roots is : the pulp comes in contact with and gives up a 

 proportion of its moisture to the masticated grain or hay 

 when mixed therewith in the stomach. If not mixed \vith 

 the drier feed, the moisture of root feed is of little if any 

 more advantage than water in a separate form. When 

 roots are sliced or pulped, and evenly mixed through the 

 dry feed, their watery substance adds much to quantity of 

 blood, and this probably facilitates the distribution of the 

 nourishment afforded by the grain or other dry feed, in 

 either sheep or cattle, and imparts juiciness to the meat. 



When much oil escapes through the skin, the meat of 

 the animal will be less oily than when most or all of the 

 fat or oil of the feed is retained within its substance. It 

 should have been said, when speaking of the head, that 

 the expression of the face in cattle indicates the state of 

 feeling comfortable or otherwise. A comfortable, satisfied 

 expression of face and eye indicates good health, which 

 is, also, co-existent with good appetite, digestion, and cir- 

 culation, neither of which is possible, however, without 

 plenty of good air for breathing, and sufficient daily exer- 

 cise to maintain the vigor and extent of the muscular sys- 

 tem, while the blood is completed and made vital as it 

 swiftly passes through the lungs. 



"Animal odors," and "animal heat," are designations 

 much employed in dairy regions. But as the "odors" 

 are caused by free gases, such as carburetted hydrogen, 

 etc., passing sometimes from the bowels through their 

 membranes into the cavity of the abdomen, where they 

 are recognized, in opening the carcass; and may also pass 

 into the blood through the membranes of the arteries, and 

 be recognized sometimes in the milk. The odors are not 

 ijroduced in the animal tissues ; but may be called gas 

 odors. Animal heat, so called, is simply liberated heat — 

 named blood heat on the thermometer — which is set free
