DISEASES OF THE EAK. 363 Ocular symptoms.—Aside from strabismus in one case, and a differencein the size of the pupils in another,—both of which conditions did not man-ifest themselves until toward the end of the disease,—I have not observedany ocular symptoms in either the acute or the chronic varieties of mastoiddisease. In the more severe cases, the patients are very apt to complain ofpains that shoot into the eye of the side affected, and in one or two of thesecases I have observed a slight conjunctival Redness, swelling and prolapse of the upper and posterior cutaneous ivallof the osseous portion of the auditory canal.—In acute inflammation of theantrum the seventy of the attack may be measured quite accurately by thecharacter and extent of the changes which take place in the posterior and.

If a horizontal orslightly inclined section be made in such a mariner as to pass through thisportion of the auditory canal and also through the antrum—as has beendone in the accompanying cut taken from Henles Anatomy —the proxim-ity of this cavity to the upper and posterior limits of the osseous auditorycanal will be appreciated at a glance. In cases of chronic purulent inflam-mation of the middle ear the mass of bone lying between these two cavi-ties may assume such an ivory-like hardness that no inflammatory influencescan traverse it.
