to  act  half  an  hour  and  the  excess  removed  with  sodium  thiosul- 
phate.  Comparison  of  the  purified  waters  with  the  impure  sample 
showed  that,  while  the  purification  effected  little  change  in  the 
amount  of  organic  matter  tested  with  permanganate,  ranging  from 
4*4  milligrammes  per  litre  in  the  impure  to  3  2  in  that  purified  with 
chlorine,  and  also  slight  alteration  in  the  amount  of  ammonia,  rang, 
ing  from  0-24  milligrammes  per  litre  in  the  impure  to  016  in  the 
chlorinated,  the  destruction  of  bacteria  was  most  notable,  the 
amount  in  the  original  water  counted  on  nutritive  gelatin  after 
eight  days  being  17,500  (in  what  quantity? — Ed.)  ;  in  chlorine  puri- 
fied water,  300;  in  bromine  purified  water,  190,  and  in  iodine,  only  90. 
The  writer  thus  gives  preference  to  alcoholic  solution  of  iodine  as  a 
purifier.  Attention  is  called  to  the  fact  that  all  the  water  examined 
developed  oxygen  on  standing,  the  impure  original  having  9-6 
milligrammes  per  litre  after  one  day  and  12-6  milligrammes  after 
twenty  days;  the  chlorinated,  1  r6  milligrammes  after  one  day  and 
15-3  milligrammes  after  twenty  days.  These  represent  the  extremes.

THYMOTAL. 
A  new  remedy  against  Anchylostomum  duodenale. 
Thymol  is  known  for  its  antiseptic  properties.  It  is  therefore 
administered,  internally,  especially  against  that  dangerous  parasite, 
the  Anchylostominn  duodenale^  when  Ext.  Filicis  mas  aether,  Pellie- 
tierin,  Kamala  et  t.  g.  fail. 
Anchylostomum  duodenale  is  one  of  the  special  plagues  of  warm  countries, 
especially  of  Italy.  Italians  spread  it  sometimes.  Frequently  it  becomes  of 
an  epidemic  character.  It  is  one  of  the  causes  of  chlorosis,  and  can  become 
fatal,  under  certain  circumstances.  The  "worm  "  reaches  a  length  of  18  milli- 
metres. The  sexes  are  separate.  West  India  is  especially  infested  with  it. 
How  well  it  7s  provided  for  its  deadly  work  can  be  judged  from  a  drawing 
made  by  Professor  I/euckardt,  reproduced  in  "  Practisch  wichtige  microsco- 
pische  Objecten,"  page  298  of  Hager-Mez'  "Das  Microscop,"  Berlin,  Julius 
Springer,  1899. 
The  administration  of  thymol  has  bad  after-effects  ;  it  causes 
dizziness,  intoxication,  nausea. 
Applying  the  same  process  whereby  guajacol  loses  its  strongly 
aromatic  and  burning  taste,  becomes  tasteless,  but  preserves  its 
medical  properties,  e.  g.,  converting  it  into  a  carbonate.1    Mr.  J.  F.
