1 shall not venture, however, for the reasons which have been 

 stated, to lay down any precise rules either respecting the quantity of 

 water that should be allowed to Horses, or the periods at which it 

 should be given. But will content myself with observing, that we 

 shall be safe in adhering to the general directions which have been 

 given, or rather the suggestions that have been thrown out, upon 

 both these points. 



After these observations, I proceed to make some remarks upon 

 the quality of waters. And as 1 know of no better authority on the 

 qualities of common water, than that of Dr. Thomson, I shall 

 venture to quote freely some remarks of that Philosopher, on this 

 important branch of my subject. 



Good water, as this ingenious Chemist has observed, is as transpa- 

 rent as christal and entirely colourless. It has no smell, and scarcely 

 any taste, and, in general, the lighter it is, .so much (iie better. 

 The waters used for the common purposes of life may be reduced 

 under four heads, namely 1st rain water, 2nd .spring and river water, 

 3rd well water, and 4th lake water. Rain water, unless when near 

 a town or collected at the commencement of the rain, possesses 

 the properties of good water in perfection, and is as free from 

 foreign ingredients, as any native water whatever. And I can add 

 from my own experience, that, even though it be caught under (he 

 disadvantage of falling in a large city, if it be collected in a cistern, 

 wherp after a time it will deposit its impurities, it has considerable 

 superiority over most of the waters of springs, in forwarding the 

 condition of Horses. For, though the water of springs is, in fac^.
