The disease is apt to assume the chronic form when 
the ordinary substance of the gland becomes indurated,

When the enlargement is considerable the weighty parts 
may be suspended in a bandage passed round the back.

varies with climate and other conditions, as health, &c. 
Spring and autumn ‘are the seasons in which it is seen in

the ugliest curs, and if allowed full liberty, her progeny will, 
as a natural consequence, be a mixture of breeds. The
