 are liable to disease and deformity. 



Light, therefore, is a condition of vital activity ; and in 

 view only of preserving the sight of animals, it is absolutely 

 necessary that, while they are in the barn, their optics shall 

 have free access to the sun's rays. 



If a cow were in the same condition as a polype, with no 

 organ of vision, who shuns light, a dark bam might prove to 

 be its earthly paradise ; but as the cow has special organs of 

 vision, evidently susceptible to the influence of light, and the 

 integrity of its organism or a part of the same, depending 

 entirely on the admission of light, it is absolutely necessary 

 that barns should be constructed accordingly. 



DIARRHCEA IN CALVES. 



Diarrhoea is a very prevalent disease among calves. The 

 suckling calf is liable to be the subject of this affection, when- 

 ever the general health of the parent is impaired. In such 

 cases the mother is to be treated instead of the calf; she, prob-

The disease occasionally occurs in consequence of weaning

 be treated as follows : let the calf have two ounces of phos- 

 phate of lime, two drachms of carbonate of soda, and a quai't 

 of scalded milk; mix the same, and administer by means of a 

 drenching horn, or bottle. It may be divided into " broken " 

 doses, or may be given at once, as a single dose. 



If the above remedies fail in arresting the diarrhoea, I should
