Lime ........ 



Oxide of iron and alumina .... 



Magnesia, alkalies, &c. ..... 



Silica ........ 



100-00 



It will be seen that this was of inferior quality, and much 

 below the guarantee. 



2. Lime Refuse from Water-softening Works. 



A sample of this material gave the following results : — 



Moisture ....... 



Water of combination .... 



Oxide of iron and alumina, carbonic acid, &c. 

 Lime ....... 



Silica ....... 



Though it was in wet condition, it contained a considerable 

 amount of lime, and, the nominal cost being only Is. per ton, it 

 might be well worth getting in cases of land requiring lime. 



3. Cement Refuse. 

 The following is an analysis of a material sent me to ascer- 



This was not really cement, but practically only siliceous 

 matter containing very little lime indeed. Its cost, 15s. per 

 ton, was much above its value, and the material was agricultur- 

 ally worthless. 



4. Hops containing Arsenic. • 



A sample of hops was sent to me to examine for arsenic, 

 the statement being made that their purchase had been refused 

 in consequence of their containing arsenic. This allegation I 

 found to be quite warranted, inasmuch as examination of the 

 sample showed it to contain over 2-5 grain of arsenic per 11).
