De l'influence de deux ordres de berfs qui déterminant les variations de couleur du sang veineux dans les organes glandulaires. (+) Sur la quantité d'oxygène que contient le sang veineux des organes glandulaires, à l'état de fonction et à l'état de repos; et sur l'emploi de l'oxyde de carbone pour déterminer les proportions d'oxygène du sang. (2 Papers).

Paris, Mallet-Bachelier, 1858. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome 47, No 6 a. No 10. Pp. (245-) 279 a. pp. (393-) 431 (entire issues offered). Bernard's papers: pp. (245-) 253 a. pp. (393) -400.

First appearance of these landmark papers in which Barnard explains his discovery of how the nerves controls the blood vessels. This is the "discovery of the vascoconstrictor and vasodilator nerves and description of their function of regulating the blood supply to the different parts of the body."(Garrison & Morton, No. 774).

"In 1858 (the papers offered) Bernard demonstrated the existence of vasodilator nerves by finding an increased blood flow through the submaxillary gland, when the corda tympani is stimulated. He also observed that the venous blood became bright red. Since that time an enormous amount of research has been carried out on the vasomotor system."(R.J.S. Mcdowall).
