68 CALL FOR PUBLICATION Pr. P. Bourrelly died on October 31st, 1995 at the age of 85. He remained active a long time after he retires, and his books and papers on freshwater algae are well-known by authors concerned with freswater algae and protists. Also, he was the director of the journal Cryptogamie and we would like to render homage to him. It is a pleasure, therefore, to invite phycologists to contribute a dedicated paper to the journal, in 1998. Your contribution may either be an original research paper or, with the approval of the editor, a review paper. Contributions should not exceed 40 manuscript double- spaced pages excluding figures and tables. The deadline for the initial submission will be March 31st, 1997. All papers will be reviewed in accordance with journal policy and sent back for any necessary revisions. To ensure a 1998 publication date, revisions will have to be returned within one month of receipt. Please let me know (if possible by e-mail or fax) no later than May 31st, 1996 whether you will be able to contribute a paper or review. A title will be appreciated as soon as possible. Thank you.
