together through the leg, from which they derive the denomination 

 of pegged " (Solletjsel). It is generally thought that a bony com- 

 munication exists between these " pegged " splints, and that 

 pressure exerted by this bony communication on the suspen- 

 sory ligament, is the cause of the frequent and often inveterate 

 lameness which accompanies this condition. Actual dissections 

 on the dead animal convince me that such a bony communication 

 between the two splints seldom exists, and that the interference

with the suspensory ligament and consequent lameness are due 

 to the encroachment — from one or both sides — of the bony deposit, 

 on the canal occupied by the suspensory ligament. This lateral 

 encroachment is shown in Fig. 82, which also exhibits a bony 

 deposit at the back of the upper part of the cannon bone, 

 apparently due to sprain of the suspensory ligament, which has 

 a portion of its upper attachment on that spot.

4:th. Two splints, one above the other, and oh the same side 

 of the leg. This classification is not general enough; for the 

 })ony growth may involve the entire splint bone; not only uniting 

 it for all its length to the cannon bone, but also increasing its 

 entire thickness as in Figs. 79 and 82.
