Dr. Heuschel's Astronomical 'Observations 
Oct. 4, 1810. 40 feet telescope. Space-penetrating power 
191,68. Magnifying power 280. “ Having been a sufficient 
“ time at the telescope to prepare the eye properly for seeing 
“ minute objects, the 72c! of the Connoissance des temps came 
“ into the field. It is a very bright object.'' 
“ It is a cluster of stars of a round figure, but the very faint 
“ stars on the outside of globular clusters are generally a 
“ little dispersed so as to deviate from a perfect circular form. 
‘‘ The telescopes which have the greatest light shew this best.^’ 
“ It is very gradually extremely condensed in the centre, 
“ but with much attention, even there, the stars may be dis- 
“ tinguished." 
“ There are many stars in the field of view with it, but they 
‘‘ are of several magnitudes totally different from the exces- 
‘‘ sively small ones which compose the duster." 
“ It is not possible ro form an idea of the number of stars 
“ that may be in such a cluster ; but 1 think we cannot esti- 
mate them by hundreds." 
“ The diameter of the cluster is about | of the field, which 
gives “ 1' 53",6." See fig. 17. 
Sept. 4, 1799. 40 feet telescope, power 240. ‘‘ I examined 
‘‘ the 2d of the Connoiss. It appeared very brilliant and lu- 
minoLis." 
“ The scattered stars were brought to a good, well deter- 
“ mined focus, from which it appears that the central con- 
densed light is owing to a multitude of stars that appeared 
“ at various distances behind and near each other. I could 
“ actually see and distinguish the stars even in the central
