Relation of Afferent Impulses to Vasomotor Centres. 283 placing of the points which it connects, it is desirable to inquire whether the number of observations fix- ing each point was large enough to permit acci- dental errors to be com- pensated. It may at once be said that the number of observations in this in- vestigation, though fairly large for the usual research, is regrettably small for statistical purposes. In- deed, one reason for pub- lishing these results at this time is to urge the collection of such data by many investigators. Nevertheless, the present results appear to be sub- stantially accurate. The following illustration will be of interest. In the experiments of January 21, January 30, February 2, and February 9, the depres- sor nerve was stimulated eighty times with induc- tion currents of a strength between 400 and 799 Kro- necker units. The average absolute fall in the blood pressure was 24 mm. Hg, around which central value the individual observa- tions were symmetrically grouped.
