and less able to resist tlie attacks of it. Alternations between heat 

 and cold, more commonly from cold to heat than the reverse, are 

 alike productive of congestion. 



Congestion of the lungs is seldom ushered in by any premonitory 

 symptoms, excepting that the animal is sluggish when at work, or 

 that he is off his feed. The patient begins to breathe laboriously (to 

 blow) ; the extremities are intensely cold, the visible mucous mem- 

 branes are red and injected, and the pulse is accelerated ; sometimes 

 a dry cough and constipation are present. As the disease advances, 

 the mucous membranes assume a leaden hue, the breathing becomes 

 very laborious ; the patient lies down and continually looks round 

 at his sides, and, when up, stands with his legs outstretched and 

 wide apart ; the pulse becoming more irregular and oppressed, the 

 teeth grate, the mouth gets cold, and the extremities swell ; and 

 often within three days from the cause of the malady coming into 

 operation death ensues. 



To prevent is better than to cure ; therefore, in bringing up a 

 young horse from grass, previously to submitting him to work, 

 prepare him by gradually introducing him to it. Give a moderate 

 allowance of hay, and commence with one feed of oats, and 

 gradually increase it to three ; carrots two or three per diem ; no 

 beans; and, if necessary, a gentle dose of purgative medicine. Allow 

 walking exercise at first, and from week to week increase the pace, 

 but do not commence by exerting him to the utmost during the first 

 month. As treatment, give food easy of digestion, such as boiled 

 bran, oats, and carrots ; clothe the patient, bandage the legs with 

 flannel bandages, apply mustard plaisters to the sides of the chest, 

 and administer every four hours drachm doses of the carbonate of 

 ammonia, and the same quantity of aether, in a pint of water ; if 

 the symptoms subside and constipation sets in, give a small dose 

 of aloes (two drachms), together with a little nitre, but still continue 

 the administration of the above prescribed stimulants, diminishing 

 only the quantity gradually until such time as they can be replaced 

 by tonics. Exercise regularly, and apply plenty of friction to the 

 skin. Sometimes, after recovering from congestion of the lungs, 

 diseases of a low typhoid character supervene, and of course require 

 different treatment. 



CONTEACTED FEET. 



As regards the bad effect of heat and drought, the removal of the 

 cause will effect the remedy. But never allow a horse to stand on 

 fermenting litter. When in the stable stop the animal's feet with
