Measles may also present certain irregularities in its various stages without necessarily departing from the otherwise benign character of the disease. As stated elsewhere, it is believed by some writers that a greater part of the period of incubation is occupied by symptoms which already indicate the activity of the measles poison in the system, and that, therefore, this stadium in reality lasts but a few days. This opinion does not seem to be generally accepted; at any rate, I think we are quite safe in saying that in the majority of cases no departure from the usual latency is observed. The deviations in the stage of invasion have been considered above, and mostly concern its duration and the character of the temperature. Evanescent rashes, which have nothing in common with the specific exanthem, are sometimes observed at this period. The eruption of measles may present certain peculiarities. First, as to localization. Instead of coming out on the face first, it may primarily develop on other parts of the body, provoked into existence, as it were, by local exciting causes; thus, where ointments or plasters have been applied or upon a part subjected to constant pressure. It may affect only one-half of the body, or entirely spare paralyzed extremities (Mayr). In some instances the papules are so sparse, indistinct, and short-lived as to be scarcely appreciable. Second, as to the physical characters of the eruption. Hebra and Mayr recognize the following modifications: Morbilli laevis. The efflorescence is smooth and flat, and the individual lesions are separated from each other by normal integument. This is the common form of measles. p. 570 Morbilli papulosi.
