too much moisture, such as 3//-grass &c,, are those in which 

 lowered vitality and debility with dropsies occur, such as, 

 water-braxy, shell sickness, and trembles. Low temperature 

 and exposure to cold, winds and rain aggravate these diseases. 

 Moisture within, moisture without, moisture above below 

 and around, must dilute and impoverish the blood and 

 macerate and soften the tissues, disintegrate the cell elements 

 and render them incapable of performing the functions of 

 organic life, and affect the blood cells and the walls of the 

 blood vessels injuriously. Hence the necessity of giving 

 plenty of straw and other dry and also nourishing food in the 

 rains and in the early part of the cold weather. 



1.050. Foods too rich in carbohydrates and fat produce 

 liver disorders and diarrhoea. The blood becomes overladen 

 with their products, and highly plastic, from imperfect oxida- 

 tion, congestion being the result. 



1.051. Foods too rich in proteids produce extravasation of 

 blood into the tissues resulting in inflammations and red- 

 braxy. Milk containing a large amount of proteid matter is 

 a suitable food for young animals, but when it is excessively 

 poor or excessively rich, calves and other young animals suffer 

 from different forms of disease. Milk is again a conveyor of 

 germs and various deliterious matters. Vegetable mineral 

 and animal poisons and diseases such as anthrax may be 

 communicated through the vehicle of 'milk from one animal to 

 another. In the artificial rearing of calves, skim-milk mixed 

 with lime-water, is often found a more suitable nourishment 

 than the rich milk as it comes from the cows' udder. 



1.052. Innutritious food results (i) in indigestion, as 

 animals require a larger quantity of it to get the requisite 

 amount of nourishment or a quantity which taxes the strength 

 of the digestive organs ; (2) in debility for want of sufficient 

 nutrition.

 jurious, as the sand or dirt has the tendency to collect in the
