Contariloua 'Foot-rot in Sheep. 
isolated in pen No. 3, was healtliy, although the ground was 
extremely wet and the grass long ; the Welsh lamb also con- 
tinued healthy. 
At the end of October the mtei’est of the experiments was 
practically confined to the condition of- the Welsh ewe, which 
had been isolated since the commencement of the work, and to 
the two sheep from Denham. The Welsh ewe had been removed 
on October 4 to pen No. 2. This was a healthy pen, lying very 
low. By October 25 it was a “ quagmire.” On November 8 this 
sheep had sores at the interdigital spaces of all four feet, due to 
irritation by foreign matter (mud, hay-bents, Ac.), and was par- 
ticularly lame on the right fore foot, but not from foot-rot. On 
November 14 it had still sores on all four feet, and there was 
loss of hair on the coronets, heels, and legs as high up as the 
mud extended ; the interdigital spaces of all four feet still pre- 
sented sores. This condition might be described as “ foul in the 
foot ” or “ mud fever.” The sheep was turned into the seven-acre 
field with the other sheep on November 14. It did not up to 
the date of its slaughter on February 9 develop foot-rot. 
On November 8 the wether fi’om Denham had foot-rot very 
badly in the left hind foot ; the solar horn of both claws of this foot 
was “ separated,” and there was suppuration at the interdigital 
space. The right hind foot was nearly well. But the disease 
existed slightly in both front feet. 
On November 8 the Denham lamb had foot-rot very badly 
in the left hind foot. The right hind foot was better. It had 
also* foot-rot slightly in the right front foot. 
The Kentish lamb, which had suffered terribly from the 
disease, having had it in all four feet, had new claws growing 
down from the coronet of the outside digit of three of its feet. 
On November 14 both Denham sheep were greatly improved ; 
all the sheep were then in the seven-acre pasture, and improved 
in condition for about a month, some of them getting quite fat ; 
but on December 20 several of them again were extremely lame. 
This lameness appeared in a great measure to be due to the 
hardness of the ground, which was frozen, and to the overgrown 
and deformed condition of the feet. On January 11 (1892) the 
Denham lamb, which was very lame and lay about a good deal, 
was killed, and the feet retained as specimens. No sign of 
foot-rot was found on examination. On January 20 the feet of 
the speckled-faced teg and of the Kentish lamb were found 
to be deformed, but were free from foot-rot. 
On February 9 the remaining sheep were killed. All were 
free from foot-rot. 
A fourth series of experiments was carried on at the same
