Measures to determine brightness of Comparison Stars for 93 and 94 Orionis. Near sigma Orionis
   This sequence is dependent upon that
selected for Wolf's variable "11,1904." The stars for the latter are designated by simple letters those for the variables 93 and 94 are accented and begin with h'

The fainter images on this plate are much too poor for comparison with the scale.

The main sequence is near Wolf's 11, 1904. The second sequence (accented) beginning with h' is near 93 and 94 Orionis.
