MR. J. PEESTWICH ON SUBMARINE TEMPERATURES. 
639 
Tables of Submarine Temperatures of the Great Oceans and Inland Seas, taken 
between 1749 and 1868, arranged according to the Latitudes in each Hemisphere, and 
reduced to English measures and Greenwich Longitude. 
References to the original observations will be found in § II., in notes to the several voyages (given in order of date). Those 
alone to which (w) is attached are from unpublished documents. Those also where (M.) is added to the name will be found in 
Marcet’s paper {ante, p. 595), and not in the works of the original observers.. The temperature-readings are given as recorded by 
each observer. To obtain an approximately true reading, it is necessary to apply the correction named at p. 612, excepting 
the observations of Lenz (and Kotzebue, 2nd voyage), Du Petit-Ti-iouars (when stated “cylinder sound”), Martins, Aime, 
Shortland, Vaillant (in part), D’Urville (in part), and some of Pullen’s, and probably Ross’s and Parry’s of 1818-19. The 
correction consists in a deduction of 1° Kaiir. for every 1700 feet of depth. The figures in parentheses attached to Du Petit- 
Thouars’s observations give his original corrections of temperature and depth. A separate list of the voyages on which the 
observations were taken will be found, in connexion with the names in column VIII., in “Explanation of Map,” p. 671.
