Blair*** has taken the two points from Boche's data, inserted
these into his (Blair's) equation relating reparable and irreparable
damspe,

in the proper range."
However, the constants of his equation hsve
checked well vith more extensive data on other animals,
His cquations
Arifcerve that the rate of racovery of repo able antury is fastest in
ne mouse (ef

gn the rut and atec.b cne-seventh as fast in the ginea pig soc dog,
but as Llcir pointed cut, the reaction cf the dog is more repvesentative of the larger, longer-lived aninals.
