THE NEW ORLEANS MEETING OF TEE 



AMERICAN ASSOCIATION FOR THE 



ADVANCEMENT OF SCIENCE. 



The permanent secretary announces that 

 owing to delayed negotiations with the rail- 

 roads with regard to rates and on account of 

 a printers' strike in Washington, the publica- 

 tion of the preliminary announcement of the 

 ISTew Orleans meeting has unfortunately been 

 delayed. It is probable, however, that the an- 

 nouncement will be mailed to all members of 

 the association from Washington about De- 

 cember 8. Additional information to that con- 

 tained in the announcement will be found in 

 Science of December 15 and December 22. 



As announced last week the Southeastern 

 Passenger Association, including practically 

 the territory south of the Potomac and Ohio 

 Rivers and east of the Mississippi, has granted 

 a one-fare round trip rate plus 25 cents, and 

 the Central Passenger Association has now 

 adopted the same rate. - Other passenger asso- 

 ciations will either adopt this rate or with the 

 northern associations a one-fare and one third 

 rate to their southern terminals, the one-fare 

 rate holding for distances south of these ter- 

 minals. The latter plan has been adopted by 

 the Trunin Line Association, which includes 

 New York, New Jersey, nearly all of Pennsyl- 

 vania, Delaware, Maryland and West Virginia 

 north of Charleston. This will make a very 

 reasonable rate amounting to about $36 from 

 ISTew York City and $27.75 from Washington. 



The plans for the meeting are practically 

 completed and many interesting features will 

 be announced in addition to those already men- 

 tioned in these columns. The social features 

 will include a smoker at the Washing-ton Artil- 



lery Hall on Friday night, December 29 ; a 

 general reception on the night of December 30, 

 an excursion on December 31 to the large 

 sugar plantations, receptions by private citi- 

 zens of New Orleans, and personally conducted 

 trolley rides over the city, particularly through 

 the most interesting old and historic parts. 

 Visits will also be arranged to the many in- 

 dustrial establishments and to the new muni- 

 cipal drainage plant. 



The symposium to be held under the aus- 

 pices of Section K on the subject of yellow 

 fever and other insect-borne diseases is at- 

 tracting much attention, and many prominent 

 experts have accepted invitations to speak. 

 Professor Parlbw, the retiring president, has 

 announced as his subject ' The Popular Con- 

 ception of a Scientific Man at the Present 

 Dajr.' 



On Monday evening the American Chemical 

 Society will hold it annual subscription din- 

 ner, and the visiting members of the Sigma Xi 

 will also hold a dinner at a time and place to 

 be announced later. The hotels have an- 

 nounced reasonable rates, and a full list of 

 these rates, together with a list of boarding 

 houses, will be printed in the preliminary an- 

 nouncement. 



The permanent secretary reiterates the an- 

 nouncement on the authority of the best sani- 

 tarians in the country that there should not be 

 the slightest fear in the raind of any member 

 of the association that New Orleans will be 

 an unhealthy place at the time of the meeting 

 or that it is now unhealthy. In fact, the 

 brilliant sanitary achievement of last summer 

 in wiping out the yellow fever epidemic should 

 greatly add to the interest of a visit to New 

 Orleans at this time. This fact and the gen- 

 eral interest attaching to this unique city, 

 together with the unprecedentedly low railroad 

 rates, should combine to bring about an espe- 

 cially large attendance and particularly from 

 the north and east. A visit to New Orleans 

 and its vicinity is in many ways as interesting 

 as a visit to France or Spain.
