Ph.D.,  M.D.,  Polytechnic  Society,  Louisville,  Ky.  The  rules  have 
recently  been  republished  by  the  Bureau  of  Education,  and  the  spell- 
ing has  been  adopted  by  several  chemical  journals,  and  it  is  to  be 
hoped  that  the  desired  uniformity  may  be  reached  before  long,  even 
though  certain  modifications  may  become  desirable,  the  committee 
having  been  well  aware  that  these  rules  are  not  to  be  regarded  as 
final. 
GENERAL  PRINCIPLES  OF  PRONUNCIATION. 
(1)  The  pronunciation  is  as  much  in  accord  with  the  analogy  of 
the  English  language  as  possible. 
(2)  Derivatives  retain  as  far  as  possible  the  accent  and  pronuncia- 
tion of  the  root  word. 
(3)  Distinctly  chemical  compound  words  retain  the  accent  and 
pronunciation  of  each  portion. 
(4)  Similarly  sounding  endings  for  dissimilar  compounds  are 
avoided  (hence  id,  -ite). 
ACCENT. 
In  polysyllabic  chemical  words,  the  accent  is  generally  on  the 
antepenult ;  in  words  where  the  vowel  of  the  penult  is  followed  by 
two  consonants,  and  in  all  words  ending  in  -ic  the  accent  is  on  the 
penult. 
PREFIXES. 
All  prefixes  in  strictly  chemical  words  are  regarded  as  parts  of 
compound  words,  and  retain  their  own  pronunciation  unchanged  (as 
a'ceto-,  a/mido-,  a/zo-,  hy'dro-,  I'so-,  nl'tro,  nitrd'so-). 
ELEMENTS. 
In  words  ending  in  -ium,  the  vowel  of  the  antepenult  is  short  if 
i  (as  iridium),  or  y  (as  didy'mium,  or  if  before  two  consonants  (as 
Fate,  fat,  far,  mete,  met,  pine,  pin,  marine,  note,  not,  move,  tube,  tub,  rule, 
my,  y  =  1. 
'  Primary  accent  ;  "  secondary  accent.  N.  B. — The  accent  follows  the  vowel 
of  the  syllable  upon  which  the  stress  falls,  but  does  not  indicate  the  division 
of  the  word  into  syllables.
