Prof. Frazer, from the Committee appointed at last meeting 

 to observe the Solar Eclipse of the 26th ultimo, made a report 

 embodying the results of observations made at various places 

 in and near Philadelphia, as follows: 



The committee appointed to observe the eclipse of the sun on 26th 

 May, 1854, report that observations were made by Mr. Fisher Long- 

 streth, at the observatory attached to the Friends' Central School in 

 Cherry street; by Mr. T. Wagner and Mr. Riggs, at the observatory 

 of the former gentleman; by Mr. Justice and Mr. Trego, at the State 

 House; and by Profs. Kendall and Frazer at the Franklin Institute. 



Mr. Longstreth's observations were made with a 3^ feet telescope, 

 and red screen ; owing to the heat, the object glass was reduced from 

 3 inches to 1 inch aperture. 



Mr. Wagner used a refracting telescope by Jones (London), 5 feet 

 focal length; object glass 3| inches, by Tully, reduced by a cap 

 about one-half; power, 100; screen, dark red. 



Mr. Riggs used a telescope by Utzschneidcr & Fraunhofor, with a 

 red screen ; power about 30. 



Mr. Justice observed with the DoUond telescope, belonging to the 

 Society; power about 85; screen glass dark smoky green, giving an 

 apparently colourless image of the sun; and a small glass by Merz, 

 power about 30. 



Mr. Trego used a glass by Blunt, power about 24; screen glass 

 smoke colour.
