This  treatise  deals  with  the  chemical  analysis  of  industrial  prod- 
ucts, which  is  of  great  importance  in  the  purchase  of  raw  materials, 
in  the  control  of  manufacturing  processes  and  in  the  determination 
of  the  value,  impurities  and  adulterations  of  the  finished  products. 
In  many  cases  numerous  methods  are  given  in  the  literature, 
some  of  which  are  equal  in  accuracy  to  exact  scientific  investiga- 
tions, while  others  require  less  precision  and  yield  results  relative 
only  to  the  procedure  employed ;  certain  states  have  issued  official 
standards  and  in  many  cases  industrial  concerns  fix  beforehand  the 
methods  to  be  employed  for  the  analysis  of  the  products. 
It  is  the  purpose  of  this  book  to  give  methods  and  standards  for 
commercial  analysis  which  have  been  either  officially  prescribed  or 
repeatedly  tested  in  the  laboratories  under  the  author's  direction. 
Vol.  I  deals  with  the  analysis  of  potable  waters,  chemical  prod- 
ucts, fertilizers,  cement  materials,  metals  and  alloys,  fuels,  tar  and 
its  derivatives,  mineral  oils  and  fatty  substances  and  their  industrial 
products.  The  first  chapter  deals  with  the  analysis  of  water  for 
potability  and  partial  and  complete  analyses  for  industrial  purposes. 
The  second  chapter  treats  upon  over  a  hundred  different  chem- 
ical products  arranged  alphabetically  without  regard  to  their  organic 
or  inorganic  origin,  from  acetone  and  aniline  to  sulphur  in  its  various 
forms  and  including  the  important  acids  and  their  salts  and  such 
compounds  as  chloroform,  ether,  bleaching  powder,  alum,  etc. 
Then  follow  chapters  (III  to  X)  on  certain  classes  of  substances : 
Fertilizers  giving  general  methods  and  a  special  part  for  the  exam- 
ination of  particular  kinds.  Cement;  limes  and  cements,  giving 
chemical  and  technical  tests.  Metals  and  alloys ;  of  which  a  large 
number  are  treated,  such  as  iron,  special  steel,  aluminum,  brass, 
bronze  alloys,  etc.,  metallic  platings.  Fuels ;  chemical  analysis  and 
calorific  value.  Coal  tar  and  its  products.  Mineral  oils  and  their 
derivatives;  chemical  and  physical  tests.  Fatty  substances;  general 
methods  of  analysis,  with  special  parts  given  to  vegetable  and  ani- 
mal oils  and  fats,  marine  animal  oils  and  waxes.  Industrial  prod- 
ucts from  treatment  of  fatty  matter ;  as  specially  treated  oils  (boiled, 
hydrogenized,  etc.),  soaps,  glycerin,  etc. 
The  book  is  well  and  concisely  written  and  excellently  translated 
and  unnecessary  repetition  is  avoided.  In  the  examination  of  ma- 
terials a  brief  description  is  given,  the  adulterants  and  impurities 
likely  to  be  present  stated  and  qualitative  (and  when  important, 
quantitative)  tests  given  for  their  detection  or  determination  and,  in
