Excerpt: ... third, fourth, and fifth orders partake almost exclusively of the properties of the second part.* Postscript 53. The principal facts and conclusions of this section were announced to the Society in October, 1839, and again, in June last, presented in the form in which they are here detailed. Since then, however, I have had leisure to examine the subject more attentively, and after a careful comparison of these results with those before given, I have obtained the more definite views of the phenomena which are given in the following section. Section 3 Theoretical Considerations Relating to the Phenomena Described in this and the Preceding Communications Read November 20, 1840 54. The experiments given in No. Ill of my Contributions were merely arranged under different heads, and only such inferences drawn from them as could be immediately deduced without reference to a general explanation. The addition, however, which I have since made to the number of facts, affords the means of a wider generalization; and after an attentive consideration of all the results given in this and the preceding papers, I have come to the conclusion that they can all be referred to the simple laws of the induction at the beginning and the ending of a galvanic current. 55. In the course of these investigations the limited hypotheses which I have adopted have been continually modified by the development of new facts, and therefore my present views, with the further extension of the subject, may also require important corrections. But I am induced to believe, from its exact accordance with all the facts, so far as they have been * (The above paper was reprinted in Silliman's American Journal of Science, April 1841, Vol. XLI, pp. 117-152.
