Perhaps it is because of our general disregard of its importance as a disease that so little work has been done on the morphology of the blood in epidemic parotitis. From such a viewpoint it is true that a perfect knowledge of the pathological physiology of the disease is of comparative little import. But this disease, it has been observed, is accompanied by a lymphocytosis, and the problem of lymphocytosis is an interesting and important one. The blood-picture of this disease is also of distinct value in differential diagnosis.
A perusal of the literature on the blood-picture in this disease shows it to be very fragmentary; so that there is need for summarizing and a proper correlation of the results obtained by the various observers.
Since the work of Wile,1 I have been unable to find any noteworthy contributions. Wile's bibliography refers to the work of Cabot,2 who
