the  seed  30  to  40  grammes.  The  fruit  contains  no  strychnine  and 
only  a  trace  of  brucine.  This  occurs  mostly  in  the  kernel,  where  it 
amounts  to  0-05  per  cent.  The  toxic  substance  is  probably  a  gluco- 
side,  and  it  is  said  that  1  part  of  the  fruit  macerated  in  10,000  parts 
of  water  will  kill  fish.  So  far  as  known,  it  does  not  affect  frogs  or 
mammals.  (Phar.  Jour.,  March  28,  1908,  page  413,  from  Jour. 
Phar.  ct  Chim.) 
Vanilla  Statistics. — The  total  crop  of  vanilla  for  the  season  1907- 
1908  is  estimated  to  be  475  tons,  or  about  75  tons  in  excess  of  the 
previous  season's  yield.  The  source  of  this  supply  is :  Mexican, 
100  tons  ;  Tahiti,  120  tons  ;  Bourbon,  40  tons  ;  Seychelles,  65  tons ; 
Comores  and  Mayotte,  80  tons;  Madagascar  and  Nossi-Bes,  50  tons  ; 
Mauritius,  3  tons;  Ceylon  and  Java,  7  tons;  Fiji  and  Zanzibar,  4 
tons;  Guadeloupe  and  Martinique,  6  tons.  {Client,  and  Drug.,

Arhovin.— This  is  described  by  the  Journal  of  the  American 
Medical  Association  as  "  A  proprietary  in  process  of  evolution."  It 
was  originally  described  by  the  manufacturer  as  "  thymyl  benzoate 
of  diphenylamine  ;"  later  this  was  changed  to  "  a  chemical  compound 
of  diphenylamine,  thymol  and  benzoic  acid."  A  still  later  descrip- 
tion asserts  that  "  Arhovin  consists  of  diphenylamine  and  thymol- 
benzoic  acid  ethyl  ester  in  molecular  proportions."  This,  the 
Journal  of  the  American  Medical  Association,  points  out  is  an  evolu- 
tion from  the  atomic  to  the  molecular,  and  from  the  specific  to  the 
general,  so  that  we  may  confidently  expect  to  hear  that  this  much- 
advertised  synthetic  has,  in  time,  become  a  mere  mixture.  (Jour. 
A.  M.  A.,  May  9,  1908,  page  1-541.) 
Arsenogen. — This  is  said  to  be  a  combination  containing  16  4  per 
cent,  of  iron,  2  per  cent,  of  phosphorus  and  14  per  cent,  of  arsenic 
with  paranucleinic  acid.  It  has  been  recommended  as  a  general 
tonic.    {Phar.  Zeitg,  1908,  page  280.) 
Arthvisin. — This  is  a  name  given  to  acetylsalicylamide,  and  prob- 
ably has  no  distinct  advantages  over  the  many  other  well-known 
compounds  of  acetylsalicylic  acid.    {Phar.  Zenfh.,  1907,  page  283.) 
Camphosal. — This  is  said  to  be  a  neutral  camphoric  acid  ester  of 
santal  oils,     It  occurs  as  a  brownish-yellovv  oil  that  is  readily  sol- 
uble in  ether,  alcohol,  benzol,  chloroform  and  petroleum  ether 
Unlike  santalol  and  the  oil  of  sandalwood,  it  is  but  slightly  soluble 
in  70  per  cent,  alcohol.
