It  is  not  easy  to  find  or  frame  a  specific  name  which  will  clearly 
express  the  most  remarkable  characteristic  of  this  new  species.  But 
I  will  venture  to  name  it 
Erythronium  propullans. — E.  scapo  infra  folia  pullulante  ;  foliis 
oblongo-lanceolatis  acuminatis  parum  maculatis  ;  perianthio  roseo- 
purpureo  (semipoilicari),  segmentis  acutis  basi  luteo  tinctis  omnino 
planis  (nec  calloso-dentatis  nec  sulcatis) ;  antheris  oblongis;  stylo  fere 
equabili  integerrimo ;  stigmate  parvo  vix  tridentato ;  ovulis  in  locu-

Scape  bulbiferous  from  its  sheathed  portion  below  the  developed 
leaves;  these  oblong-lanceolate,  acuminate,  slightly  mottled ;  perianth 
rose-purple  or  pink  (half  an  inch  long) ;  the  segments  acute,  all  with 
a  yellow  spot  but  plane  at  the  base,  the  inner  like  the  outer  destitute 
of  either  groove  or  tooth-like  appendages,  but  a  litle  more  narrowed 
at  base  ;  anthers  merely  oblong ;  style  hardly  at  all  narrowed  down-

ON  A  RARE  FORM  OF  POISONING  BY  QUININE. 
By  a.  Brayton  Ball,  M.  D. 
The  more  common  symptoms  of  quinism,  such  as  headache,  tinnitus 
aurium,  vomiting,  prostration,  etc.,  are  familiar  to  every  physician, 
but  the  occurrence  of  an  erythematous  rash,  accompanied  by  oedema, 
and  extending  over  the  whole  body,  followed  by  desquamation,  is  so 
rarely  a  toxic  effect  of  quinine  that  I  have  not  found  any  mention  of 
it  by  such  systematic  writers  on  materia  medica  as  Headland,  Wood, 
Stille,  Beck,  Biddle,  Waring,  Royle,  Trousseau  and  Pidoux. 
Briquet,  in  his  monograph  on  quinine,*  quotes  Chevallier  as  having 
observed  that  workers  in  quinine  were  liable  to  various  cutaneous 
eruptions ;  but  this  effect  is  ascribed  by  Briquet  to  local  irritation  by 
the  drug.  In  his  numerous  experiments,  the  author  noticed  no  special 
effect  upon  the  skin,  except  a  very  constant  diminution  in  its  tem- 
perature. Rilliet  and  Barthez  record  a  case  of  desquamation,  and 
Bouchut  a  roseola  following  the  use  of  medicinal  doses  of  quinine.
