In discussing the etymology and history of, what we understand in the ordinary English of the meat industry, as "measles" in pork and beef, it is quite insufficient to consider the "bladderworm" stage of the parasite only, without discussing the historical advancement of knowledge regarding the adult tapeworm which succeeds the "bladderworm". The measle, bladderworm or larva, found
in the muscles of the pig, for example, and the adult resultant tapeworm of man are so closely related, that one cannot be successfully described or discussed, without investigation of the oorresponding stage in the other. It is obvious, however, that in an article on "Cysticercosis",
the bladderworm stage of the common parasite should receive the fuller consideration, although the adult, parent or final stage of the parasite must also receive attention, since we are merely dealing
with two stages of a parasite, usually passed in two different hosts, and in order to arrive at a plan of campaign towards eradication of the parasite at either stage, we should understand the histology,
pathological anatomy and peculiarities of both.
