y. There are besides two
diseases incidental to childhood, and one of them almost peculiar to it,
namely typhoid fever and measles, which are more apt than any others to
develop a tendency to consumption. During convalescence from either of
them, therefore, special care is needed.

In the grown person, consumption almost always attacks the lungs, and
this often to the exclusion of other organs. In the child, however, this
is not so, and though the lungs are indeed oftener affected than other
parts, yet in nearly half of the cases some one or other of the
digestive organs is likewise involved, and in about one in seven
instances the lungs are free and the digestive organs alone are
attacked.

Fever, cough, and wasting are the three sets of symptoms which in some
degree or other are always present in consumptive disease of the lungs.
The fever in the early stages of consumption is not in general severe;
but so long as the evening temperature of a child never exceeds 99 deg.,
there is no cause for anxiety. On the other hand, if the evening
temperature for a week or ten days together always amounts to 100 deg.,
there is grave presumption that consumptive disease is present. In
advanced consumption the evening temperature is constantly 103 deg. to 105 deg.,
while in the morning it may fall to 101 deg. or 100 deg..

Cough is but rarely absent even in cases where the lungs are but
slightly involved, for the irritation of the digestive organs often
excites a sympathetic cough, and in these circumstances observation of
the evening temperature will often furnish a clue to the right
interpretation of the symptoms.

There is a form of cough which is oftenest observed in children between
the ages of two and five years, which comes in fits closely resembling
those of hooping-cough, and each fit ends in a sort of imperfect 'hoop.'
This may depend on a particular form of consumption in which the _glands
connected with the lungs_ (the bronchial glands as they are called) _are
diseased_, and not the lung-substance itself. The enlarged glands press
on some of the nerves connected with the upper part of the windpipe, and
thus occasion the spasmodic cough. Always suspect this when a cough
persists for weeks together, not getting rapidly worse as hooping-cough
would do, but at the same time not growing better, as would be the case
with mild hooping-cough. The doctor on listening to the chest will solve
your doubts; the thermometer will h
