176 PHILOSOPHICAL TRANSACTIONS. [aNNO 1715, 



Ventura, which they soon after fell in with. He writes that it began at 6^ 49'", 

 and ended at 8^ 47^" ; this latter very exactly, though not quite so nice as to 

 the beginning. 



From Germany we have received the following accounts. 



At Nurenburg, the beginning and greatest obscurity could not be seen for 

 clouds, but the end happened at 11^ 10^"". 



At Hamburg, the beginning was observed at 8^ 57^"; the greatest obscurity 

 at 10*^ 5"" 30% when 1 14- digits were darkened. The end could not be seen for 

 clouds. 



At Kiel in Holstein, the beginning 9^ 14"^; the greatest obscurity 10*^ 19"' 

 20^, and the quantity then eclipsed 1 1 digits 20'. The end was at 1 1^ 29"^. 



At Berlin, the beginning could not be seen for clouds ; but the greatest ob- 

 scurity was at 22 min. past 10, when 11 digits were eclipsed. The just end 

 was at 11^ 34"^. 



At Franckfort on the Maine, the eclipse began at 8*^ 50"^; the greatest dark- 

 ness at 10*^ 11% but perhaps should be JO^ 10 min. the digits being 10 and 34 

 min. The end was observed at 10 min. past eleven. 



In a Dutch print, entitled Nouvelles Literaires, published at the Hague, 

 there is an account of the observation of this eclipse at Upsal in Sweden, by 

 M. Jo. Waller, professor of mathematics in that university, who was very care- 

 ful to observe it exactly ; the times being verified by three clocks perfectly 

 agreeing with each other and with the sun : but more especially by a quadrant 

 of 5 foot radius for taking the sun's altitude. By this instrument he has deter- 

 mined the height of the pole at Upsal 59° 5l' 5^". And by the same, a little 

 before the beginning of the eclipse, he found the height of the sun 39*^ 36' 42^', 

 his clocks then'showing the hour 9^^ 47"^ 50% which proves that they were very 

 near the true time. At 10^ 68™ 15% the altitude of the sun being 44° 17' 29'% 

 was the beginning of the total darkness, and at 1 1^ 2^" 24^ was the end of it, 

 alto sole 44° 29' 13'': so that here the duration of the total eclipse was 4"^ 9% 

 and the middle only one third of a minute after eleven. And lastly the end is 

 said to have happened about 4 minutes before noon, the sun being 45° 42' 6" 

 high : but in this is a manifest mistake, for it makes the time of emersion, or 

 from the middle to the end, only 55"^ 20^; whereas being so near the meridian, 

 it is certain that this emersion was the greater part of the duration of the whole 

 eclipse, and consequently more than an hour. Perhaps the times might be de- 

 duced from the altitudes only, and then the mistake might be in supposing the 

 end so much before noon as it was really after it. However, to prevent all 

 doubts, we have compared this observation with what we observed of this 

 eclipse at London, and find that in the latitude of 59° 50% the place where the
