5) The algae of the lake were foimd iu the same region as the 

 Crustacea and with amounts in the different levels roughly corresponding 

 to the number of Crustacea. They were chiefly species of Lynybya, 

 Anaboena, and allied forms. No attempt was made to estimate exactly 

 their distribution. 



6) No species of Bosmina or Ceriodaphnia has been found in the 

 pelagic fauna of the lake. Leptodora was not collected in numbers 

 sufficient to determine its distribution. 



7) These results are quite different from those announced by France 

 in the Biologisches Centralblatt for Jan. 15, 1894. The study 

 was undertaken with the purpose of testing his results in a body of 

 water about twice as deep as lake Balaton, and with the expectation 

 that they would be in general confirmed. The study of the Crustacea 

 has been continued to the present time (Jan. 1895) with results exactly 

 agreeing with those of the summer. During the late fall and winter 

 no night observations have been made but the upper part of the water 

 has always contained its full proportion of Crustacea by day. 



8) The results of this study will appear in full in the forthcoming 

 10th volume of the Transactions of the Wisconsin Academy of Sciences, 

 Arts, and Letters.
