such disease in or upon any forest, chase, wood, moor, marsh, 
heath, common, waste land, open field, roadside, or other 
undivided or unenclosed land, shall on conviction of any 
such offence forfeit and pay a sum not exceeding twenty 
pounds.’* 
This measure was added as an additional clause to an 
already existing act u to extend and continue the act to pre- 
vent the spreading of contagious and infectious diseases 
among sheep, cattle, and other animals,” the provisions of 
which for the recovery of the penalties were made to apply to 
the disease in question. We believe that the sheep and 
cattle contagious disease act applies only to England, and as 
such Scotland and Ireland are without legislation with regard 
to the sale of glandered horses; an anomaly which should 
not continue, and one: which we hope to see removed when 
Parliament again assembles for the despatch of business. 
EARLY DEVELOPMENT OE TEETH. 
At the Salisbury meeting of the Royal Agricultural Society,, 
a short-horn bull, whose age, calculated down to the day of 
the show, according to the certificate of the breeder and 
owner was two years eight months and a fortnight , was found; 
on examination to have put up the whole of his permanent 
incisor teeth, the corner ones having very recently cut the 
gum. We deemed this a fitting case for inquiry, and on 
investigation we were perfectly satisfied with the evidence 1 , 
adduced by the breeder of the correctness of the certificate. 
This case we believe to be an extraordinary exception to 
the rules applicable to the dentition of the ox, and to be 
the earliest recorded instance of the cutting of the whole of 
the permanent incisors, and as such it is most valuable in 
assisting the veterinary surgeon in arriving at a decision in; 
disputed cases of age. We have only met with about ten or 
twelve cases in the examination of some fourteen or fifteen 
hundred animals of equal purity of breed as this one, and as 
well fed and managed, in which the permanent incisors were 
cut by the time the animal was two years and ten months 
old. Here, however, we have an instance in which they are 
all in the mouth six weeks before that time.
