A propos des algues fossiles.

Paris, G. Masson, 1882. Folio (37.0 x 28.1 cm), [ii], 82 pp.; ten tinted lithographed plates by Leuba, several text engravings. Original printed paper cover over limp boards. = A very rare and well-produced publication on fossil algae, with fine illustrations and descriptions of new and poorly known species. This copy is one of 15 on Dutch paper, being no. 15. "In his work in general Saporta, French paleobotanist (1823-1896), was a patient and meticulous researcher who attempted both to give a precise description of a species and to relate it to historical developments so as to clarify its origin. He emphasized the difficulty of determining species and advised caution; while he has been accused of erroneously increasing the number of species, such accusations are unjustified, and recent studies have frequently served to confirm his general views. Saporta's scientific reputation was widespread." (DSB XII pp. 104-105.) Uncut. Wrappers chipped at edges, some minimal foxing, and in all, a very good copy. Nissen BBI, 1723.
