was appointed Harrison Fellow in Botany in 1899. The 

 above subject was outlined and assigned to him, along the 

 lines as now being published, by the Professor of Botany, the 

 entire study being intended as an original investigation and 

 thesis. From the abundant facilities furnished by the Uni- 

 versity Garden and the Dreer collection of water lilies, the 

 subject grew in importance, so that the author felt warranted 

 in presenting the taxonomic part alone as a thesis for the 

 Ph. D. degree. He was then awarded the Harrison Senior 

 Fellowship in Botany for two years, and owing to the ample 

 leisure that this afforded he was enabled to complete the 

 original study in its entirety. This was presented to the 

 Carnegie Institution by the writer and was duly accepted for 

 publication. Through the interest of Dr. S. Weir Mitchell, 

 and on permission from Provost Harrison, Dr. Conard then 

 spent some time in visiting the European herbaria on the 

 Carnegie foundation. He thus secured additional informa- 

 tion, which has been incorporated in the work that will 

 shortly appear. 



The second of the above monographs is in preparation, and 

 will embody the results of study in the field, the laboratory, 

 the herbarium and the library of the past twenty years. 

 Through action of the Provost and Trustees of the Uni- 

 versity the writer was able to devote considerable time dur- 

 ing the past spring and summer to investigation of the group 

 of the Ascidiaceae in European institutions. The work will 

 incorporate these results, and will, it is expected, be published 

 as a University Contribution. 



Mr. Louis Krautter's investigation is now in progress and 

 will include a historical, morphological, physiological, taxo- 

 nomic and ecological study of the above suggestive genus of 

 North American plants.
