The minus (—) sign is due to the fact that while the positive (+) 
direction is along the axis z outward, the temperature and 
thermal gradients decrease in this direction; a positive (+) 
sign would indicate an inversion of temperatures and thermal 
quantities outward. In the case of p, k, the coefficients are all 
positive; in the case of p l , k 1 they are generally positive in the 
lower levels, but sometimes (+) and sometimes ( —) occur 
in the upper levels. Since the original observations of the 
velocity are lacking, those used being supplied by analogy, it is 
probable that the data of Huron, September 1, 1910, are inade 
quate to produce accurate values of p l , k l .

It was supposed that this was due to the fact that the velocities
