No particular search was made for such lesions until the epidemic was nearly half over. At that time word was received from Camp Devens that hemorrhagic lesions in the rectus muscle were being found. Thereafter, the recti were examined with care.

Abscesses supervening upon the rectus hemorrhages are reported by Beals, Blanton and Eisendrath (7), and by Glaus and Fritzsche (47). Generalized abscesses are reported by the latter and by Dietrich (34). Abrahams, Hallows and French (2) report subcutaneous abscesses; Beals, Blanton and Eisendrath, abscesses of the kidneys.

The sinuses of the head and middle ears were examined in a number of cases with negative findings. Suppuration of these areas is, however, reported by others.

Stone and Swift (138) found pus in the sphenoidal sinus in 68 per cent of their cases with pneumococci, streptococci and B. influenzæ present. Wolbach (162) found twenty cases of infection of the sphenoid sinus from twelve of which B. influenzæ alone or combined with pneumococci or streptococci were isolated. Lacy (74) reports four cases of influenzal sinusitis.

Acute nephritis has been reported by many observers, but the histological descriptions have been so meager that judgment regarding it must be suspended.

This condition has been met with more frequently in other localities. Stone and Swift (138) report it in a high percentage of their cases. Lamb and Brannin (77) encountered it seven times, and Blanton and Irons (12) report two cases. Borst (15) and Jaffé (66) also have found this complication.

Cheesman and Meltzer (24) demonstrated as early as 1898 the importance of primary injury for the localization and development of secondary infecting bacteria.
