Pharmacopoea  Norvegica.    Editio  altera.    Regia  aucloritate  edita.  Chris- 
tianiae,  1870.    lmpensis  Alb.  Oamrnermeyer. 
The  former  Norwegian  Pharmacopoeia  was  issued  in  1854,  and  contained  687 
medicaments,  of  which  number  250  have  been  omitted  and  about  60  introduced 
in  the  present  edition,  the  dropped  formulas  being  mostly  of  antiquated  phar- 
maceutical preparations.  The  Committee  of  Revision,  consisting  of  two  physi- 
cians (Drs.  Lochmann  and  Lund)  and  two  pharmacists  (Messrs.  Moller  and 
Huoslef),  has  been  engaged  on  this  work  fully  three  years,  and  has  produced  a 
pharmacopoeia  comparing  favorably  with  other  modern  ones. 
The  Pharmacopoeia  is  printed  in  the  Latin  language,  the  introductory  chap- 
ter containing  the  general  rules  and  directions,  and  being  followed  by  crude 
drugs,  chemical  and  pharmaceutical  preparations,  in  one  alphabetical  arrange- 
ment. To  the  text  quite  a  number  of  tables  are  added,  namely:  List  of  re- 
agents and  test  liquids;  Table  comparing  the  medicinal  with  the  metrical 
weight,  approximately  and  accurately  (lb.  j  =  ^xij  ==  grm.  360  [approx.]  = 
grm.  357  8452  [accurate]);  Table  comparing  the  metrical  with  the  medicinal 
weight;  List  of  very  poisonous  articles,  marked  ff  and  with  red  letters,  to  be 
kept  in  a  locked  closet  (veiatria,  morphia,  strychnia,  atropia,  arsenic,  hydrocy- 
anic acid,  white  precipitate,  corrosive  sublimate,  oxide  of  mercury,  and  all  pre- 
parations containing  the  same)  ;  List  of  poisonous  articles,  marked  f  and  with 
red  letters,  to  be  enclosed  in  tin  boxes  or  vessels  (mostly  narcotic  drugs  and 
their  pharmaceutical  preparations,  salts  of  zinc,  lead,  copper,  antimony,  &c.)  \ 
Table  of  the  maximum  doses  for  adults  of  powerful  medicines  (when  larger 
doses  are  prescribed  the  apothecary  must  consult  the  physician  before  dispens- 
ing); Six  tables  of  the  specific  gravity  and  strength  of  alcohol,  ammonia, 
acetic,  hydrochloric,  nitric  and  sulphuric  acid  ;  Table  of  solubility  of  various 
chemicals  in  cold  water;  Table  of  the  atomic  weight  of  elements,  the  com- 
pounds of  which  are  used  in  medicine;  Table  of  changes  of  names  and  strength 
of  medicines  from  those  of  the  former  pharmacopoeia. 
The  Pharmacopoeia  recognizes  three  degrees  of  the  fineness  of  powders: 
pulvis  crassus,  the  meshes  being  1*5  mm.  in  diameter;  pulvis  communis,  1000 
meshes  to  the  square  cm.;  pulvis  subtilissimus,  2500  meshes  to  the  square  cm. 
The  sieves,  therefore,  are  to  have  about  16,  70  and  120  meshes  to  the  linear 
inch.  Species,  unless  otherwise  ordered,  are  to  be  passed  through  a  No.  6  sieve 
(diameter  of  meshes,  4-5  mm.)  Maceration  is  to  be  effected  at  a  temperature 
of  15  to  25°  C.  (59  to  77°  F  ) ;  digestion  at  35  to  40°  O.  (95  to  101°  F.)  Unless 
other  proportions  are  ordered,  12  grm.  of  plaster  are  used  in  spreading  of  the 
size  of  100  square  cm.,  except  adhesive  plaster,  of  which  2  grm.,  and  empL 
canthar.  colatum,  of  which  10  grm.  are  used. 
]f  a  prescription  for  pills  is  incomplete,  the  pharmacist  uses  water,  syrup, 
alcohol,  glycerin  or  powdered  althea  to  form  the  mass,  which  is  divided  so  that 
each  pill  contains  0T  grin,  of  the  articles  prescribed  :  the  pills  to  be  rolled  in 
lycopodium.    These  additions  are  to  be  noted  on  the  prescription. 
In  dispensing  medicines  for  internal  use,  the  directions  are  written  upon
