Hence the largest deviation of 0.'5 is reached after the 
time of maximum obscuration. 
Horizontal Intensity. 
The H-curve seems to have suffered a slight increase at 
3^p, followed by an equally small decrease, but the wave 
is so shallow, that the unavoidable errors of a pencil calque 
make any conclusion too uncertain. 
Vertical Intensity. 
The Z-curve exhibits no minor waves at all. 
Manila. 
Minimum distance of central line + 5° NW. Time of 
maximum obscuration + 3^ 0" p. 
The normal hourly values have been calculated, after 
omitting disturbed days, with the aid of the hourly readings 
at the following dates: March 1, 2, 8, 9, 10, 13, 15, 16, 18, 
19, 20, 22, 23, 25, 30, 31. 
Departures from the daily mean. 
For D the residuals show an irregularity at 3^ p, which, 
however, is not to be observed in the pencil calque received.
