Art. 1. — K. Fuji : 



From the values given in the above tables, the eurves No. 1 

 — No. 8 were reproduced on section papers in the same way as 

 in No. 37. These curves are shown in Plate VIII. In these 

 curves, ^u ^-i for several values of y were measured. Then the 

 îxiean of Vï^ for every curve was found and compared witli the 

 observed value of the modal latent period. Tlie unit of x and of 

 y are one division of the section paper. Using tlie mean of Vx-^r., 

 as the value of a-o, we calculated K.
