176 The Management and Diseases of the Dog. 
When matter has formed, and is approaching the surface, 
the sooner it is evacuted the better, otherwise sinuses are 
liable to form, and render the case tedious and difficult. 
For subsequent treatment see “ Abscess.” 
Chronic mammitis is denoted cy an indurated and 
enlarged condition of the gland, and may be the result of 
lingering subacute inflammation, or proceed trom the acute 
form. It is attended with but little pain or constitutional 
disturbance ; but, unless early measures are taken for its 
removal, it becomes a permanent induration, and may 
ultimately, if excited, assume a cancerous condition. 
Treatment—The daily application of iodine ointment, 
or the tincture, to the affected part, and the iodide of 
potassium in one or two scruples daily, are the most 
effectual agents in this complaint ; repeated friction with | 
the hand is also of service, and where the enlargement is 
considerable and weighty, it may be conveniently, and with 
benefit, suspended by means of a handkerchief tied over 
the back, or a net made for the purpose and fastened in the 
same way with tapes.

LACTEAL TUMOURS. 
The milk ducts are liable to become obstructed when not 
sufficiently drained of their contents, or from some mal- 
formation. Any such obstruction to the outflow of milkis 
calculated to produce much mischief. - Lacteal tumours, 
perhaps the least hurtful that can arise, are thus frequently 
caused. 
Symptoms.—The mammary gland affected is knotty ; the 
irregularities being even, movable, and painless : in the 
early stage these bodies have a fluctuating feel, which 
disappears as their period of existence lengthens. 
Inflammatory action may be excited in them by injury, 
and suppuration result.
