lung trouble persistently stand in one position, and that 

 position is where they can take most advantage of the 

 fresh air, which is usually near to the door or window. 

 This fact should never be lost sight of in the treatment 

 of lung complaints ; in fact, fresh air is one half the 

 battle in deahng with lung trouble. Experience proves 

 that horses should be kept out in the open air as much as 

 possible, provided that the animal can be kept dry. 

 The open air treatment of pneumonia cannot be too 

 strongly insisted upon ; in fact, all respiratory complaints 

 should be dealt with after the fashion indicated. There 

 is a trite saying, '* Give him air and he'll straight be well." 

 In disease, more particularly that in connection with the 

 lungs, pure air represents food, and it will do more good 

 than all the medicine in the world. In nine cases out of 

 ten pleurisy accompanies pneumonia, which is not to be 

 wondered at, considering that this serous membrane 

 invests the lung structures, being reflected over the lungs 

 as well as lining the cavity of the chest. In the bilious 

 form the predominant symptom is yellowness of the skin 

 and visible mucous membranes. For instance, the lining 

 of the eyelids is yellow, the nasal passage has a yellowish " 

 tint, the cheeks are yellow on their inner side, the mouth 

 is dry and the tongue yellow, the white portion of the 

 eyes is yellow, whilst the pulse is full and slow, the 

 temperature elevated two or three degrees, and the 

 animal is torpid, with httle or no desire for food. Some- 

 times this trouble is spoken of as bilious fever, and is 

 due to the bile pigm^ents entering the circulation. These 

 bilious S3miptoms sometimes persist for several weeks 

 before they show any signs of abatement. The urine is 

 of a deep yellow colour. In the intestinal form of influenza 

 the animal is restless, indicating that there is a certain 

 amount of abdominal pain or colicky disturbance. The 

 stomach and the intestines are very often implicated in 

 the bilious form previously alluded to. When the brain 

 and spinal cord are participating in the disease now
