64. R Leonis Minoeis. — The maxima, according to Schiinfeld, are 

 subject to irregularities up to 12 days. Increase of light much 

 quicker than decrease. Increase from 9 m. lasts from 40 to 80 

 days. 



65. H Leonis. — This remarkable variable lies closely south of 19 

 Leonis, with which it has been sometimes confused, The period 

 given in the Catalogue was calculated by Schonfeld from observations 

 since 1818 ; and the Elements show irregularities, but no general 

 lengthening or shortening of the period since the time of Bradley and 

 T. Mayer. The minima are also affected with similar irregularities. 

 The star is closely preceded by two stars about 8 m., which form, 

 with the variable, an isosceles triangle. The star is considered by 

 most observers to be very red. I found it about 7|- m., and fiery red, 

 Pebruary 9, 1877, with 3-inch refractor.
