    ADDENDA TO THE ESSAY ON THE AURORA BOREALIS. 1834. Since my removal from Kendal to Manchester, | have not had so good opportunities of making ob- servations on the appearances of the Aurora borealis, partly from the obstructions of view by buildings in a large town, and partly from the effects of greater distance from those regions where the au- rore most abound, but principally, from the late period being one in which the phenomena were less common than they had been previously. ! have not, however, been inattentive to the subject, and have noted in my journal all such appearances as seemed well authenticated, whether communicated by friends or through the medium of the public journals. It may be proper, in this place, to subjoin a list of those appearances, with their dates, as the pre- sent work was published originally with more es- pecial reference to this peculiar meteor. Explanation of the abbreviations used, as reference to authorities, in the following list of Aurore Boreales. Where no reference is given, it is to be considered the Author's own observation. R. Refers to such observations as were reported to have been made by persons deemed competent. FF
