tioned, for at least half the distance down, 

 a cloth which prevents the accumulation 

 of dust within the glass tubing. The value 

 of glass for blowing purposes is frequently 

 destroyed by minute particles of dust which 

 accumulate inside the tubes. 



In each stock room there should be a large 

 chemical sink, either of alberene or porce- 

 lain, preferably the latter, provided with a 

 flush rim. This sink is equipped with cold, 

 hot, and distilled water. Above the sink, 

 peg boards should be placed for the drain- 

 ing of glassware. It is desirable to provide 

 non-spattering nozzles for the cocks over 

 these large sinks. 



As alcohol is bought in quantity and 

 without the internal revenue tax, it is 

 necessary to keep careful control over it. 

 We have accomplished this in a most satis- 

 factory manner by securing one of the cop- 

 per tanks made by the Bramhall, Deane 

 Company. The tank is so constructed, that 

 alcohol is readily pumped into it from the 

 regular containers in which it is shipped. 

 It is provided with a safety valve to pre- 

 vent excessive pressure being created in 

 case of its being accidentally heated. It is 

 also provided with a glass gauge the entire 

 height, so that the contents may be judged. 

 The cock by which the alcohol is drawn off 

 is made with a lock. 



It will be observed from the above that 

 the teaching of one kind of chemistry is 

 localized, and, as one progressively de- 

 scends, the work of the student becomes 

 more and more specialized along lines of 

 preparatory study which he is to pursue 

 subsequently at a professional school.

with which to purchase and establish the Mon- 

 tana National Bison Herd, on the range that 

 has been provided by congress. The ultimate 

 object of this movement is to perpetuate the 

 Bison species and leave it for future genera- 

 tions of Americans. It is hoped that there 

 may be at Ravalli, Montana, in the not far- 

 distant future, a herd of a thousand pure-bred 

 bison, owned by the national government, and 

 self-sustaining, on a fenced range. 



At its last session, congress appropriated 

 $40,000 with which to buy from the Flathead 

 Indians twenty square miles of choice grazing 

 grounds, erect a fence around it and dedicate 

 it to use as a national bison range. The so- 

 ciety pledged itself to provide the nucleus 

 herd, and present it to the government, as soon 

 as the range is ready. Ten thousand dollars 

 must be obtained with which to discharge this 

 obligation. Up to date subscriptions amount- 

 ing to $3,102 have been received, and sub- 

 scriptions to complete the amount required 

 should be sent without delay to Dr. Hornaday, 

 at the Zoological Park, New York City. 



THE AMERICAN BI80N SOCIETY 

 The president of the society, Dr. William 

 T. Hornaday, has written a letter asking co- 

 operation with the society, in the effort it is 

 now making to complete a fund of $10,000 



THE COMMITTEE OF ONE HUNDRED OF 



THE AMERICAN ASSOCIATION ON 



NATIONAL HEALTH 



The president of the committee. Professor 

 Irving Fisher, states that President Eoosevelt 

 has definitely taken up the program of the 

 committee as part of his administration policy. 

 He intends to incorporate the recommendation 

 in his next message to congress — that the 

 health bureaus of the government be concen- 

 trated into a common department, from which 

 the bureaus not consistent with health and 

 education will be removed elsewhere. This 

 will be the first and most important step 

 toward a powerful department whose special 

 interest will be health and education. 



The president authorized the announcement 

 of this decision at the recent conference in 

 Washington between the Committee of One 

 Hundred, the American Medical Association, 

 the American Public Health Association, the 

 Conference of State and Provincial Boards of 

 Health, the National Child Labor Committee, 

 the Government Commission on the Organiza- 

 tion of Scientific Work, the Public Health and
