Assuming  a  yield  of  7  per  cent,  of  alcohol,  it  is  estimated  that  a 
community  of  100,000  persons  would  furnish,  annually,  4,500  hecto- 
liters of  alcohol  (over  100,000  gallons).  The  gaseous  by-products 
also  have  value.  It  is  stated  that  they  can  be  utilized  in  connection 
with  the  incandescent  mantle,  and  as  fuel  for  the  distillation  process 
itself.  The  tar  may  have  value,  while  the  coke-like  residue  will  have 
some  fertilizing  properties.  Nothing  is  said  in  the  report  (as  given 
in  Oesterr.  Chem.  Zeit.,  March  1,  1903)  about  the  nitrogenous  prod- 
ucts, but  these  will  surely  have  important  uses.

Technique  des  Analyses  Chimiques,  Medicales,  Industrielles, 
de  Produits  Alimentaires  et  Pharmaceutiques,  a  l'usage  des 
Pharmaciens,  par  J.  Tarboureich  A.  Maloine.  Paris,  1903.   Price,  6 
francs. 
In  a  compact  little  volume  of  509  pages,  bound  in  flexible  cloth, 
we  have  an  attempt  to  prepare  what  may  be  called  a  vade  mecum  for 
the  pharmacist  who  wishes  to  be  able  to  analyze  a  variety  of  prod- 
ucts, such  as  would  likely  be  offered  for  examination  or  be  handled 
by  him. 
In  the  first  chapter  the  commoner  forms  of  laboratory  apparatus 
and  utensils  are  described  and  their  use  explained,  together  with  an 
account  of  important  chemical  reagents,  indicators,  volumetric  solu- 
tions, etc. 
In  the  second  chapter  we  have  in  detail  the  reactions  of  the  min- 
eral acids  and  bases,  the  organic  acids  and  alkaloids,  and  a  number 
of  tables  for  the  systematic  testing  for  acids,  bases  and  alkaloids. 
In  the  four  remaining  chapters  we  have  the  four  classes  of  com- 
pounds mentioned  in  the  title  taken  up  and  concise  methods  of 
analysis  given  for  them.  Thus  we  have  the  analyses  of  fertilizers 
(to  which,  by  the  way,  twenty-six  pages  are  given)  quite  fully 
described,  clays,  potashes  and  lyes,  alcohols,  a  few  alloys,  soaps,  sugars, 
tannins,  cements  and  petroleums ;  under  foods  and  drinks,  wine,  beer, 
cider,  vinegar,  oils,  flour,  milk  and  potable  waters;  under  medical 
products  we  have  a  very  full  section  on  urinanalysis  (twenty-nine 
pages),  urinary  calculi  and  gastric  juice ;  and  lastly,  under  pharma- 
ceutical products,  we  have,  in  the  compass  of  114  pages,  the  meth- 
ods of  analysis  or  assay  of  a  large  number  of  inorganic  and  organic 
drugs,  with  the  tests  of  the  French  Pharmacopoeia.
