Atkins' 



Filter. 



A very excellent pocket syphon- 

 filter weighing only 8 ounces, some- 

 what on the same 

 principle, is also 

 made by Messieurs 

 Atkins and Sons, 62, 

 Fleet Street, when 

 the water is purified 

 by passing through 

 a block of moulded 

 carbon, which is 

 made perfectly po- 

 rous but not hollow.
