QUERIES. 
(1)  Sanguinaria. — The  liquid  preparations  slowly  deposit  a  precipitate  upon 
the  sides  of  the  containers.  Can  a  menstruum  be  devised  which  will  hold  per- 
manently in  solution  the  soluble  constituents  ? 
(2)  Gelatine  Capsules. — What  general  rule  should  be  adopted  in  compound- 
ing prescriptions  ordering  gelatine  capsules  ?  When  should  the  ingredients  be 
dispensed  in  dry  powder,  and  when  is  it  preferable  to  form  them  into  a  mass  ? 
(3)  Ichthyol. — Ichthyol  is  now  being  used  internally,  dissolved  in  water  and 
other  media.    A  palatable  form  of  administration  is  wanted. 
(4)  Salol  and  Acetanilid  are  given  usually  in  powder  form.  Cannot  formulas 
for  therapeutically  unobjectionable  liquid  preparations  of  the  same  be  devised  ? 
(5)  Salicylic  Acid. — It  has  been  alleged  that  the  synthetical  salicylic  acid 
now  in  the  market  occasionally  shows  the  presence  of  salol.  Is  this  statement 
correct,  and  if  so,  to  what  extent  ? 
(6)  Formalin. — A  40  per  cent,  solution  of  formaldehyde  under  that  name  is 
attracting  much  attention  as  an  autiseptic  ana  deodorizer.  A  good  practical 
formula  for  its  preparation  by  the  retail  pharmacist  is  wanted. 
(7)  Kamala. — It  is  supposed  that  resin  is  the  active  constituent.  Investiga- 
tion recommended.    Is  a  tincture  advisable  ? 
(8)  Pyrethrmn  Carneum,  Pyrethrum  Roseum,  Pyrethrmn  Cinerariczfo- 
lium. — Insect  powder.  Can  it  not  be  used  as  a  medicine  ?  On  what  depend 
their  insecticide  properties  ? 
(9)  Veronica  Officinalis  is  used  largely  as  a  house  remedy  for  pectoral  com- 
plaints and  skin  diseases.  Is  there  any  alkaloid  or  other  active  principle  in 
the  plant  to  warrant  such  use  ? 
(10)  Viscum  Album  {Mistletoe)  is  used  by  practitioners  to  arrest  post- 
partum and  other  uterine  hemorrhages.    Investigation  invited. 
(11)  Pichurim  Beans. — What  are  they?  Various  descriptions  of  their  oils 
are  given  by  different  investigators. 
(12)  Strophanthus  Seeds. — A  determination  of  the  active  principles  in  the 
seeds  of  commerce,  their  nature,  quantity  and  method  of  valuation. 
(13)  Pareira. — Pareira  is  a  valuable  diuretic  and  tonic  drug.  Buxine  has 
been  found  in  it,  but  this  can  hardly  be  the  important  principle.    What  is  it  ? 
(14)  Rhus. — What  is  the  really  potent  principle  of  the  Rhus  group  ?  Is  it  a 
volatile  acid,  as  claimed  by  Maisch,  oris  it  a  substance  resembling  cardol? 
(15)  Tannin. — At  what  season  of  the  year  should  the  tannin  drugs  be  gath- 
ered ?  What  relation  does  the  amount  of  tannin  present  bear  to  that  of  starch  ? 
Does  the  tannin  increase  as  the  starch  decreases  ?  Or,  is  this  true  of  some  drugs 
but  not  of  others  ? 
(16)  Cypripedium. — There  appears  to  be  a  poisonous  principle,  producing 
effects  similar  to  those  of  Rhus  toxicodendron,  in  the  glandular  hairs  of  some 
cypripediums,  particularly  C.  spectabile.    What  is  this  principle  ?
