The historical discussion and the older bibliography are excel- 
lent. 
2. Bert, Paul.—Lecons sur la Physiologie Comparée de la 
Respiration. Paris, 1870. Excellent bibliography, historical 
summary and account of the subject in all classes of animals. 
3. Bernard, Claude.—Lecons sur les Phénomènes de la Vie 
communs aux Animaux et aux Végétaux. Tome ii, Paris, 
1879. A very suggestive and helpful work; it brings out with 
especial clearness the idea of the similarity of the underlying 
vital processes in animals and plants. 
4, Flint, Austin, Jr—The Physiology. of Man (five vol- 
umes), Vol. i, New York, 1868. Excellent historical summary. 
5. Zuntz, N.—Blutgase und respiratorischer Gaswechsel, in 
Hermann’s Handbuch der Physiologie. Band iv, Theil ii, 
Leipzig, 1882. Historical summary, some comparative phys- 
iology. ;

Amia, Lepidosteus, Acipenser and Polyodon. Proceedings of 
the Amer. Assoc. Adv. Sci., Vol. xxiv (1875), pp. 151-193. On 
pp. 151-153 are discussed the respiratory actions of Amia and 
Lepidosteus. 
7. Wilder, Burt G.—On the Respiration of Amia. Proc. 
Amer. Assoc. Adv. Sci., Vol. xxvi, (1877), pp. 306-313. 
Discusses fully the respiratory actions of Amia, and shows by 
analysis the changes that are produced in the air by its res- 
piration.
