lo VENTILATION AND LIGHT. 



From the exterior of such premises you may judge of the 

 state of the interior, which on entering will be found to be 

 filled with unpleasant odours, the thermometer standing at 

 seventy in the depth of winter, whilst on all sides not 

 only the olfactory nerves but the eyes are assailed by the 

 effects of ammoniacal gas produced by the imprisoned 

 ordure and urine. 



The sensation is one to make the visitor only anxious to 

 escape into the open air once more. If we are to judge, then, 

 by the result produced upon the human being by contact for 

 a few minutes only with the contaminated air that pervades 

 the whole place ; what must be the feeling of the wretched 

 horse that has to live in it, or rather to die by inches, or 

 become blind from such pernicious treatment ? 



To a superficial observer, and even at times to owners, 

 this state of things has a fascinating attraction. The 

 horses appear with coats like satin, full of flabby fat (engen- 

 dered by heat) often mistaken for muscle. Such people never 

 think of the w^eakness, the languor, the loss of appetite, 

 from which the poor horses are suffering, as the result of 

 continually inhaling and re-breathing the same poisoned 

 atmosphere ; every day, and day by day intensifying its 

 more deadly effects on animal existence. Pearl-like drops 

 are seen in countless numbers standing on most projections, 

 even on the hairs of the rugs, on the side walls, the ceiling ; 

 in fact, every particle of the furniture of the stables is wet 

 and clammy with the same impurely heated air. 



My own views on the question of ventilation are embodied 

 in a book on this subject, which I remember to have read 

 some twenty years ago. It is entitled Practical Ventilation, 

 by R. S. Burns, and I cannot do better than here submit 

 an extract from it : —
