Contagious Foot-rot in Sheep.

and the foot examined, when it was observed that the skin of 
the interdigital space was much inflamed, and that suppuration 
existed at the upper border of both claws at the interdigital 
space, whilst the leg immediately above the hoof was swollen and 
very hot. The left hind foot of this sheep was very hot, and on 
June 4 the disease had developed in this foot also. 
On June 3 one of the tegs in pen No. 1 showed unmistakable 
symptoms of foot-rot in its right hind foot, but lameness was 
not marked until the next day ; on this date also another of the 
tegs became lame. The remaining teg in this pen did not be- 
come affected until two months later, namely on August 2, when 
the pasture was again very wet. Two of these experimentally 
affected sheep had the disease in three of their feet, whilst in one 
it appeared in one foot only. During all this period of time the 
four sheep which had meanwhile been kept in pens Nos. 2 and 
3, under precisely similar conditions as the sheep in pen No. 1, 
except that they had not been in contact with affected animals, 
continued sound. 
One of the Kent ewes and the Welsh ewe in pen No. 1 
lambed in May, each having one lamb, sound and well nourished. 
On August 8 the Kentish lamb which remained from its birth 
in the pen had foot-rot in the off fore foot, and by August 16 all 
the feet were attacked. 
On August 31 the sheep from pen No. 1 were placed on 
another pasture (seven acres) ; and on September 2 the two 
sound tegs from No. 2 pen, and a Welsh ewe from No. 3 pen 
(also sound), were put into No. 1 pen, from which the affected 
animals had been removed two (lays previously. On September 
13 this Welsh ewe had foot-rot in both her front feet ; on 
September 19 one of the tegs had also become affected. On 
September 19 a Cotswold wether and a cross-bred lamb (both 
sound) were sent from Denham, and were placed in the seven- 
acre pasture with the eight sheep out of pen No. 1. On Sep- 
tember 23 all the sheep were placed in this pasture with the 
exception of one Welsh ewe, which had never been removed 
from pen No. 3, and was still sound. On October 2 the 
remaining teg ^ became affected in her right hind foot. On 
October 9 the cross-bred lamb from Denham had foot-rot in her 
off hind foot, and on October 1 1 the Cotswold wether had the 
disease, and Avas very lame in his right fore foot ; while on 
October 18 both of the Denham sheep had the disease in two 
of their feet.
