 42, 51, 52, 53, 56, 57, 59, 60, 63, 66, 68, 71, 72, 73, 74,

 158, 159, 161, 162, 163, 168, 170, 171, 177, 178, 183, 184, 

 188, 192 and 195 ought to be condemned as unfit for 

 family use; while Nos. 1, 3, 6, 9, 10, 12, 15, 16, 17, 20, 

 33, 35, 39, 43, 44, 45, 46, 47, 48, 50, 55, 61, 64, 65, 67, 70,

 179, 185, 187, 190, 191, 194, 196 and 200 must be con- 

 sidered suspicious. 



Parties sending on water for analysis ought to be very 

 careful to use clean vessels, clean stoppers, etc. The sam- 

 ples should l)e sent on without delay after collecting. One- 

 half gallon is desirable for the analysis. 



The examinations of water, carried on at the station by 

 request, are for various reasons confined simply to a chemical 

 examination regarding the presence or absence of foreign 

 injurious matter due to infiltration from objectionable 

 sources (sewage, etc.). The recognition of the presence and 

 absence of objectionable bacterial growth is left to experts 

 in that direction.
