Since 0 = the loss will (^90) =: subtracting this from we have 116 INJUEY, RECOVERY, AND DEATH Recovery after exposure to CaCL may be calculated inprecisely the same manner as recovery after exposureto NaCl. The only dit^erence is that in formulas (2), (3),(5), (8) and (9) we must employ for the velocity con-stants {K^, Kq, Kj^, K^y K^ and Kj^j) the values givenfor CaCls in Table V, page 98. In formulas (6) and(7) the values of the velocity constants are always thesame (Z^ = and ^3^=) since these are thevalues which are normal for sea water. _o-%, o Ca CI2D Sea Water. 400 MINUTES 800 Fig. 45.—Curves showinR tho net elertrical resistance of Laminaria anartlhii in CaCh and in sea water.
