THE celebration of the fiftieth anniversary of the founding of the Wisconsin Academy of

Sciences, Arts and Letters will be the occasion of an important gathering at the University of Wisconsin on April 23. Professor T. C. Chamberlin, professor emeritus of geology at the University of Chicago, will give an address on "The founding of the Wisconsin Academy of Sciences, Arts and Letters," at an all-university convocation in the morning. Professor Chamberlin is one of the two or three living members who helped to establish the academy in 1870 for the purpose of preserving the scientific studies of the state. He was then professor of science at Whitewater Normal School. He was president of the University of Wisconsin from 1887-92, when he became professor of geology at the University of Chicago. The regular business meeting of the academy will be held in the morning, April 23, an alluniversity convocation will be held in the afternoon, and a banquet in the evening.

President E. A. Birge, of the University of Wisconsin, will preside at the afternoon meeting. Professor John M. Coulter, of the University of Chicago, will speak on "The relation of the local academy to the national organization," and Professor C. E. Allen, of the University of Wisconsin, will speak on "The proposed plan of affiliation of the local academies with national organizations."

The Wisconsin Academy was the first important means in the state of gathering scientific

material and has preserved it in annual volumes, published at state expense. An anniversary volume of the proceedings, containing the papers of the members, will be published as the twenty-first volume of the Transactions of the academy.

A bronze medal commemorating the 50th anniversary of the founding of the academy is to be struck for the anniversary meeting. The medal will bear on its face the portraits of Dr. Increase A. Lapham, pioneer archeologist and antiquarian, Philo R. Hoy, naturalist and antiquarian whose collection of birds is in the Racine Public Library, George W. Peckham, authority on certain groups of spiders whose collection of the Attidæ species is in the Milwaukee Public Museum, Professor R. D.

Irving, geologist and at one time head of the U. S. Geological Survey in the northwestern states, and Professor William F. Allen, authority on Roman history and antiquities. All were prominent in the early history of the academy. Under the portraits will appear the words, "Wisconsin Academy of Sciences, Arts and Letters, 1870-1920, Natural Species Ratioque." The obverse will bear the figure of Minerva, holding the lamp of learning, and the words "Nature Species Ratioque."

AT the meeting of the Executive Committee of the Massachusetts Society for Mental Hygiene held March 9, 1920, the following resolution was adopted:

The directors of the Massachusetts Society for Mental Hygiene desire to express their deep sorrow and their great sense of loss in the death of Professor Elmer Ernest Southard. To many of them he was a warm personal friend whom they will sorely miss. His great natural abilities, his extraordinary powers of insight and deduction were most valuable to the society in which he took an active and stimulating interest.

The directors feel that they have lost not only a most valuable adviser and colleague but one on whose sympathy and friendship they could always depend.

DR. GEORGE EGBERT FISHER, professor of mathematics in the University of Pennsylvania, died on March 28, aged fifty-seven years. The following resolutions have been passed by faculties of the university:

Professor Fisher's connection with the faculty dates from 1889, when he was appointed assistant professor of mathematics.

Earnest in purpose, lofty in ideals, a patient and inspiring teacher, he invariably won and held the respect and love of his students.

We of the faculty wish to bear testimony to our appreciation of the profound scholarship of our departed colleague, and to our recognition of his exceptionally deep and abiding love for mathe

matics. It was always his aim to foster a more general interest in this subject. We would testify also to his ready and sympathetic cooperation in all that was for the best interests of the university.

A VERY interesting note by Hansen on the flagellation of the legume nodule organisms (Rhizobium) appeared recently in this journal.1 There has been a dispute for some time as to whether these bacteria have one or several flagella. Burrill and Hansen not long ago2 claimed that they are monotrichic organisms, whereas various other investigators, including the present writers have observed peritrichic flagella. Hansen now says that he, too, has found peritrichic flagella on cultures obtained from clover, vetch and alfalfa, and calls attention to the fact that his earlier studies had been on organisms from cowpea and soy bean. Hence he suggests that there may be two different groups, one peritrichic and the other monotrichic. It is, indeed, gen

erally recognized that the organisms of cowpea and soy bean differ from the other varieties of Rhizobium in certain cultural features, primarily in respect to vigor of growth.

Hansen's suggestion is very interesting, but does not explain all the facts that have been observed. Wilson has found peritrichic flagella on cultures of the soy bean organism. To be sure, as insisted by Hansen, Wilson has not published any photomicrographs; but the statement he makes is definite and no one need question it. We have seen one of Wilson's microscopic preparations (soy bean organism) and also one of Hansen's (cowpea organism); and find four or five flagella on some of the bacteria in Wilson's preparations, but only one each on those in Hansen's.

Upon enquiry we find that Wilson's cultures were sometimes as old as 28 days at the time of staining; while it appears from Burrill and Hansen's paper that their preparations were only a few days old. In this connection it is an interesting fact that a certain organism (belonging to a different group) studied in this laboratory was found to have a single polar flagellum when a few hours old, but two or three polar flagella when a day or more old. This naturally raises the question whether the cowpea and soy bean organisms may not be monotrichic in young cultures and peritrichic when they are older. This suggestion is further borne out by the fact that Hansen found (as shown by statements in his text and by his photomicrographs) the single flagellum to be attached at the corner or even at the side more often than exactly at the pole. This is just what would be expected if it were a matter of chance which one of the peritrichic flagella developed first in a young culture.

Ever since the appearance of Burrill and Hansen's paper we have wanted to investigate the truth of the matter. As we have not had the chance to do so, we take this occasion to put the idea in print that any one else inter

ested in this rather puzzling question may study it to see whether there is anything in the theory suggested here.



THE American Association for Labor Legislation calls attention to the very serious evils arising from the lack of a pension system in the government bureaus at Washington. They say: "It is now reported that of a total of 878 employees in one federal bureau in Washington, 303 are over 65 years old, 104 over 75, and 29 over 80. The Treasury Department alone has 1,000 aged who average only 25 per cent. efficiency-1,000 drawing full pay for work that could be done by 250."

This is a matter which concerns scientific men. I remember several years ago calling on one of the most eminent zoologists in the National Museum. I found that he was writing all his letters by hand, because the stenographer assigned to him was too old to do the work. He explained that of course he could not, or would not dismiss her; but as a result he was left without the assistance he should have had. I recall a scientific assistant, retained by a bureau long after he had ceased to be able to do anything of value, but required to spend his days at his desk. No one would have thought of turning him away unless he could be adequately provided for. The effect of these conditions on the progress of science is obvious and lamentable.

It appears that there is now a bill before Congress, providing for retirement on part pay at 65, the employee contributing 24 per cent. of wages, the government the rest. It should certainly be supported.




THE Weather Bureau is compiling observations of the auroras of March 22-23, 23-24,

and 24-25, 1920, as seen in the United States, or elsewhere, with a view to publishing a detailed account of this remarkable display in the March, 1920, issue of the Monthly Weather Review. It is hoped that those who observed an aurora on any of the dates mentioned will notify the bureau, and if details were noted will send copies of their notes. Information about any display which may be seen on April 18, 27 days after the brilliant night in March, or auroras observed on other dates in 1919 or 1920 will also be appreciated. Communications should be addressed to "Editor, Weather Bureau, Washington, D. C.," and should reach Washington by the end of April.

AFTER years of half-hearted consideration Congress seems about to pass a bill for the retirement and pensioning of employees in the federal service. It will be applicable only to those in the classified service, about 300,000 in all. It is a measure of justice and at the same time a measure of economy, for the government hasn't been heartless enough to turn the superannuated loose. Thousands of them retain their places, but do little or no work.

The government retires employees in the military and kindred services. It ought to set a similar standard for faithful civil employment. The retirement age in the army is sixty-four, and in the navy sixty-two. Taking into consideration the easier conditions of civil employment, the bill which has just passed the Senate fixes seventy as the civil retirement limit. The allowances will vary according to length of service, from thirty years down to eighteen years. Persons disabled through disease or injury in the line of duty may be retired before reaching seventy.

Another distinction is to be made between civil and military beneficiaries. An annuity assessment of 2 per cent. will be levied annually on the salaries of civil employees until a retirement fund is accumulated. This assess
