory movements  per  minute,  whereas  in  an  old  horse 
the  number  may  fall  to  9 or  10.  In  a young 
ox  the  number  is  from  18  to  21,  in  an  old  ox 
it  varies  from  12  to  15.

In  a lately  published  work  on  the  Natural 
History  of  the  animals  of  the  farm  by  Dr.  Georges 
Pennetier,  Director  of  the  Museum  of  Natural 
History  in  Rouen,  the  author  touches  upon  a 
subject  which,  at  various  times  has  aroused 
considerable  discussion.  Dr.  Pennetier  revives 
M.  Thurey’s  theory  according  to  which  the  sex 
of  the  offspring  is  determined  by  the  exact  period 
at  which  the  service  takes  place  ; although, 
however,  he  quotes  the  testimony  of  a breeder 
of  cattle  who  certifies  that  in  the  course  of 
twenty-nine  experiments  there  was  not  one  failure 
in  securing  the  desired  end,  it  is  evident  that 
the  author  still  regards  the  problem  as  unsolved.  »
