Neuchatel. — Observations are apparently made daily of the sur- 
face water, but seem not to be published in detail. Resumes may be found 
in the Bulletin Soc. Sci. nat. de Neuchatel as follows: for 1856, in Vol. 
IV, pp. 250, 252; for 1857, iv, p. 429; for 1858, V, p. 141; for 1859, v, pp, 
310, 311; for 1860, v, p. 752; for 1861, vi, p. 247. The publication of 
the resume seems to be interrupted after 1861. [Observations inter- 
rupted?] Prof. Hirsch announced in Yol. x, p. 29, that daily obser- 
vations of the temperature of the water had been made since January 1, 
1874.

[The observations on the Starnbergersee were made June 23, 1866. The temper- 
ature at the bottom (406 Bav. ft. = 118.5 meters) was 3°. 45 C., which experiment 
showed it to be the temperature of greatest density of the water at the bottom. The ob- 
servations on the Chiemsee were made September 17, 1866. The bottom tempera- 
ture (273 Bav. ft. = 79.8 meters) was 7°.l C.]
