THE POPULAR SCIENCE MONTHLY. 



alludes to the various attempts which have 

 been made to produce photographs in natu- 

 ral colors, and then states the essential feat- 

 ures of his own method. He says in conclu- 

 sion that there is much yet to be done in 

 perfecting the print-making part of the pro- 

 cess, and that for the present he is satisfied 

 to obtain perfect heliochromic prints on 

 glass, so that the result may be shown with 

 the optical lantern. He appends a reply, 

 which he made in the " Journal of the 

 Franklin Institute," to a criticism on his 

 claims by Mr. C. H. Bothamley. The bro- 

 chure has a photo-engraved portrait of Mr. 

 Ives as frontispiece. 



A lecture entitled Outlines of a New Sci- 

 ence, by E. J. Donnell, has been published 

 in the " Questions of the Day Series " (Put- 

 nam, $1). The author maintains that ex- 

 changeability is the source of economic value, 

 that all wealth is the fruit of commercial ex- 

 change, and that, when this is going on ac- 

 tively, all departments of productive indus- 

 try have health and vigor. Further, that 

 the recent enormous increase in the product- 

 ive powers of labor has created a problem 

 which demands an immediate solution ; that 

 the problem is especially pressing in this 

 country because our productive powers are 

 greater and the restrictions on our commer- 

 cial exchanges more oppressive than in any 

 other of the advanced industrial nations ; and 

 that our tariff system taxes the many for the 

 benefit of the few. 



The Trustees of the Peabody Museum of 

 American Archaeology and Ethnology have 

 begun to issue from time to time such special 

 papers as have heretofore been published in 

 connection with the annual reports, in a sepa- 

 rate form, but of uniform octavo size with 

 the reports. Each number will be sold sepa- 

 rately at a specified price, which will vary 

 according to the number of pages and illus- 

 trations. The papers will be omitted from 

 the annual reports. The first of these papers 

 published is an interesting essay by Mrs. Ze- 

 lia Nuttall, on a " Eelic of Ancient Mexico — 

 Standard or Head-dress ? " — with three col- 

 ored plates, to which is appended a note " On 

 the Complementary Signs of the Mexican 

 Graphic System." • 



The Plans for furnishing an Abundant 

 Supply of Water to the City of New York 

 from a Source independent of the Croton 



Water-shed, proposed'by John R. Bartlett and 

 Associates, contemplate the utilization of 

 the Passaic water-shed in New Jersey ; the 

 reservoirs to be located about fifteen miles 

 from the city, and the water to be brought 

 in by a tunnel under the Hudson River. 

 The supply of all the New Jersey towns 

 suburban to New York, and of Brooklyn, is 

 declared to be practicable by the same sys- 

 tem, and it is claimed that the quantity of 

 water available for this purpose is sufficient 

 to furnish them all abundantly. The water- 

 privileges of the region in question are 

 owned by private corporations, from which 

 the author has obtained concessions of the 

 right to construct reservoirs and collect and 

 use the surplus waters. In behalf of this 

 scheme, it is claimed that the Passaic water- 

 shed has three times the area of the Croton 

 water-shed, and is therefore capable of af- 

 fording a much larger supply of water than 

 can ever be derived thence ; that it is much 

 nearer to the city ; that the water can be 

 brought direct to the lower part of the city, 

 where it is most needed ; that it will be pure 

 and wholesome, and, being delivered under a 

 head-pressure of three hundred feet, will go 

 of its own force to the tops of the highest 

 houses, and with sufficient energy to be in- 

 stantly available in extinguishing fires ; and 

 that it possesses other somewhat less im- 

 portant but obviously convenient advan- 

 tages. The book in which the scheme is 

 developed and explained contains several 

 addresses and memoirs, legal opinions, and 

 opinions of experts on the various questions 

 brought out in the discussions of it, with 

 maps, plans, profiles, and views. 



Mr. Charles W. Barling, Corresponding 

 Secretary of the Oneida Historical Society, 

 has published privately, in a pamphlet of 43 

 pages, some Historical Notes concerning the 

 City of New York as it appeared in its earliest 

 days. They have been gathered from the 

 writings of the chief historians, earlier and 

 later, of the city, and from manuscript folio 

 volumes of public records. They contain 

 matter that is omitted by one or other, or 

 more, of the writers quoted from, and form 

 a picture as a whole which it will be hard to 

 find in its fullness anywhere else. The notes 

 date back to the period when trading and 

 fishing huts were first erected upon Manhat- 

 tan Island, and embrace the years between
