Amyl  salicylate,  or  salicylic  acid  amyl  ester,  while  not  a  very 
recent  preparation,  appears  to  be  giving  good  results  as  an  anti- 
rheumatic and  sedative.  It  is  described  as  being  a  colorless,  refract- 
ing liquid,  having  an  odor  somewhat  resembling  salol,  soluble  in 
ether,  alcohol  and  chloroform.  It  has  been  used  as  a  substitute  for 
methyl  salicylate,  applied  externally  in  quantities  of  2  or  3 
grammes.  It  has  also  been  given  internally  in  doses  of  0-20  six  to 
eight  times  a  day. 
Organic  combinations  of  arsenic  are  increasing  at  a  rate  that  will 
soon  bring  them  up  to,  if  not  ahead  of,  the  organic  salts  of  silver 
in  number.    Among  the  newer  remedies  we  may  mention: 
Arrhenal,  said  to  be  monomethyl  sodium  arsenate ;  this  is  being 
brought  forward  as  a  substitute  for  the  older  sodium  cacodylate  or 
dimethyl  sodium  arsenate. 
Neo-arsycodyle,  a  French  preparation,  probably  analogous  to 
arrhenal. 
Atoxyl  (Pharm.  Zeit.,  1902)  is  a  preparation  of  German  origin, 
and  is  said  to  be  the  anilid  of  meta  arsenic  acid.  It  has  been  given 
in  doses  of  from  0*05  to  0  20  subcutaneously. 
Magnesium  cacodylate  has  been  recommended  as  being  more 
soluble  in  water  than  the  corresponding  salt  of  sodium,  and  also 
containing  a  larger  percentage  of  cacodylic  acid. 
Marsyle,  ferric  cacodylate,  is  supposed  to  be  an  efficient  remedy 
in  cases  of  neurasthenia,  anemia,  and  various  skin  diseases,  given  in 
doses  of  o-oi. 
Guaiacol  cacodylate-cacodiacol  has  been  reported  on  as  being  very 
unstable,  being  readily  decomposed  into  its  constituents. 
Glycerino  arsenic  acid  has  been  suggested  as  offering  a  favorable 
or  promising  method  of  administering  arsenic ;  the  similarity  exist- 
ing between  combinations  of  phosphorus  and  arsenic  is  pointed 
out,  and  the  possibility  of  substituting  arsenic  in  the  well-known 
salt  of  glycerino  phosphate  of  calcium  naturally  suggests  itself. 
(L  Union  Pharm.,  1902.) 
This  proposed  glycerino  arsenate  of  calcium  has  been  criticised 
in  some  of  the  German  journals,  who  claim  it  to  be  an  extremely 
unstable  compound,  and  consequently  not  to  be  depended  upon. 
Carbolic  acid  is  apparently  coming  into  many  new  uses  ;  among 
others  the  strong  acid  is  being  extensively  used  both  in  this  coun- 
try as  well  as  in  Europe,  for  washing  or  swabbing  out  infected  or
