ANEMIA, HYDRiEMIA, OLIGEMIA. 



These terms are applied to that condition of the system in 

 which there is a deficiency and poverty of the blood, a state 

 brought about by loss of blood (haemorrhage), profuse discharges 

 of any of the natural fluids of the body, as those of diarrhoea or 

 diabetes, in which it seems as if the blood globules were melted 

 down to supply the profuse discharge ; insufficient food, de- 

 privation of fresh air, exhausting diseases, and the action of some 

 deleterious agents, as witnessed in horses kept in ill- ventilated 

 stables, or suffering from the influence of the glanders poison. 



The symptoms of ansemia are paleness of the visible mucous 

 membranes, with often an unhealthy or slate-coloured appearance 

 of that of the nasal cavity. In some instances a coppery appear- 

 ance is witnessed; this is undoubtedly due to an altered con- 

 dition of the globules, and a disordered state of the powers by 

 "which they are formed ; the conjunctiva is pale, the mouth cool, 

 and the tongue generally unnaturally soft. Young, growing 

 animals, insufficiently fed and improperly cared for, exjDosed to 

 the vicissitudes of the w^eather during the winter mouths, are 

 reduced to an anggmic condition, manifested by emaciation, 

 debility, and often a depraved appetite. When thus reduced, 

 great care is to be taken that such are not suddenly turned 

 into rich pastures, for it seems that the process of the forma- 

 tion and elaboration of the blood, and the organs concerned in 

 it, are in such a state of disorder from long disuse, that the 

 alimentary matters contained in luxuriant grass or nourishing 

 food are transformed into an imperfect blood-plasma, — that is to
