They increased in numbers up to the twelfth day, when 11*6 % of the corpuscles contained them.
Calcareous corpuscles may also play a role in excystation because their numbers decline dramatically during the process.
The escape of small single parasites from corpuscles was never witnessed, and small parasites were never seen to divide.
The parasites did not rupture the corpuscle in the act of escaping.
Illustrating the behaviour of a large parasite within a corpuscle during the period 17 to 176 minutes after the blood was drawn.
They gradually increased in numbers so that roundly 1 % of the corpuscles were found infected on the tenth and eleventh days.
The assumption of material corpuscles did not go hand in hand with that of substance-specific entities.
The number of infected corpuscles as compared to uninfected ones was small.
