Diseases of the Skin. 237 
glands, whose especial office is the production of the 
secretion commonly known as sweat. Physical condi- 
tions gave the denial to this theory, as it became evident 
under certain forms of disease in which the functions of 
the kidneys were suspended, that the skin vigorously 
eliminated in an aeriform state the effete products which 
imperilled the animal’s existence. The progress of his- 
tology, or the study of the ultimate tissues of the animal 
body, has decided the existence of sudoriparous glands in 
the skin of canine animals, which assume an activity of 
secretion proportionate to muscular exertion. Neverthe- 
less, the office mainly consists of sending forth the waste 
and useless products of decomposition in the form of 
exhalation or vapour, any appreciable moisture being 
probably the after-result of ,cooling and condensation. 
As we recognise the existence of these organs, we look 
in other directions for the causes which secure the genesis 
of maladies formerly attributed to their absence. The 
skin of the dog requires especial care. It is liable to 
various forms of disease which owe their origin entirely 
to the absence of proper regimen and sanitary excellence. 
Deficiency of air, exercise, or food, as well as excess of 
the latter, and especially when unsuitable, work out their 
resuits in disaster and peril to general health. JZs- 
management of this kind is the sure road to the end 
alluded to, general foulness of the skin being a significant 
danger-signal. Immediately it is observed the proprietor 
should resort to a thorough cleansing by water and 
‘“‘ Sanitas ” Dog Soap, using warm water in winter, and on 
all occasions taking especial care to remove moisture 
from the skin as much as possible by friction with dry 
cloths, and with protection. from cold draughts. Con- 
jointly a vegetable diet should be substituted, along with 
regular exercise. Spratt’s Beetroot cakes admirably come 
to the relief of the owner under these circumstances, often 
saving the lives of useful servants when they are being 
ignorantly killed with kindness. , 
Alopecia, Baldness, or Loss of Hair, may be partial or 
complete, sometimes being confined to a few or single 
patches on various parts of the head, body or legs, or it
