scholarly journals An account of some experiments made in the West Indies and North America, to determine the relative magnetic forces, in the Years 1831, 32, and 33

The experiments of which the results are given in this paper were made by Mr. James Napier, late Master of H. M. S. Winchester. The needles were precisely similar to those used in the experiments described by the author in a former paper; and the observations were made with great care, and repeated several times at the same places; by which it appeared that the intensities of the needles continued unchanged during the whole period of the experiments; and the mean of all those made at one place was taken as the result. From these the relative forces at different places were computed, and stated in the form of a table.

The observations for the dip were made with an instrument of modern construction, by Dollond. Each observation consisted of an equal number of readings of the position of the needle, before and after the inversion of its poles, and a mean of all the readings taken for the true dip. Tables are subjoined, containing the dips ob­served at each place; the times of making a hundred vibrations of five horizontal needles, and the mean horizontal forces computed therefrom; and likewise the results estimated in the direction of the dipping needle, compared with direct experiments made with the dipping needle itself.

The purpose of this paper is to report the results of excavations conducted in 1933, as yet unreported, and to correlate the findings with present knowledge of Jamaican and other West Indian prehistory. Descriptions of the sites and specimens may be of value to archaeologists in this area.Since 1933 great strides have been made in archaeological knowledge of the West Indies. Irving Rouse has correlated known cultures in most of the Greater Antilles and in some of the Lesser Antilles. He has established seven arbitrary time periods, I, IIa, IIb, IIIa, IIIb, IVa, and IVb, for the area (Rouse, 1939, 1941, 1948, 1951, 1952) on the basis of stratigraphy, sedation of modes, establishment of style sequences, and cross-dating of trade objects. During these periods four cultures existed. The period I culture is preceramic and is associated with the Ciboney Indians who may have come from North America. The first ceramic culture, Igneri, is associated with the Arawak Indians, who pushed north and east from the Orinoco Valley in period II. It lacks the ceremonial complex which distinguishes the two later ceramic cultures, sub-Taino and Taino, which developed in the Greater Antilles during periods III and IV, the former as a simpler variant of the latter.

It was the object in the experiments recorded in this paper, to determine the relative magnetic forces soliciting both the dipping, and horizontal needles, by observing the times of their completing a given number of vibrations at the various places visited during a period of three years, on the North American and West India Station, in Her Majesty’s Ship Racehorse. The dipping instrument used was one of modern construction by Dollond. Each observation for the dip consisted of an equal number of readings of the positions of the needle, with the face of the instrument east and west, before and after the inversion of the poles, and a mean of all the readings taken for the true dip. The instrument had two needles fitted to it, one of which being used solely for the purpose of observing its vibrations, its magnetism was therefore never interfered with, and this needle in this paper is distinguished by the letter B. The other needle was kept for the purpose of determining the dip, and the results obtained with it are given in Table I.

On Monday, October 16, 1758., Hugh Gaine reported a novelty. “Friday last,” he told his readers in the New-York Mercury, “arrived here from the West Indies, a Company of Comedians; some Part of which were here in the Year 1753.” This brief notice, which went on to assure its readers that the company had “an ample Certificate of their Private as well as publick Qualifications,” marks the beginning of the most significant event in American theatre history: the establishment of the professional theatre on this continent. The achievements of the Company of Comedians during its sixteen-year residence in North America are virtually without parallel in the history of the theatre, and have not received sufficient recognition by historians and scholars.
