Summary. A description is given of the design of two atomisers for use in quantitative laboratory spraying for testing contact insecticides. Tables and graphs are given showing the weights of spray delivered by each form upon known areas placed in different positions inside the spray jars, and an examination is made of the change in the distribution of the spray with the progressive closure of the orifice and increase in the distance from the orifice of the surface sprayed.
