OXYGEN CONSUMPTION IN GOLDFISH 69 RESULTS (a) Relation of temperature to standard metabolism The relation of the standard metabolism of the goldfish to temperature has been investigated by other workers on a number of occasions. On two occasions in particular (Ege and Krogh, 1914; Gardner, King and Powers, 1922) this relation has been worked out over a considerable range of temperature.

The relation of temperature to standard metabolism in the goldfish. rates of oxygen uptake are used in this figure rather than the actual values so that a comparison can be made between the relative rates of change. The relative rates of change with increase in temperature are very similar in the three sets of data. Since different techniques were used in the three cases, such agreement can probably be taken as a satisfactory indication that the relative change is a stable characteristic of the species, although it must be remembered that this particular curve is char- acteristic of quite a number of other animals also (Krogh, 1941). There does not appear to be any indication of any difference in this relative rate with difference in size such as wells (1935) believed was the case in Fundulus parvi- pinnis. However, his evidence is somewhat confused by the fact that the rates at different temperatures were measured at different times of day. Moreover, a good deal of the divergence in the rate-temperature curves he gives is an attribute of the magnitude of the absolute rates and disappears if a semi-logarithmic plot is used, as in Figure 2. The rate of oxygen uptake per unit weight does not bear any consistent relation with size in the three sets of data
