CALENDAR OF SOCIETIES. 



Royal Meteorological Society, London. 



June 18.— W. Ellis, On the Difference 

 produced in the Mean Temperature derived 

 from Daily Maximum and Minimum Read- 

 ings, as depending on the Time at which 

 the Thermometers are read. In the publi- 

 cations issued by the Greenwich Observatory 

 authorities, the maximum and minimum 

 temperatures are those referring to the civil 

 day from midnight to midnight. At many 

 stations the observers only read their instru- 

 ments once a day, viz., at 9 a.m , when the 

 reading of the maximum thermometer is 

 entered to the preceding civil day, and the 

 reading of the minimum thermometer to 

 the same civil day. Such stations are 

 called "climatological stations." The au- 

 thor has tabulated the Greenwich maximum 

 and minimum temperatures according to 

 both methods for the years 1886-89, and 

 finds that the climatological maximum and 

 minimum means are in excess of the civil- 

 day means. W. L. Dallas, On the Distri- 

 bution of Barometric Pressure at the Aver- 

 age Level of the Hill Stations in India, and 

 its Probable Effect on the Rainfall of the 

 Cold Weather. The weather over India 

 during January, 1890, was very dry, and in 

 marked contrast to that which prevailed 

 during January, 1889. The distribution of 

 barometric pressure was, however, much 

 the same in both months. The author has 

 investigated the records at the hill stations, 

 and has prepared charts showing the distri- 

 bution of barometric pressure from both 

 high and low level stations. From the 

 high-level charts it appears that the mean 

 barometric gradient in 1889 was rather more 

 than twice that in 1890, and considering 

 what is known of air movements, even at 

 moderate elevations above the earth's sur- 

 face, it may be assumed that these differ- 

 ences in pressure were accompanied with 

 large differences of air motion; and, if it is 

 also assumed that the evaporation over the 

 Southern Ocean is in all years fairly com- 

 parable in amount, the deficiency of rainfall 

 over India in the winter of 1889-90 can be 

 attributed to diminished lateral translation 

 of vapor, owing to sluggish movements in 

 the upper atmosphere. W. Ellis, On the 

 Relative Prevalence of Different Winds at 

 the Royal Observatory, Greenwich, 1841-89. 

 The author gives the following as the aver- 

 age number of days of prevalence of differ- 

 ent winds for the forty-nine years 1841-89, 

 as derived from the records of the self-reg- 

 istering Osier anemometer: north, 40 days; 

 ^north-east, 45; east, 27; south-east, 23; 

 south, 35; south-west, 106; west, 46; north- 

 west, 23; calm, 22. A. B. MacDowall, On 

 Some Recent Variations of Wind at Green- 

 wich. J. P. Maclear, On the Action of 

 Lightning during the Thunder-Storms of 

 June 6 and 7, 1889, at Cranleigh. The au- 

 thor examined a number of trees which had 

 been struck by lightning during these thun- 

 der-storms, and found that those which 

 were struck before the rain fell were shat- 

 tered, while those which were struck after 

 the rain commenced were simply scored, 



with the bark blown otf. It seems that 

 during rain every tree is conducting elec- 

 tricity, and a disruptive discharge takes 

 place where the conductor becomes insuffi- 

 cient. This depends on the position of the 

 cloud, the amount of foliage on the tree, its 

 condition of moisture, and its connection 

 with running water. 



Natural Science Association of Staten 

 Island. 



June 12.— Mrs. N. L. Britton, A Prelimi- 

 nary List of the Mosses of Staten Island;

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists of Europe and America, and bringing them 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of " one remedy for one 

 disease " must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure eveiy ill out of a single 

 bottle, and the use of which, as statistics prove, 

 has J uined more stomachs than alcohol, A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro 

 prietors.

Fact and Theory Papers 



THE SUPPRESSION OF CONSUMPTION. 



By Godfrey W. Hambleton, M.D. 12^. 40c. 



"The inestimable importance of the subject, the 

 erainence of the author and the novelty of his work 

 all combine to render the little treatise worthy of 

 special consideration. . . . We heartily com- 

 mend Dr. Hambleton's booklet and wish there were 

 more such works."— Editorial, Boston Daily Adver- 

 tiser. 



'*It is full of facts and wisdom." — Philadelphia 

 Saturday Evening Post. 



"The book contains much of importance to the 

 medical fraternity, as well as the general populace.''' 

 — Burlington Hawkeye. 



" We commend the book to physicians and lay- 

 men." — Herold (German), Milwaukee. 



THE SOCIETY AND THE "FAD." 



By Appleton Moegak, Esq. 13°. 20 cents. 



"Mr. Morgan founds a sensible and interesting 

 address upon a text furnished by a sentence from a 

 young ladies' magazine; namely, 'Browning and 

 Ibsen are the only really dramatic authors of their 

 century.'"— iVe!<; York Smi. 



"In the little book before us the treatment of the 

 subject is dispassionate and logical. The compari- 

 son drawn throughout this monograph is between 

 Shakspeare and Browning, the subject-matter being 

 largely based on the Browning and Shakspearian 

 societies and how they came to exist. A pleasant 

 half -hour or more may be spent over the book, and 

 some useful information derived from it." — Engle- 

 toood Times. 



PROTOPLASM AND LIFE. 



By C. F. Cox. 12*^. 75 cents. 

 The author of this book was for some years presi- 

 dent of the New York Microscopical Society, and in 

 this volume he sets forth his views on the spontane- 

 ous generation theory and its relation to the general 

 theory of evolution, and on protoplasm and the cell 

 doctrine.

THE CHEROKEES IN PRE-COLUMBIAN TIMES 



By Cyrus Thomas. 12°. SI. 



Br. Thomas in this work will reverse the usual 

 method of dealing with prehistoric subjects ; that is- 

 to say, he will commence with the earliest recorded 

 history of the tribe as a basis, and trace the chain 

 back step by step by the light of the mounds, tradi- 

 tions, and other evidence, as far as possible. He 

 has already presented to the public some reasons 

 for believing the Cherokees were mound-builders, 

 but additional evidence bearing on the subject has 

 been obtained. A more careful study of the Dela- 

 ware tradition respecting the Taliegwi satisfies him 

 that we have in the Bark Record (TValam Olum) 

 itself proof that they were Cherokees. He thinks 

 the mounds enable us to trace back their line of 

 migration even beyond their residence in Ohio to 

 the western bank of the Mississippi. The object is 

 therefore threefold: 1. An illustration of the re- 

 verse method of dealing with prehistoric subjects ; 

 2. Incidental proof that some of the Indians were 

 mound-builders ; 3. A study of a single tribe in the 

 light of the mound testimony. This work will be an 

 important contribution to the literature of the Co- 

 lumbian discovery which will doubtless appear 

 during the coming two years. 



Beady at an early date. 



THE TORNADO. 



By H. A. Hazen. 12°. $1. 



Professor Hazen is one of the prominent meteor- 

 ologists connected with the United States Signal 

 Office. In this work he reviews our present infor- 

 mation as to tornadoes, severely criticising some of 

 the opinions held in regard to them up to this time. 

 No one has given a more careful study to these de- 

 structive storms than has Professor Hazen, and his 

 book will prove a decided contribution to the 

 world's knowledge. In this book will be found a 

 careful discussion of the important question of 

 Tornado Insurance now attracting so much atten- 

 tion. Hundreds of dollars m^ be saved by people 

 who are thinking of such insurance by following the 

 principles here made plain.
