    the vessels which run from the upper wall of the mea- tus on to the drum-membrane, above and behind the short process of the hammer. When the position and external surface of the drum-membrane more nearly approach the condition usual in adults, as in older children, inspection gives more certain appearances. If the patient is seen in the very beginning of the disease, in addition to the coarse injection of the external vessels of the hammer and the usual intense redness of the neighboring parts of the osse- ous meatus, there is a sjig^tc^iijr^ö^marked redness over the whole drum-mejrfs5£ane, due iCT^^wk hyperasmia of its inner mucous layei^T else^r^'ffie'oppo^wSie labyrinth wall. As exudation occilrs, tftiA£^]fclra}$Q5is gradually changed; the drum-membraVe^s the result of serous infiltration, loses its translucenVy'^wi .exteoiafcJgU^tening, so that it appears dull-gray witnNom recT^j&gsels. As the loosen- ing of the external epidermal surface increases, the manu- brium of the hammer, heretofore visible as a yellowish line in the middle of the membrane, becomes indistinct, and finally its position is only recognized by a reddish line of vessels accompanied sometimes by irregular ecchymoses- That an abundant secretion is present in the tympanum is in children made apparent most commonly in the posterior upper quadrant of the drum-membrane which bulges out as a yellowish or gray prominence easily recognized even by the inexperienced ; in addition to this, just as in adults, single large radiating vessels are seen in the lower half of the membrane, the remainder of the membrane being very much drawn inwards. For making out all of these condi- tions, a plain hand-mirror, such as is to be found in nearly every house, is sufficient; with this, sun or lamp light can be thrown into the ear. Not infrequently, swelling of the lymph-glands is found, not only on the side of the neck when they are dependent upon inflammations of the nose and throat, but also directly behind the auricle where one or more of them always ex-
