306  Annual  Report  for  1910  of  the  Consulting  Chemist. 
manure,  was  sold  by  a Co-operative  society  as  “ Pure  Dissolved 
Bones.” 
It  had  been  guaranteed  to  contain  soluble  phosphate  11 
per  cent.,  insoluble  phosphate  19  per  cent.,  and  ammonia 
3 per  cent.,  and  the  price  was  4£.  11s.  per  ton.  An  error  was 
admitted,  and,  in  the  end,  an  allowance  of  21.  per  ton  was 
made. 
3.  Fish  Guano. 
Under  this  name  was  sent  me  a material  which  cost  75 s. 
per  ton,  and  which  gave  the  following  analysis  : — 
Moisture  ........  18-73 
’ Organic  matter . ......  2532 
Phosphate  of  lime  ......  754 
Alkalies,  &c.  . . . ’ . . . 20  74 
Insoluble  siliceous  matter  .....  27-67 
100-00 
1 Containing  nitrogen  . . . . . . 1'22 
equal  to  ammonia  ......  1‘48 
This  was  nothing  but  a refuse  material  much  like  slaughter- 
house refuse,  and  the  price  was  quite  twice  as  high  as  the 
worth  of  the  material.

“ A ” cost  40s.  per  ton,  and  it  will  be  seen  that  nearly  half 
of  it  was  earthy  matter.  I should  consider  that  it  was  worth 
nothing  like  the  price  paid. 
“ B ” was  a second  sample  of  the  same,  but  with  considerably 
less  earthy  matter  than  “ A ” had.  It  was,  however,  very  lumpy 
and  wet,  and  was,  on  the  whole,  of  inferior  value  to  “ A.”
