KEYIEWS  AND  BIBLIOGRAPHICAL  NOTICES. 
Twenty-ninth  Annual  Report  of  the  Inspector  of  Milk  and  Vinegar.    Boston:  Eock- 
well  &  Churchill,  printers,  1888,  8vo.,  pp.  76. 
A  comprehensive  report  giving  the  results  of  the  investigations  made  by  the 
inspector.  Prof.  Jas.  F.  Babcock,  during  the  preceding  year.  The  good  effect 
produced  by  these  continued  inspections  is  shown  by  a  number  of  tables  and 
by  graphic  representations  of  the  steady  increase  of  the  percentage  of  pure 
milk  sold  in  Boston  during  the  years,  1883  to  1887. 
Foods  and  Food  Adulterants.  Part  third:  Fermented  alcoholic  beverages,  malt 
liquors,  wine  and  cider.  By  C.  A.  Crampton,  Assistant  Chemist.  Wash- 
ington:   Government  Printing  Office,  1887,  pp.  261-399. 
The  pamphlet  enters  very  fully  into  the  examination  of  the  three  classes  of 
beverages  mencioned  in  the  title,  and  gives  interesting  details  of  the  analytical 
researches  into  the  proportion  of  the  proximate  constituents  of  the  beverages, 
iind  the  presence  of  adulterations.  We  mention  here  only  that  out  of  seventy 
samples  of  American  wines,  eighteen,  or  over  one-fourth,  had  received  an  addi- 
tion of  salicylic  acid,  and  thirteen  had  been  preserved  by  the  use  of  sulphurous 
acid,  either  as  such  or  in  the  shape  of  a  sulphite ;  one  of  the  samples  contained 
both  these  agents.  Of  forty  samples  of  red  wines  one  was  found  to  be  arti- 
ficially colored  with  aniline  red.
