accustomed to it, and under these conditions thrush 
is almost certainly developed, so that few children 
escape an attack. It is not generally dangerous, yet 
it may, in some cases, compromise the health, and 
even cause the death of the child. In addition to care 
about cleanliness, a little pinch of bicarbonate of soda 
may be put in the feeding-bottle; this prevents the 
milk from turning sour. 
Onychomycosis.—This disease, which attacks the 
nails of men and the hoofs of uni-ungulates (the horse, 
the ass, and the mule), is caused by a parasitic fungus 
of the genus Achorion (A. keratophagus). In man it 
is termed dry caries, and it is a fungus which is readily 
transferred from man to the animals with which he 
has to do, just as Achorion Schenlenti of ringworm 
passes from man to the dog, cat, rat, horse, ox, and 
perhaps even to rabbits and gallinacez. 
In uni-ungulates the fungus is introduced into the 
cracked and superficial layer of the hoof through its 
fissures. In order to destroy it, this external layer 
must be removed, and for greater security an anti- 
parasitic treatment should be used. 
This remedy cannot be applied to the human subject 
without causing considerable pain; yet the nail may 
be pared and scraped, and the anti-parasitic remedy 
can then be applied.
