352 Annual Report of the Consulting Chemist. 
I have further to report, that in no year have I received so 
many samples of water for examination. As many as 61 samples, 
of drinking-water were submitted to me for analysis in 1874, a 
good many of which I found largely contaminated with sewage, 
yard-drainage, and similar obnoxious liquids. The results of 
the analyses of these waters fully confirm the opinion which 1 
expressed in a former Report, that the water with which country 
houses and villages are supplied is frequently largely impregnated 
with animal-refuse products, and is decidedly injurious to the 
health of those who drink it. 
In view of the importance of this subject, I am preparing for 
the spring number of the ' Journal ' a paper on the composition 
and qualities of drinking-waters, and on waters for the supply of 
steam-boilers and general domestic purposes. 
The following are the papers contributed by me to the pages 
of the February and August numbers of the ' Journal ' for 
1874 :— 
1. On the Composition of Waters of Land-drainage. 
2. Field-experiments on Permanent Pastiu'e. 
3. Report on the Composition of Thirteen Samples of Peruvian Guaim. 
sent by the Secretary of the Admiralty to the Royal Agricultural 
Society. 
4. Annual Report for 1873. 
Analyses made for Members of the Royal Agricultural Society, December 
1873, to December 1874.
