that be lias bestowed tlie closest attention, and his final monograph 

 upon the subject, -which, dropping the term Bhetic, he has entitled " Die 

 fossile Flora der Grenzschichteu des Keupers und Lias Frailkens," is a 

 very valuable contribution to paleobotany. Still later (1868), he took 

 up the Muschelkalk beds of Recoaro, first noticed by Catullo,^" but 

 treated by a number of authors, and produced a finely illustrated little 

 work " Ueber die Piianzenreste des Muschelkalkes von Eecoaro." Be- 

 sides his "Beitragezur Flora der Vorwelt" in the Palceontographica^ 

 and numerous minor contributions, Dr. Schenk has elaborated the fossil 

 plants for Baron Richthofen's "China,'"'' and, since Schimper's death,, 

 has gone on with the vegetable department of Zittel's " Handbuch der 

 Palaontologie.'"^ 



21. Saporta. — The death of Professor Heer broke up the illustrious 

 trio of continental palepbotanists who had so long taken the lead in the 

 study of the fossil plants of the Tertiary formation — Heer, Ettings- 

 hausen, and Saporta. The two that remain are of more nearly the same- 

 age, and in many respects admit of a more ready comparison; still their 

 fields of labor are so well separated that no conflict can occur in their 

 operations, and both seem likely to continue uninterrupted for many- 

 years their already extensive investigations. 



The Marquis (until a year ago Count) Gaston de Saporta, was bora 

 in the year 1823 at Saint Zacharie, department of Var, in Provence, 

 France, and it was in the near vicinity of his native place that he first 

 begau'^ his paleobotanical studies, and to the thorough illustration of 

 the fossil botany of Provence he has always devoted his best energies. 

 His "Etudes sur la v6g6tation du sud-est de la France 4 l'6poque terti- 

 aire,"" begun in 1863, has thus far remained his chff d'cetivre, and most 

 of the localities treated in this work are situated in Provence. In 1873 

 he published "La revision de la flore fossile des gypses d'Aix," which 

 was practically a revision of the "Etudes."" Among his other more 

 important works on Cenozoic floras may be mentioned his "Prodrome 

 d'une flore fossile des travertins de S6zanne,"^^ in which the flora of the 

 Eocene, or Paleocene, as he terms it, is better set forth than in any other 

 work, and his "Essai sur l'6tat de la v6g6tation a I'epoque des marnes-
