abstract Examination of the seismic phase Sn from earthquakes in the West Indies as recorded by numerous stations in eastern North America reveals that a substantial fraction of the short-period energy carried by Sn across the suboceanic lithosphere of the Atlantic is fed into the continental crust near the continental margin and travels into North America as the crustal phase Lg. As distance within the continent increases, the Lg part of the short-period wave train becomes predominant, and can be identified at stations in northern Canada as far as 58° from the sources. Several estimates of the average Q for the attenuation of Lg in eastern North America agree upon values in the range of 600 to 1,400. Hydrophone recordings at Bermuda indicate an average Q as high as 4,000 for the attenuation of Sn in the suboceanic lithosphere. Conversion of Sn to Lg also appears to occur near the margin between the continental U.S. and the Gulf of Mexico. In this case, Sn travels northward across the Gulf from earthquakes located near the border between Mexico and Guatemala.

A New Species

A new species of Brissus is described from the lower Oligocene (Rupelian–Vicksburgian) Bridgeboro limestone of southwestern Georgia. Brissus bridgeboroensis n. sp. most closely resembles the Recent Brissus unicolor (Leske) of the West Indies and the Gulf of Mexico, but it differs primarily in features of the posterior paired petals. Brissus bridgeboroensis is the oldest known member of the genus from continental North America.

A Company

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.
