Fat  Determination  in  Milk,  Cream,  etc. — Place  5  cc.  cream  or  10  cc. 
milk  (carefully  measured)  into  a  test-glass  of  50  cc.  capacity  graduated 
into  Jo  cc,  add  10  cc.  concentrated  hydrochloric  acid,  boil  while  rotat- 
ing the  liquid  and  agitate  the  cold  dark-brown  fluid  with  30  cc.  ether. 
After  this  separates  clearly  read  ofP  the  volume  of  the  ethereal  layer, 
remove  10  cc.  ^vith  a  pipette,  allow  to  flow  into  a  tared  porcelain  cruci- 
ble, evaporate  on  a  water-bath,  dry  in  an  air-bath  at  100°  and  weigh. 
Calculate  the  weight  for  the  volume  read  ofl".  This  determination  can 
be  made  in  about  15  minutes  and  the  results  do  not  difler  by  O'l  per 
cent,  from  those  gotten  by  other  quantitative  methods. — Dr.  W.
