(i) Miscellaneous : The director remarks : " My telescope is mounted 

 equatorially on a tripod stand. The objective is of excellent quality. 

 I can see the companion of a Lyra) and both the debilissima in ejjsilon 

 Lyrfe with ease. It also easily separates double stars only 1.5" apart. 

 Under favorable circumstauces I have seen five of Saturn's moons. I 

 have no observatory, and my observations are made from lofty windows 

 having a southerly and westerly exposure, and occasionally from the 

 roof of my residence on Brooklyn Heights. In observing Jupiter and 

 Saturn I ordinarily employ powers of 100 and 250, and occasionally 320. 

 Fcr special purposes I have used a power of 480 with good effect."
