the expanded system we had all along pursued, with the assistance of His Excellency and those gentlemen volunteers resident in the colony, who had, on every term day during our absence most zealously devoted themselves to the tedious and laborious work; and I have much satisfaction in availing myself of this opportunity of publicly expressing my thankfulness to those gentlemen who continued to afford their valuable services until the entire series of simultaneous observations with the European and American observatories was completed, and to whom all investigators of magnetic science must feel greatly indebted. The following is a statement of the several occasions on which term-day observations were obtained at the Rossbank Observatory, and the names of the gentlemen who assisted Lieutenant Kay, Mr. Scott, and Mr. Dayman in making them.
