the spontaneous offers of assistance of H. H. the Chief of Jamkandi. I 

 have no great fears about the weather ; but of course one may be disap- 

 pointed. There is certainly a better chance there than at any point on the 

 east coast. Yours truly,

These are all of the class globular clusters. They are all 

 described as very bright or bright, and most of them well 

 resolved. Their spectra were recognized, without excep- 

 tion, as continuous, and that generally without difficulty ; 

 but 2068 and 4211 were very faint in the spectroscope. 

 The spectrum of 4307 was unusually bright, and was 

 visible from about D to about F. No further details ap- 

 pear necessary about these. 



The following "planetary nebulae" have been recognized as showing 

 monochromatic spectra : — 



No. 1843. Faint monochromatic light at D + 2'22 (May 9th). 

 No. 2076. Faint monochromatic light, distinct, but not measured (May 

 10th). 



No. 1565. Faint monochromatic light, spectrum not seen until the sixth 



time of examination (May 14th). 

 No. 1801. Monochromatic spectrum suspected only (May 16th). 

 No. 3229. "Very bright; round; barely resolvable." Spectrum clearly 



continuous. 



No. 3606. "Very remarkable; very bright; very large." Continuous 

 spectrum distinctly. 



No. 4189. "Bright; pretty large ; partially resolved." Continued spec- 

 trum (May 16 th). 



No. 4421. "Bright; small; well resolved." Continuous spectrum seen 



pretty easily ? very bright; pretty large (May 18th). 



No other nebulae have been recognized (since the previous report) as 

 having positively either monochromatic light or continuous spectra ; but 

 the following list shows those which are believed to be continuous. 

 No. 3227. " Very bright; large." 

 No. 3397. "Very bright; pretty small." 



No. 3477. "Very bright; small; round; a star of the 10th magnitude 

 following." 



No. 3504. " Very bright ; pretty small ; round." 

 No. 3706. "Remarkable; very bright; very large." 

 No. 2341. "Bright; pretty large." 

 No. 2586. "Bright; pretty large ; barely resolvable." 

 No. 3214. "Bright; pretty large."
