This can be seen on reference to the Charts 7 and 8 (Experi-ments 7 and 21 respectively). The animals used in all cases weremedium sized rabbits, from about 1600 to 2400 gms. weight (except inone case, Rabbit 50, Experiment 64) and the temperature was alwaystaken at intervals for an hour or more before the injection was many cases the respiration rate was observed, but no observationswere made on the actual amount of ventilation.

This was determined indirectly by measuring the CO2 productionand given off, and calculating the oxygen used. A modification 184 Expertnxntdl Stmlji of Fever of the Respiration Apparatus described by lialdane (1892) was em-ployed. Instead of using the large glass bottle which Haldanerecommends, a metal box (Fig. 1) was used. Its dimensions were40 X 20 X 20 cm., and it had a false bottom of wire gauze, on whichthe animal rented.
