Abstract
DURING experiments on the oxygen consumption of Blatella germanica, it was observed that one specimen which was used on the day of its last moult, when it was still pale in colour, had a respiratory rate about 50 per cent higher than the normal. Experiments were accordingly undertaken in which the rate of oxygen consumption of the last stage nymphs of a related species (Blatta orientalis) was measured at intervals until after the animals had moulted and become adult. The Barcroft apparatus was used at 25° C.1
