Summary
The values of the final maximal intra-arterial blood pressure and the average frequency of cardiac contractions were studied in 4 dogs which lay at rest. In experiments of up to 50 minutes there occurred a gradual reduction of these values depending on the duration of the rest period. This regularity was observed both in dogs intact and in animals whose vessels were not subject to the cerebral neural tonic effect at the site of examination.
