Chick eggs were injected with 0.1 ml of 2% Malathion in corn oil on the 5th day of incubation, and its effect on skeletogenesis, particularly the development of the tibiotarsus, was studied throughout the incubation period.
Le cinquième jour de l'incubation, on a injecté, dans des oeufs de poulet, 0.1 ml d'huile de maïs contenant 2% de Malathion, afin d'étudier l'effet de ce traitement sur le développement du squelette, plus particulièrement de l'os tibio-tarsal, durant l'embryogenèse.
