healing  process.

Poisoning  by  Male  Fern  is  reported  by  Hofmann  (  Wien.  klin.  Wochenschr.) 
in  the  case  of  a  girl  5^  years  old,  who  took  7-5  gm.  oleoresin  of  male  fern  in 
three  doses  within  ij{  hours.  A  portion  of  the  tape  worm  was  expelled  in  1^ 
hours,  then  vomiting  and  somnolence  set  in,  which  after  three  hours,  was  fol- 
lowed by  convulsions  and  death.  The  fatal  result  was  presumably  caused  by 
impaired  resistance  due  to  miliary  tuberculosis  of  the  lungs  and  abdominal 
glands. 
Gelatin  paste,  recommended  by  Unna,  has  been  used  by  Prof.  Trendelen- 
berg  for  flexible  dressing,  permitting  free  motion  of  the  parts,  and  not  inter- 
fering with  the  excretory  functions  of  the  skin.  It  is  prepared  in  two  degrees 
of  consistence  :  The  thick  paste  contains  gelatin,  glycerin  and  water  each  30 
parts,  with  oxide  of  zinc  10  parts.  The  thin  paste  has  gelatin  20  parts,  gly- 
cerin 30  parts,  water  40,  with  oxide  of  zinc  10  parts.  Heat  is  necessary  when 
the  pastes  are  compounded  ;  it  is  also  needed  to  liquefy  them  when  they  are 
used.  The  pastes  are  readily  removed  with  warm  water. — Jour.  Am.  Med.

Monesia  bark  from  Chrysophyllum  glyciphlseum,  Casaretti,  has  been 
studied  by  P.  G.  Rozanoff  (Inaug.  Dissert.  Moscow,  1890),  who  considers  it  to 
be  a  very  good  expectorant,  due  to  the  presence  of  saponin  and  monesin  ; 
abounding  in  tannin,  the  bark  possesses  also  valuable  astringent  properties.
