Toxins for the eradication of flour beetles

Description

These data are from an experiment, reported by Gilliatt (1948), on vasoconstriction of fingers after a single deep breath. The measurement process was not sufficiently precise to determine the degree of vasoconstriction, simply its presence or absence. Interest lay in how the presence of vasoconstriction relates to the volume and flow rate of air during the intake of breath.

Details

Finney (1947) reported the data and discussed a variety of models in some depth. Note that the table of data in this paper seems to contain a misprint, with observation 32 showing a rate of 0.03 while the plots indicate this to be 0.30. This dataframe incorporates this correction.
