several times daily. 11' the lameness persists uiulor this uiiKl (ourse 

 of treatment, it must, of course, be attacked l>v other methods, and wo 

 must resort to tlie cantharides ointment oi* Spanisli-fly blister, as we 

 have before recommended, pjcsidcs thi>, and producin<; an analogous 

 effect, the compounils of biniodid di" nu rciiiv aic favorecl by some. 

 It is prepared in the form of an ointment, consisliiii; of 1 diam of the 

 biniodid to 1 ounce of either lard or vaseline. It forms an excellent 

 blistering; and alterative application, and is of special advanta^ic in 

 newly foiincd or recently discovered exostosis. 



It remains a pertinent (juerv. however, and one \vhi«h seems to bo 

 easily answered, whether a tinnor so diminiitixc in size that it can 

 be iletected only by diliuent seaich. and wjiich is neither a disfij^ure- 

 nunt nor an obstruction to the motion of the limb, need receive any 

 recogn^itiiin whatever. Other modes of treatment for splints are rec- 

 ommended and ])racticed w hich belon«z strictly to the domain of oper- 

 ative veterinary surjreiy: amon^ these are to be reckoned actual 

 cauterization, or the application of the fire iron and the operati(m of 

 periosteotcmy. These are frecpiently indicated in the treatment of 

 splints which have resisted milder means.

RINGBONES. 



Kingbone is the designation of the exostosis which is found on 

 the coronet and in the digital and phalangeal regions. (See Plate 

 XXVI.) The name is appropriate, becau.se the growth extends quite 

 around the coronet, which it encircles in the manner of a ring, or per- 

 haps because it often forms upon the back of that bone a regular 

 osseous arch, through which the back tendons obtain a passage. The 

 places wliere these growths are usually developed have caused their 

 .subdivision and classification into three varieties, with the designa- 

 tions of high, middle, and low. though much can be said as to the 

 importance of the distinction. It is true that the ringbone or phalan- 

 ireal exostosis mav be found at various i)oints on the foot, in one case 

 •forming a large bunch on the upper part and quite close to the fet- 

 lock joint: in another around the upper border of the hoof, or per- 

 haps on the extreme front <»r on the very back of the coronet. The 

 shape in whi<h they commonly appear is fav«tr:ible t<> their easy dis-
