In view of these discoveries it would be well to establish an 

 acid condition of the system by ten or fifteen drops of sulphuric 

 acid to the quart of water used as lemonade — the water previously 

 boiled, — and observe if sour wines might not be better for those 

 in the habit of drinking liquors, also as to whether gout and rheu- 

 matism, which are acid diatheses, conferred immunity.

Mars. 



At the jiresent time, while theories and suggestions concerning 

 the jjlanet Mars are in order, it might be well to note that, on a 

 study of Schiaparelli's chart of Mars, the systems of so-called canals 

 resolve themselves, in many cases, into radiating groups of six, 

 making hexagons, and giving the idea that the planet may be 

 solidified into a mass with tendency to hexagonal crystallization, 

 the " canals " being, for Instance, fissures on the lines of the angles 

 of crystallization. This would account for many of the peculiari- 

 ties of their appearance, while in no way opposing the present 

 existence of atmosphere, water, snow, ice, and vegetation on the 

 planet. C. W. Kempton.

La Grippe. 



The name La Grippe as used to designate the influenza, which 

 was epidemic over so large a pai't of the world during the past 

 two or three years, seems to have had a curious origin. Dr. 

 Grant, in an essay on the disease published in 1783, states that the 

 French term La Grippe is derived from an insect of that name 

 remarkably common in France during the previous spring, and 

 which the people believed contaminated the atmosphere, and 

 caused the disease. If this be true, what insect was it?

BOOK-REVIEWS. 



A Journal of American Ethnology and Archaeology. Editor, J. 

 Walter Fewkes. Vol. II. Boston, Houghton, Mifflin & 

 Co. 1892. 



feis volume is issued as one of the publications of the Hemen- 

 way South-western Archseological Expedition, and embraces, I., 

 A Few Summer Ceremonials at the Tusayan Pueblos, by J. Wal- 

 ter Fewkes; II., Natal Ceremonies of the Hopi Indians, by J. G. 

 Owens; III., A Report on the Present Condition of a Ruin in 

 Arizona Called Casa Grande, also by Dr. Fewkes. 



Dr. Fewkes, the editor of the journal and the author of two of 

 the contributions to this volume, has treated the subject of the 

 Tusayan ceremonials with much greater success than were treated 

 the Zuni rites, to which he devoted much of the first volume. 



The province of Tusayan, or so-called group of Moki Indian 

 pueblos of north-eastern Arizona, owing to their remoteness from 

 the demoralizing influence of the white-man's civilization, are 

 among the most primitive of our aboriginal tribes, and Dr. 

 Fewkes has made no mistake in abandoning the Zuiii field (to 

 which he devoted his first field-season, and to which the attention 

 of such workers as Mr. F. H. Gushing and Mrs. M. C. Stevenson 

 had earlier been drawn) in order to apply all his energies to this 

 interesting people. So far as ethnologic investigation has proved, 

 the Tusayan group (e.xcluding the Tewa village of Hano) is the 

 only existing example of a nomadic people adopting a strictly 

 pueblo life — for the Mokis, or Hopi, are a part of the great Sho- 

 shonean stock; cousins of the Utes, the Snakes, and the Coman- 

 ches, and who, centuries ago, were disconnected from the main 

 family and forced to these mesa fastnesses, where they erected 

 communal structures of stone and mud, and cultivated corn, 

 squashes, cotton, and other products in the sand-spread plains 

 below. 



Many of the ceremonials described by Dr. Fewkes in this vol- 

 ume have evidently been borrowed by the Tusayan from the 



Reading Matter Notices.
