The teeth must, therefore, be properly treated to obviate these difficulties. I have had Dr. E. E. Clark, the celebrated veterinary dentist of New York, operate for me on many occasions, and with wonderful success.’

The man who reads us this lesson styles himself a ‘practical horseshoer.’ But after all, might it not have been the shoeing that had in the first place caused the caries of the teeth, and that this had reacted in its turn upon the feet or other organs of locomotion?

At any rate, Mr. Russell’s experience proves that there is sympathy between the teeth and the heels of a horse, and these are the parts of him that are the most remotely separated.
