expeditions was — 0'.017, the mean of these, or — 0\018, has been employed, the 

 perforated pivot being the larger. 



Although the climate of Newfoundland proved by no means favorable for obser- 

 vation of the heavens, the observers had the satisfaction of obtaining excellent 

 series of transits for time-determinations, both before and after exchanges, upon 

 every date on which longitude-signals were exchanged, whether with Valencia or 

 with Calais. Here, as in the Valencia series, those observations are given, together 

 with their reductions, upon which the longitudes depend; all the transits for Valencia 

 exchanges having been observed by Mr. Dean, and those for the Calais exchanges 

 by Mr. Goodfellow.
