Bottles,  from  What  Are  They  Fashioned  ?  is  the  title  of  a 
paper  recently  contributed  by  Mr.  E.  O.  Rowland  to  the  Edinburgh 
Chemists'  Assistants  and  Apprentices  Association.  The  writer  of 
the  paper,  after  giving  an  interesting  historical  account  of  the  origin 
and  development  of  glass  manufacture,  gave  a  detailed  account  of 
the  various  materials  and  processes  employed  in  the  making  of 
glass.  The  composition  of  the  several  kinds  of  bottle  glass  was 
given  as  follows : 
White  glass  for  ordinary  moulded  bottles,  sand,  64;  lime,  6; 
carbonate  of  sodium,  23  ;  nitrate  of  sodium,  5. 
White  flint  glass  containing  lead,  sand,  63  ;  lime,  5  ;  carbonate  of 
sodium,  21  ;  nitrate  of  sodium,  3  ;  red  lead,  8. 
Ordinary  green  glass,  sand,  63  ;  carbonate  of  sodium,  26;  lime,  11. 
Sand,  lime  and  sodium  carbonate  are  the  ordinary  bases  of  glass, 
the  sodium  nitrate  is  added  as  a  decolorizing  agent  or  wash. 
The  blue  tint  of  poison  bottles  is  obtained  by  the  addition  of 
black  oxide  of  cobalt  to  the  molten  glass.  The  green  tint  of  actinic 
glass  is  obtained  in  the  same  way  by  adding  potassium  bichromate, 
while  the  amber  tint  is  usually  obtained  by  the  addition  of  manga- 
nese dioxide.    (Phar.  Jour.,  1904,  page  96.) 
Achroin. — This  is  said  to  be  an  aromatic  liquid  having  a  specific 
gravity  of  1-055,  an^  a  boiling  point  of  21 8°  C. 
It  is  to  be  given  in  capsules  of  0  25,  as  an  antiseptic  in  affections 
of  the  urinary  tract.    {Slid.  Deut.  Apoth.  Zcit.,  1903,  page  904.) 
Adulterated  Spike  Oil. — E.  J.  Parry  and  C.  J.  Bennett  {Chem. 
and  Drug.,  1903,  page  1011)  report  that  large  quantities  of  adul- 
terated oil  of  spike  are  found  on  the  English  market.  The  specific 
gravity,  optical  rotation  and  solubility  are  within  the  limits  given 
by  most  authorities,  but  careful  examination  will  usually  reveal  the 
presence  of  one  or  more  foreign  bodies. 
The  usual  adulterants  are  oil  of  turpentine,  oil  of  rosemary  and 
safrol. 
Adulterated  Citronella  Oil — Parry  and  Bennett  (Chem.  and 
Drug.,  1903,  page  1061)  found  20  per  cent,  of  alcohol  in  a  shipment 
of  citronella  oil  recently  imported  into  England. 
This  adulterant,  the  writers  think,  is  a  particularly  dangerous  one 
when  the  oil  is  bought  or  sold  by  Schimmel's  test. 
Schimmel's  test  for  citronella  oil :  The  oil  should  give  a  clear 
solution  with  1  or  2  volumes  of  80  per  cent,  alcohol  at  20°  C,  and
