[Changes in the leukocyte formula of healthy people according to age and sex in the Province of Forli].

On the ground of a statistical elaboration which has been carried throughout the Province of Forlì examining healthy people in order to observe eventual alteration in leucocytes' formula according to age and sex, in this way after a classification into five ageclasses, between 20 and 70 years, 250 men and 250 women, we could affirm that leucocytes' formula changes remarkably considering age and sex. So why we cannot take into consideration just a unique leucocytes' formula but on the contrary it is necessary to relate the above said formula to the age and the sex of a subject.
