made,  were  found  to  increase  bleeding  on  local  application;  cotar- 
nine  salts  (stypticin  and  styptol),  antipyrin,  peptone,  emetine,  some- 
times alum,  orthoform.  (i  per  cent,  solution)  also  quite  markedly 
increased  local  bleeding.  Under  the  conditions  kephalin,  coagulen, 
and  thromboplastin  were  all  variable,  or  did  not  affect  the  course  of 
bleeding.  (P.  J.  Hanzlik,  Jour.  Pharmacol,  and  Exp.  Ther.,  v.  12,

The  Effects  of  Various  Systemic  Agents  on  Superficial 
Hemorrhage. — The  most  effective  hemostatic  agent  on  superficial 
bleeding  by  systemic  (intravenous)  administration  was  epinephrin; 
tyramin  somewhat  less ;  pituitary  extract  was  variable.  Fatal  doses 
of  ergot  and  digitalis  (one  experiment  each)  also  lessened  and  ar- 
rested, respectively,  the  bleeding.  The  effects  of  the  following  (sys- 
temically)  on  bleeding  are  roughly  parallel  to  the  changes  in  blood 
pressure:  coagulen  (Ciba),  kephalin  (Howell),  thromboplastin 
(Squibb),  horse  serum,  stypticin,  gelatin,  saline,  emetine,  and  possi- 
bly peptone.  Nitrite  and  hydrastis  increased  bleeding  with  a  fall  in 
pressure.  The  results  with  the  thromboplastic  agents  might  be  dif- 
ferent with  prolonged  administration.  (P.  J.  Hanzlik,  Jour.  Phar- 
macol and  Exp.  Ther.,  v.  12,  pp.  1 19-128,  1918.)

Annals  of  the  Missouri  Botanical  Garden,  No.  3,  Vol.  v,  Sep- 
tember, 1918. 
Three  articles  of  general  botanic  interest  appear  in  this  number 
of  the  Annals.  The  first  of  these  is  by  E.  A.  Burt,  mycologist  to 
the  Missouri  Botanical  Garden,  and  is  entitled  "  The  Thelephoraceae 
of  North  America."  The  author  discusses  the  structure  and  dis- 
tribution of  fourteen  species  belonging  to  the  genus  Aleurodiscus 
that  occur  in  North  America.  Accompanying  the  description  of 
each  species  are  valuable  sketches  of  diagnostic  portions  of  the  fruc- 
tifications.   A  key  to  the  identification  of  the  species  is  also  given. 
The  second  article  is  on  "A  New  Selaginella  from  Mexico,"  by 
J.  M.  Greenman  and  Norma  E.  Pfeiffer.  This  species  was  collected 
with  other  plants  in  southern  Mexico  by  Dr.  W.  J.  G.  Land  and  Prof.
