XVI. Observations on the late Solar Eclipse. By Thomas 

 Squire, Esq. 



To the Editors of the Philosophical Magazine and Annals. 



Gentlemen, 



T^HE clay with us was rather unfavourable for observing 

 -■- the late solar eclipse ; I could not see the beginning, as 

 the sun was obscured by clouds ( ^- and r-.-) at the time. But 

 at about two minutes after 10 M. S. T. the sun became visible 

 through the passing nascent cumidi, when the obscuration 

 was veiy considerable on the north-west part of the sun's disc. 

 The eclipse continued to be visible at intervals till near the 

 middle, when a dense cumulostratus again obscured the sun, 

 but towards the end the air became clear, and continued so 

 till the termination of the eclipse; and which took place 

 here at 12*^ 0™ 54^ mean solar time. Latitude of the place 

 51° 41' 41"'6 north. Longitude 27 seconds in time east of 

 Greenwich. The above time reduced to that at the Royal 

 Observatory gives 12"^ 0'" 27'. Probably the end here was 

 absolutely rather later than at Greenwich, owing to the effects 

 of the lunar parallax, the moon being a little more depressed 

 from our northern situation. . 



The above observations were made with one of Dollond's 

 achromatic telescopes, and power of 80. The time was de-. 

 duced from correct altitudes of the sun, taken with an excel- 

 lent reflecting circle made by Troughton, having at the same 

 time the latitude of the place and sun's declination given. 



I remain, Gentlemen, yours truly, 

 Epping, Dec. 15, 1826. Thomas SgUlRE. 



XVn. On Fustic (MoYU?. imctov'ins), and its Ajjplication to 

 the Dyeing of Yelloro, Green, Olive, and Bro'wn. By 

 E. S. George, Esq. F.L.S.* 

 npHE wood of the Mortis tinctorius is employed in dyeing 

 -*■ those shades of yellow in which intensity of colour is of 

 more importance than brilliancy, and in all the range of co- 

 lours formed by the mixture of yellow, blue, and red. 



For those colours in which the sulphate of indigo is em- 

 ployed to give the blue, it is of great value, resisting tlie ac- 

 tion of free sulphuric acid in a higher degree than any other 

 yellow colouring matter.
