' below, formed a natural filter. It has proved 

 * thoroughly successful in practice, as all the ohjcction- 

 ' able ingredients which jiolluted the ricer are kept hack. 

 ' We also erected a large iron tank, whence all the 

 ' sti"ong ley is pumped up and re-used, so as to form an 

 ' actual saving.^ " 



The extract concludes thus : — 



" Exjjerience has also satisfed tis, that tvith trijling 

 " exceptions, the collieries and gasworks, paper mills and 

 " manufactories, can he carried forward equally well 

 " without fouling our o?ice jjcllucid streams. In nearly 

 " every case it is hut the outlay of a little extra capital, 

 " and when great concerns are planted near, and have the 

 " use-of our streams for their commercial purposes, surely 

 " it is not asking too much that the money advanced to 

 " plant a business should include the fractional sum neces- 

 " sary to prevent the owners of that concern from wilfully 

 " and unnecessarily destroying the property and rights of 

 " their neighbours." 



In the supplement to the Registrar General's weekly 

 return for August 6th, 1866, appear the following re- 

 marks on the water supply of the east districts of London, 

 taken from Professor Frankland's Report : — 



'' The cause of the epidemic of Cholera consists, as is 

 " well known, of a zymotic matter in various degrees of 

 " activity, all over the London area, affecting the people 

 " in various ways through air, contact, and water. 

 " Hitherto in all great outbreaks here, the cholerine 

 " which this stuff may be called, has been distributed 

 " chiefly through water. 



" It is the amount of organic matter contained in this 

 " water which is of special importance in connection with 

 the outbreak of Cholera." 



From the Registrar General's Report on the public 



health, for the year 1866, 



" Dr. Farr states that there is wo apparent decline in the 

 " rate of deaths from fever He considers it extremely 

 " probable that typhoid fccer is sustained by the increas- 

 " itig contamination of the waters." 



On the 6th May, 1867, the Commissioners on the Pol- 

 lution of Rivers presented their J^nd Report which refers 

 to the Lea.
