1. J. Bertrand Thermodynamique. Paris, 1887.
2. J. Bertrand Calcul des probabilités. Paris, 1888 (see § 1.2). Second ed., 1907. For all practical purposes, it differs from the first one only in that the page numbers do not coincide. Reprints: New York, 1970 and 1972. I did not see the second of these; the first one is a reproduction of the first edition, a fact which is not stated in the publisher's evasive annotation.
3. J. Bertrand D'Alembert. Paris, 1889.
4. J. Bertrand Pascal. Paris, 1891.
