"Mr. W i N S L O W UPTON, Washington, D. C." ' Mr. UPTON has kindly forwarded this note, with the following memorandum: "The analysis was limited to the four principal constituents on account of the small quantity of water available. I t will be seen that the essential difference between the analysis and the others given is the amount of chlorine, which was estimated twice by very careful duplicate analyses. The lagoon water is more like that from the Irish Channel than like ocean water; that I S , it 18 slightly fresher. Since the lagoon has free outlets it is presumable that a similar analysis would have resulted from water taken from the ocean in the vicinity." v.âOBSERVATIONS O F 23 N E W D O U B L E STARS B Y MESSRS. H O L D E N AND HASTINGS. During our stay on the island Dr. HASTINGS and myself spent two or three hours of each clear night (with a few exceptions) in examining the southern sky, which is filled with objects of great interest to an observer who has only seen the stars visible from northern latitudes. In the course of this examination the following list of 23 new double and 5 new red stars was found. Our days were usually full of work, and more time was not spent m the observatories at night as it was impossible to have a quiet sleep in the day-time, owing to our contracted quarters. It 18 clear, however, from this short list, that a stay of a year or two m the southern hemi- sphere would yield a rich return to an observer who went properly equipped. Probably Quito or Santiago de Chili would be the most eligible station. During the voyage from Callao to Caroline Island, and from the island to Honolulu, Mr. U P T O N pade a number of observations of variable stars, which be communicated by him to the Harvard College Observatory.
