Excerpt from Account of the Magnetical Observatory of Dublin: And of the Instruments and Methods of Observatory Employed There
But important as these phenomena undoubtedly are, they form but a small part of the proper business of a magnetical observatory. The interest which surrounded the new subject diverted attention from the periodical and se cular changes, which had, as regards the declination at least, occupied the attention of the early observers; and yet the latter phenomena are not only as important in themselves, but also, from the long and uninterrupted series of observations which are required for the development of their laws, they stand, more than any other class, in need of the appliances of a regular observa tory. In order to embrace all that relates to the earth's magnetic force at a given place, the absolute values of the three elements which determine its di rection and intensity must be accurately observed at given epochs, and the law of their variations, both secular and periodic, traced by the help of an uni form and continuous system of observation; lastly, the knowledge Of the causes engaged in producing the irregular fluctuations is to be promoted by observa tions made in correspondence with other observatories at fixed epochs, or When ever the marked nature of the change may have arrested the attention of the observers.
