Not illustrated. 1848 edition. Excerpt: this, however, it is affectation to pretend to great exactness, the elements which unavoidably enter into it being so variable. The quantities on which I have calculated are the greatest which are shown in the analyses, unless where the variations are given, when I have taken the extremes, and the weight of crop per acre is what I learn to be a medium between the very best and average crops; but I am most willing to confess that I am not myself practically acquainted with this part of my subject, and hence cannot answer for their absolute correctness, but have obtained them from the best authorities accessible to me. The necessary alterations, however, are easily made by any one for himself, from the data I have given, but I think they cannot be far wrong. The quantities are pounds of gypsum and bonephosphate of lime removed from one acre. Dr. Kolbe on the owidizing power of Oxygen, 'c. 285 CLXXXII. Observations on the oxidizing power of Oz-ygen when disengaged by means of Voltaic Electricity. By H. IN describing in a former paper the properties of sesquichloro-carbohyposulphuric acid, I stated that this body resists the action of the most powerful oxidizing agents, such as chromic acid, nitric acid, and even nitro-hydrochloric acid. I likewise stated the change it undergoes by the action of a voltaic current, when an easily oxidizable metal is used for the positive pole. By this means another copulated acid is produced, in which one or more equivalents of chlorine are replaced by corresponding proportions of hydrogen. I have since observed that this acid is completely decomposed on employing two platina plates as electrodes; by which arrangement oxygen is disengaged at the positive pole.
