Miscellaneous  Results  from  the  Laboratory.

sample  of  animal  refuse,  obtained  as  above,  was  sent  to  me  for 
examination  by  Mr.  Goodden,  of  Compton,  in  Dorsetshire.  It 
was  composed  of  hair,  trimmings  of  sheep,  lamb  and  kid  skins, 
with  a quantity  of  egg-shells,  and  a large  admixture  of  lime  and 
other  earthy  matter.  Upon  analysis  it  gave —

It  contained  125  per  cent  of  nitrogen. 
The  opinion  founded  upon  its  composition  was  not  very 
favourable  to  this  refuse  as  manure,  but  Mr.  Goodden  states 
that  he  has  used  it  this  year  to  mangold-wurzel  with  good  effect. 
“ Animal  Manure * — A cargo  of  animal  refuse  was  lately 
brought  to  this  country  from  Buenos  Ayres,  and  offered  for  sale 
under  the  above  title.  It  appears  to  consist  of  the  dried  up 
carcasses  and  bones  of  animals,  from  which  the  fat  has  been 
extracted,  the  largest  bones  having  been  subsequently  picked 
out.  The  fleshy  parts  are  singularly  dry  and  brittle,  and  easily 
break  down  into  a coarse  powder.  The  bones  are  in  fragments 
of  various  sizes,  also  particularly  dry. 
Two  specimens  of  this  manure  have  been  analysed  in  this 
laboratory — the  first  for  Mr.  Hudson  of  Castleacre;  the  second 
for  Mr.  Purser  of  the  London  Manure  Company. y 
The  sample  from  Mr.  Hudson  is  evidently  a tolerably  fair 
average  ; but  that  sent  by  Mr.  Purser  would  afford  even  more 
correct  results,  as  to  obtain  it  five  tons  of  the  refuse  were  ground 
to  powder,  and  perfectly  mixed.  The  following  analysis  shows 
the  composition  of  the  manure  in  question  —

The  manure  was  offered  for  sale  at,  I believe,  51.  10s.  per  ton. 
Considered  as  a supply  of  ammonia  and  phosphate  of  lime,  its 
value  would  be  as  follows,  taking  the  mean  of  the  two  analyses 
as  the  basis  of  the  calculation: — Nitrogen,  6’40  per  cent.,  equal 
to  7*7 7 of  ammonia,  or  174  lbs.  in  a ton,  which,  at  6c?.  per  lb., 
* It  exists  in  heaps  of  almost  unlimited  extent,  being  the  remains  of  cattle 
slaughtered  for  their  hides,  and  cattle  only.  It  seems  certain  to  be  a most  valuable 
source  of  ammonia,  in  addition  to  guano.— Ph.  Pusey. 
f Dr,  Anderson,  of  Edinburgh,  has  also  published  an  analysis  of  this  manure.
