S74 AZOTURIA. 



are attendant upon the disordered condition. I am well 

 enough aware that this, or any statement, may not explain 

 every sjToptom, or do away with all that is j)iizzling in the 

 varied changes which occur in the process of assimilation 

 during the development of the disease. 



Besides the reception of an extra amount of nutritious 

 material while the body is in a state of quiescence, it seems, if 

 not absolutely needful for the appearance of the symptoms 

 diagnostic of the disease, to be at least highly provocative of 

 it, that this condition of enforced idleness and liberal dietary 

 should be followed by resumption of work moderate or severe, 

 or even exercise ; that, in short, a certain amount of move- 

 ment or activity of function of the different organs of the 

 body be called for. 



I have observed that the use of certain articles of dietary 

 seems more disposed to be followed by an accession of those 

 symptoms characteristic 'of the disorder than others ; that in 

 particular, feeding in large proportion with vetches, tares, and 

 the leguminous foods generally, are very apt to induce this 

 condition. Indeed, upon examination, it would appear that 

 all, or nearly all, cases of azoturia which I have encountered 

 in the Border districts over a number of years, have been 

 directly traceable to full feeding with materials of this class. 



The largest number of attacks amongst agricultural horses is 

 during the autumn, at the period of harvesting the corn crop. 

 At this time the horses are kept longer in the yoke, and are 

 usually liberally fed Avitli ripe tares. The feeding is not con- 

 fined to three or four stated diets, but is continuous, so to 

 speak ; for in addition to receiving oats or mixed grains at 

 regular intervals, the ripe tares are laid before them the Avhole 

 time the carts or waggons are being unladen. Should the 

 state of the Aveather interfere, and the animals be detained in 

 the house, which they usually are, all the time having the 

 same full dietary rich in the leguminous materials, at the end 

 of the week, or even less, when again put to work, the proba- 

 bility is that cases of nitrogenous urine, or ura?mic poisoning, 

 will show themselves. At one time, judging from Avhat I had 

 observed, I was of the opinion that this operation of working, 

 following the rest and repletion, was necessary to induce the 

 toxic condition. Further experience, however, has satisfied
