should rather expect them to be transmitted more or less regularly, 

 but they appear for one or a few generations and then disappear 

 without any particular regularity or definite sequence. This behavior

 conditions under which the cultures were grown were made as uni- 

 form as practicable in order to eliminate the influence of different 

 factors of environment.
