The Petri dish containing the culture is inverted over this and sealed with plasticine. McLeod's Method. This method requires a porcelain dish con- sisting of two separate chambers for containing the pyrogallic acid and potassium hydroxide. The special Petri dish has its free edge turned inward and upward. Around the upper cover of the porcelain dish is a groove to contain plasticine which prevents the ingress of air. About 7 of a 10 to 20 per cent pyrogaUic acid is run into the chamber marked A in Fig. 18. Into part B are put 7 of a 10 per cent potas- sium hydroxide. The Petri dish is then pressed down into the plas-.
