VETERINARY JURISPRUDENCE.

by the respiration of animals , a portion of oxygen is withdrawn, 
and a corresponding portion of carbonic acid gas is substituted 
in its place. By the respiration of plants the carbonic acid is 
withdrawn, and an equivalent portion of oxygen substituted ; so 
that, by the mutual action of the members of the animal and 
vegetable kingdoms, the balance of the constituent elements of 
the atmosphere is maintained. 
The blood requires pure air as its food ; the first effect of the 
air is to remove the carbonic acid, which the venous blood takes 
up in the circulation, and when this is effected the properties of 
the blood become instantly changed. In the commencement of 
this process the air is the active agent, and removes the carbonic 
acid from the circulation ; but when this is effected, the blood 
then becomes the acting power, and attracts a portion of the at¬ 
mosphere. The pure air , or at least it ought to be so, then oc¬ 
cupies the place of the carbonic acid , which is just removed.

WaTMORE V. PoCKLINGTON. 
Is he restive ? 
This was an action, tried at the last Lincoln Assizes, for the 
difference between the original price of a horse, and that which 
he fetched when sold at Tattersall’s ; and also for the expenses, 
8cc. He had been warranted sound, and free from vice; and 
the plaintiff 1 gave notice of return on the ground that he was 
restive and lame, from a horny growth on the off fore foot. 
Thomas Field was plaintiff’s groom. He met defendant at 
Cox’s, the horsebreaker, on Wednesday the 7th of August, 18*33. 
The horse was bridled, and led out of the stable. He looked 
him over, and saw nothing the matter with him : he was then 
taken into the stable to be saddled ; did not stand saddling well; 
but one man standing on one side, and a second on the other 
side, and a third holding his head, he was at length saddled. 
They said that he had not been out of the stable for some time. 
They took him out, and led him along the yard once or twice, 
and then one of Cox’s grooms was lifted on him. The horse 
immediately set up his back, but they walked him once or twice 
round the yard. W itness then got upon him, and found him 
very raw in action, and that he did not answer well to the rein. 
He rode with a double rein. He was cautioned not to use the 
spur, nor to ride him far, nor to make him sweat, for he had 
been in physic. Did not ride him long. 
His master bought him, and put him under his care. The
