The constants obtained in this way are listed below:

Assuming = 1 for January, and using the same origin for 

 determining the time in the expression for wind velocities, the expres- 

 sion for the temperature becomes

remembering that C = 8.3 and D = 5.6 (p. 376). 



The value of p 2 = 7760, when expressed in c. g. s. units is

which is about 25,000 times the laboratory value (Wegemann, 1905a, 

 p. 139). But this quantity /* 2 is the same as the Mischungsintensitat 

 (Jacobsen, 1913, p. 71), which is a measure of the rate of transfer of 

 salts, heat, or other properties of sea water arising from the mixing 

 of water particles in the alternating circulation (p. 368). Suppose the 

 diffusion of salts and the molecular conductivity of heat to be negligible 

 in comparison to the rate of transfer due to the alternating or 

 reciprocal changes in the positions of the water particles: then as 

 Jacobsen (1913, p. 71) says, the value of this coefficient, the Mischungs- 

 intensitat, determined from any of the properties should be the same 

 under the same conditions. He found values ranging from 1.9 to 3.8 

 from observations on currents and the distribution of salinities in the 

 sea near Denmark. From observations on tidal currents and salinities 

 in a neighboring region he obtained the values ranging from 0.3 to 

 11.4. The value 30 obtained from temperatures in the San Diego 

 region is of the some order of magnitude, but the intensity of the 

 circulation in the two regions would probably be different, hence the 

 coefficients would be expected to differ. 



The idea regarding the alternating motion of water in the ocean 

 held by Kriimmel and Ruppin (1905, p. 36) may be summarized as 

 follows : The coefficient of viscosity determined from laboratory experi- 

 ments, in which the motion of the water is slow and takes place along
