STUDIES ON THE VARIABLES OF THE ALGOL-TYPE. lo 



45. Symmetrical light-curve of a flat minimum extending over three 



hours near!}'. 



46. Nijland observed a secondary minimum of the magnitude lO'^.ß but 



he noted that it ought to be confirmed by tlie further observations. 



47. Symmetrical. 



48. The increase of light is much faster than the decrease. 



51. A marked difference between both branches of the light-curve, the 

 increase much faster than the other. Nijland observed it to be 

 symmetrical. 



53. The light-curve consists from two symmetrical branches gently 

 curved. 



55-56. Same as the above. 



57. Two kinds of minima appears on the star, the principal sinks till 



9"*.6 and the other to 9"M, both lasting over a half day. 



58. Symmetrical light-curve. 



59. Symmetrical light-curve of a flat minimum lasting 0.2 day. 



60. Symmetrical curve tending to that of the short period variables. 



61. Symmetrical. 



62. The light-curve is of the type of S Cancri ; a marked difference 



being noticed between both branches. The rise, being faster. 



63. Observations showed some difference between each minimum. 



But the light-curve is symmetrical. 



64. Symmetrical. 

 67. Symmetrical. 



70. Symmetrical, tending to the class of the short period variables. 

 72. Same as the above. 

 74. Symmetrical, 



77. A secondary minimum of the range 0"\3 takes place IT'.Oö after 

 the principal minimum, 



80. Principal and secondary both appear. 



Princ. 8'\8-9"\8, in range and lasts 0''.6 



Secon. 8^8-9^3 in range and lasts 0'^6. 



The curve is nearly symmetrical. 



81. Symmetrical, showing a flat minimum lasting 0.2 day. 



87. Unsymmetrical, the decrease of light being faster than the increase. 



The ascending branch accompanies secondary unduration. 

 91. Uniform decrease and increase of liçjht with a flat minimum lastino; 



an hour.
