[1] See note on page 47, relating to “An old operation for spavin.” How Bishoping is Done. Bishoping is dental forgery, false marks being made on the incisor teeth to make an old horse appear young. It is a dishonest practise and not to be countenanced for a moment by a reputable horseman. The modus operandi of the business is told as follows in a well-known book on “Animal Dentistry”: “Renewal of the cups (bishoping) is the most important of the artificial attempts to make horses appear younger, and if performed intelligently upon horses that are not too old, together with the shortening and polishing of the crowns of the superior incisors, may deceive even the vaunted expert. The operation consists of cutting large cups in the inferior corners, smaller ones in the laterals and mere dots in the centrals and then staining them with silver nitrate. The cupping process is performed with an engraver’s gouge, and a revolving hand drill, or by the modern ingenious implement in vogue in the Chicago market, consisting of the foot engine used by human dentists, equipped with a circular cutting wheel, by which cups of perfectly normal shape and size can be made. The horse is backed into a single stall and secured in a dental halter. An assistant works the dental engine with the foot. The operator holding the hand piece of the flexible shaft in the right hand and the jaw in the other, cuts first a large elliptical cup, with sharp commissures, in the table of the corner incisors, then smaller ones in the laterals and small dots in the centrals. As the wheel revolves with great velocity, the cupping is the work of but a moment, if the horse stands complacently. When the corner tooth has but a small table it is enlarged by filling and the cup is cut across its entire length. The cup in the corners is frequently made with a rounded belly internally and a sharp commissure externally to give a more confusing if not a more natural appearance. When the cupping process is complete, the arcade is dried and kept free from saliva by wrapping the jaw behind the teeth with a cloth or towel. The cups are then stained by applying a saturated solution of silver nitrate with a stick and then drying it immediately by plunging the head of a burning match into it. The drying process immediately blackens the cavity. If the stain flows over the table of the tooth it is filed off.
