Lead poisoning

A = Polymorphonuclears.
  B = Lymphocytes.
  C = Large hyaline.
  D = Eosinophile.
  E = Transitional.
  F = Basophile.
  G = Microcytes.
  H = Megalocytes.
  I = Poikilocytes.
  J = Nucleated red.
  K = Plehn’s bodies.

  Corpuscles, Thoma-Zeiss.
  Hæmaglobin, Haldane’s instrument.
  Films, stained Leishman.

The form of lead inhaled is immaterial, and definite poisoning with
alteration in the blood may be occasioned, not only with white lead and
lead fume, but also even with lead sulphate and lead silicate.

The following table gives the result of blood-counts performed upon the
blood of persons employed in the manufacture of a paint erroneously
supposed to be innocuous, as the base consisted of lead sulphate and
oxysulphate:
