Ethical as well as business reasons prevent the announcement of even 

 approximate results, the complete elaboration of which will appear over Mr. 

 Fuller's name early in 1897, whether in public form or as a private report to the 

 Louisville Water Company I am not informed. In any case, the matter which it 

 will contain concerns not Louisville alone, but the world as well. It is to be 

 hoped that water experts will have access to it. I believe that I am entitled to 

 say, however, that Ohio River water has been successfully filtered in quantity, 

 under the most extreme conditions, during the course of these experiments. It 

 has come from the filters clear and sparkling, on days when the chemists found in 

 the neighborhood of 3,500 parts of solids per million, and when the river showed 

 12,000 to 2o,000 bacteria to the cubic centimeter, I have counted six to ten indi- 

 vidual colonies in the filtered water. 



The equipment of both chemical and bacterial laboratories was complete and 

 thoroughly up to date. The methods for bacterial work, preparation of media, 

 classification, etc., were mostly taken from unpublished manuscripts. The steam 

 sterilizer was largely replaced by the autoclave, at a pressure of 20 pounds and a 

 registered temperature of 12(5 degrees Celsius. Color tests were a feature of the 

 chemical work, the method being that of the Massachusetts State Board of 

 Health. 



Chemists and bacteriologists can not praise too highly those members of the 

 Louisville Water Company, who, in the face of much criticism, and at such great 

 expense, have not Only made possible the solution of the question of their own 

 water supply, but that of the great cities of the Mississippi basin, and at the same 

 time placed in Mr. Fuller's hands the means of enriching our experience in the 

 handling of refractory sources of potable waters for cities.

A "Tornado" in Rush County, Indiana, August 1, 1896. By W. P. 



Shannon. 



On the first day of last August there was a destructive storm along the south- 

 ■ern line of Rush County. Approximately, we may say, it began near Milroy in 

 Rush County, and ended near Metamora in Franklin County, running from west 

 to east on a line bearing but little to the south. It was not continuous. The 

 most destructive part of its course was shortly after the beginning, on my old 

 home farm. I visited the place two days after the storm. My brother, H. F.
