138 CAUSES, i^YMPTOMS AND TREATMENT OF 



a treatment which was a secret, but he thinks it was the tincture of 

 the chloride of iron which was used. After you arrest the discharge, 

 and some tenderness remains, then a blister is of benefit — and a blister 

 may be of benefit, although there is a sinus present. 



Bruises. — The sensitive sole is liable to bruises, especially upon 

 macadamized roads, where there are rolling stones. This causes more 

 or less lameness, and it is difficult to say just what part is affected ; 

 and there may be extravasation of blood in the sole, somewhat like a 

 corn. A tap with a hammer causes pain ; if more severe, it may be 

 followed by inflammation, suppuration and extreme lameness. Then 

 remove the shoe ; cut down and give exit to the matter. The pincers 

 also aid in finding the seat of lameness in the foot. 



Seedy Toe. — So called because it is generally found in the toe, and 

 the horn breaks or crumbles in small pieces, something like a millet 

 seed. It is due to an impaired secretion, the result of some slight 

 irritation or other, some predisposition, or to some direct cause, as 

 large clip in shoeing, which presses upon the sensitive parts, causing 

 an abnormal secretion. The hoof is easily broken down ; you can 

 even break down the connection between the wall and sole. 



Treatment. — In many cases the horse is not lame, but it is an un- 

 soundness, which may be overlooked. Remove the shoe, cut down the 

 wall and diseased sole, and endeavour to remove the diseased parts. 

 Apply a pledget of tow, saturated with carbolic acid, oil of tar, etc. 

 Overcome the irritation with poultices, hot or cold baths, etc. ; and it 

 is good practice in some cases to blister around the coronet ; or, if you 

 have plenty of time, use cold water. It is not very serious, but it 

 requires some time for the healthy growth to take place. 



False Quarter. — This term is usually applied to any condition 

 where there is an abnormal condition of horn, and it is the result of 

 an injury to the coronary substance. It secretes the horn, and if it 

 is injured, it does not secrete properly. And in some cases there is no 

 secretion from the coronary substance, but from the sensitive laminae 

 only ; or, ir may secrete, but there will be a ridge on either side. This 

 does not do any great harm, but if the only secretion is from the 

 laminae, it is more serious. It may come in any part, most likely to 

 come in the heel. Treatment is not often required. You may rasp it 

 if necessary. This may come from a calk. 



NAVICULAR DISEASE. 



Navicularthritis, Coffin Joint Lameness, etc.— This is common. 

 The parts involved are the navicular bone and the bursa in connection 

 with the perforans tendons. 



Pfl^/jo/o^v— There has been some difference of opinion among emi- 

 nent veterinarians about the pathology of this. Contraction of the 

 foot was supposed to be a disease, and we still hear of it, and it is 

 quite plausible to a person not acquainted with the parts, ^ut the 

 so called specific for this disease will not stand the test when put into 

 practice. Contraction is not a disease, but the result of disease, and 

 especially of navicular disease. Some thirty-five years ago navicular 

 disease was said to be inflammation set up in the navicular bone ; 

 then it was thought that it began in the tendon — Prof. Dick advo- 

 cating that it began in the tendon. Prof. Williams says it commences 

 in the cancellated structure or in the cartilage of navicular bone.
