General Management of the Dog. 107 
is well known to every one; but the tick is not among 
the things: commonly presented to the eye, and we may 
therefore mention that it may be known by its spider-like 
shape, and by its close adhesion to the skin by means of 
“its legs, with which it digs into the surface. In size it 
varies from that of the head of a small pin to the mag- 
nitude of a small grain of wheat, but not being so long 
in proportion to its width. The colour changes with that 
of -the dog, and with the quantity of blood imbibed; 
-which always gives a greater or less tint of bluish red ; 
but in very young ticks the colour is a pearly grey. In 
~destroying fleas, the best remedy is the insect-destroying 
‘powder sold by Butler and M‘Culloch, of Covent-Garden, 
‘and by Keating, of St. Paul's Churchyard, which may be 
well rubbed in without fear of consequences. Lice and 
ticks require a stronger drug to destroy them, and this 
should be used with more care, as, being a mercurial pre- 
paration, it is liable to be absorbed if the skin is wetted, 
and then produces serious mischief, accompanied by sali- 
vation; or, if the dog is allowed to lick himself, this 
effect is still more likely to follow. The dog should 
therefore be kept carefully from all wet for at least twelve 
hours, and during the application of the remedy it should- 
either be carefully watched and prevented by the hand 
from licking itself, or it should be muzzled. The remedy 
is white precipitate, in-powder, well rubbed into the roots 
of the hair over the whole body, and left on for six hours; 
after which it should be brushed out. At the expiration of 
the week the application should be repeated, and possibly 
it may be required a third time; but this is seldom 
needed.
