Note.— In the preliminary work one observation at 9 p. m., October 3, and four observations at 6, 7, 8, and 9 a. m., 
October 10, were used with the above. As this was a period of considerable abnormal change, the effect of taking such 
partial observations into the mean was to give an erroneous curve for the diurnal oscillation. The following table gives 
a scale of corrections applicable to observations made at Albuquerque, N. M. It is to be regretted that the mistake was 
not discovered in season to allow the original observations to be properly corrected ; but the resulting errors are generally 
small.
