reserved  for  compounds  supposed  to  contain  water  of  combination  or  crystallization. 
Compounds  such  as  C'HyONa,  t'oHsONa,  C^HisONa,  etc.,  should  be  termed  sodium  meth- 
■oxide,  etboxide,  heptyoxide,  etc. 
3.  Applj^  the  term  acid  only  to  compounds  of  hydrogen  with  negative  radicles, 
such  as  HNO3,  H.2SO4,  H3PO4,  and  denote  the  oxides  which  form  acids  by  names  such  as 
sulphuric  anhydride  or  sulphur  trioxide.  Term  salts  containing  an  amount  of  metal 
equivalent  to  the  displaceable  hydrogen  of  the  acid,  normal  and  not  neutral  salts,  and 
assign  names  such  as  hydrogen-sodium  sulphate,  liydrogen-disodium  plio.sphate,  etc., 
to  the  acid  salts.   Basic  salts  are  as  a  rule  best  designated  merely  by  their  formulce. 
4.  Use  names  such  as  methane,  ethane,  etc.,  for  the  normal  paraffins  or  hydrocarbons 
of  the  CiiH2n_|^2  series  of  the  form  CH3,(CH2)5.CH3.  The  isomeric  hydrocarbons  are  usu- 
ally most  conveniently  represented  by  names  indicating  their  relation  to  methane;  for 
example,  CHa.CHo.CHo.CHs  =  pi'opylmethane ;  CH3CH(CH3)2  =  isopropylmethane;  or, 
although  less  frequently,  by  names  such  as  diisopropj^l. 
5.  Term  the  liydrocarbons  C!oH4  and  CoHo  ethylene  and  acetylene  respectively  (not 
ethene  and  ethine.  Distinguish  the  homologues  of  ethylene,  whenever  possible,  by 
names  indicating  their  relation  to  it,  sucli  as  methylethylene,  dimethylethylene,  etc., 
denoting  the  di-derivatives  of  the  form  CnH2n_(_i_HC':CH.CiiH2n -^2  a-,  and  those  of 
the  form  CH2:C(CnH2n_|-i)2  as  /J-  compounds;  thus,  CHa.CHiCH.CHg  =^  a-dimetliylethy- 
lene;  CHo.iCKCHa).,  = /^-dimethylethylene.  Similarly,  use  names  such  as  methylacety- 
lene  and  dimethylacetylene  for  the  homologuesof  acetyleneof  the  form  CH  •  C^-Ci^^ti^-I 
and  CnH2n+i.C  •  C.CnH2n+i.  Adopt  the  name  allene  for  the  hydrocarbon  CHo:  C  :  CH2, 
and  indicate  the  relation  which  its  honiologues  bear  to  it  in  the  same  manner  as 
pointed  out  for  acetylene. 
6.  Distinguish  all  alcoliols,  i.e.,  hydroxyl-derivatives  of  hydrocarbons,  bynames 
ending  in  o^,  <?.£;.,  quinol,  catechol,  resorcinol,  saligenol,  glycerol,  erythrol,  mannitol, 
instead  of  hydroquinone,  pyrocatechin,  resorcin,  saligenin,  glycerin,  erythrite,  mau- 
nite.  Compounds  which  are  not  alcohols,  but  which  are  at  present  distinguished  by 
names  ending  in  ol,  may  be  represented-  by  names  ending  in  die,  if  a  systematic  name 
cannot  be  given.  For  example,  write  indole  instead  of  indol ;  furfuraldehyde  instead 
of  furfurol;  fucusaldehyde  instead  of  fucusol.  Ethers  derived  from  phenols,  such  as 
CCH5.OCH3,  etc.,  hitherto  called  anisol,  anethol,  etc.,  may  be  distinguished  bynames 
ending  in  oU,  as  anisoil  and  anethoil. 
Alcohols  should  be  spoken  of  as  mono-,  di-,  tri-,  or  n-hydric,  according  to  the  num- 
ber of  OH  groups. 
7.  Bodies  such  as  the  acids  of  the  lactic  series  containing  the  group  (OH)  should  be 
termed /i2/<^^'0-^^-,  and  not  oxy-derivatives,  e.  g-.,  hydroxyacetic  and  not  oxyacetic  acid. 
Compounds  containing  the  analogous  groups  C2H5O,  C0H5O,  CH3.COO,  etc.,  should  in 
like  manner  be  termed  ethoxy-,  phenoxy-,  acetoxy-  derivatives.  Thus  ethoxypropi- 
onic  acid  instead  of  ethyllactic  acid;  3  :  4  diethoxybenzoic  acid  instead  of  diethylproto- 
<-atechuic  acid;  and  acetoxypropionic  acid  instead  of  acetyllactic  acid.  Terms  such  as 
(liethylprotocatechuic  acid  should  be  understood  to  mean  a  compound  formed  by  the 
displacement  of  hydrogen-atoms  in  the  hydrocarbon  radicle  of  protocatechuic  acid  by 
ethyl,  viz.,  CoH(CoH5)o(OH)2.COOH,  and  not  C6H3(OC2H5)2.COOH,  just  as  dibromoproto- 
catechuic  acid  is  understood  to  be  the  name  of  a  compound  of  tlie  formula 
C6HBr2(OH)2.COOH. 
8.  The  term  ether  should  be  restricted  to  the  oxides  of  hydrocarbon  radicles,  and  the 
so-called  compound  ethers  should  be  represented  by  names  similar  to  those  given  to 
the  analogously  constituted  metallic  salts. 
9.  Compounds  of  the  radicle  8O3H  should,  whenever  possible,  be  termed  sulphonic 
acids,  or,  failing  this,  suipho-compo^mds :  as  ])enzenesulphonic  acid,  sulphf)benzoic  acid, 
and  ]iot  sulfi-compounds.  Compounds  of  the  radicle  SO2.NH0,  should  be  termed  sul- 
phonamides. 
10.  Basic  substances  should  invariably  be  indicated  by  names  ending  in  ine,  as  ani- 
line, instead  of  anilin,  the  termination  in  being  restricted  to  certain  neutral  com- 
pounds, viz.,  glycerides,  glucosides,  bitter  principles  and  proteids,  e.  g.,  palmitin, 
'amygdalin,  albumin.  The  compounds  of  basic  substances  with  hydrogen  chloride, 
bromide  or  iodide,  should  always  receive  names  ending  in  ide  and  not  ate,  as  morphine 
iij  ilrorhloride  and  not  morphine  hydrochlorate,  »
