and the lowest temperature, 46°. 5, was in Eagle Lake, at a depth of 78 ft.’ - As 
the ponds freeze in winter, the temperature must be subject to continual varia- 
tion, and a single undated observation has but a limited value in this particular con- 
nection.]

the Konigsee, Obersee and Walchensee, in August '1862, at various depths. The 
results were afterwards criticised by Simony and doubt thrown on the reliability of the 
instrument. ]

[Record of observations made in the Lake of Neuchatel by Professor Ladame 
at various depths down to 90 feet on the following dates, — June 21, July 6, Ju- 
ly 11, 1839, and October 1, 1840. The instrument employed was an alcohol mini- 
mum thermometer not encased. Observations were also made by Professors Ladame 
and Guyot on February 22 and April 14, 1842, to a depth of 180 and 276 feet, using 
a thermometrographe inclosed in a thick copper tube. The observations of February 
22 are quoted above. The paper contains also a discussion of the manner in which 
heat is propagated in the lake.]
