On account of the uncertainty of the correction to be applied to Stampfer’s 
observations, and the small range of those of Plucker and Geissler, it appears best 
to rely exclusively on the corrected observations of Despretz, Pierre and Kopp. 
In the details of the observations, I am unable to detect any particular that warrants 
the acceptance or rejection of any one in preference to the other two. The mean 
of all three will probably approximate more nearly to the truth than any one of them 
taken by itself. Assuming 3°’945 C. to be the temperature at which the density of 
water is a maximum, in accordance with the result obtained by Messrs. Playfair 
and Joule*, the logarithms of the means, to seven places of decimals considered as 
integers, are represented with sufficient accuracy, between 4° and 25°, by 
3272(#—3-945)"—0-215(^— 3-945)".
