elementary  or  empirical  formulas  of  the  various  chemical  compounds.  On  the  con- 
trary, it  aims  at  producing  a  general  mathematical  formula  for  all  compounds,  from 
which  the  rational  formula  of  any  compound  may  be  deduced,  bearing  in  mind  the 
different  quantivalence  of  the  elements  or  groups  of  elements  entering  into  combi- 
nation. The  subject  is  one  of  especial  interest  and  importance  in  theoretical  chem- 
istry, and  has  been  treated  in  a  very  commendable  manner.  It  is  impossible,  how- 
ever, in  the  brief  space  allotted  to  this  review  to  follow  the  author  in  his  evolution 
of  the  generalized  formula,  and  to  give  the  latter  without  the  preceding  considera- 
tions would  be  of  no  avail. 
In  an  appendix,  the  author  has  arranged  a  number  of  formulas  regarding  all 
elements  as  being  of  the  same  chemical  value  (univalent),  but  reserves  for  future 
consideration  to  determine  the  general  applicability  of  such  a  theory.  There  is  no 
difficulty  in  the  way  of  this  view  as  long  as  the  compounds  consist  of  one  atom  each 
of  two  elements  ;  but  with  a  larger  number  of  one  or  both  it  is  different,  and  we 
believe  it  will  be  of  interest  to  our  readers  to  learn,  from  a  few  examples,  the  shape 
which  the  formulas  of  some  well  known  compounds  would  assume.  Water,  H20= 
(0/ — H/)/H/5  oxide  of  potassium,  K20  =  (0/ — K/)/K/j  hydrate  of  sodium 
NaHO  =  (O'— Na/)/H/j  ammonia,  NH3  =  [(N/ — H/)/ — H/]/H/  ;  acetylene,

Proceedings  of  the  Connecticut  Pharmaceutical  Association  at  the  Second  Annual  Meet- 
ing, held  in  New  Haven,  Conn.,  Feb.  6th,  1878.  New  Haven.  Pp.  43. 
The  meeting  was  opened  by  the  President,  Nathan  Dikeman.  The  reports  of 
officers  and  committees  were  presented  and  the  usual  routine  business  transacted. 
The  draft  of  a  proposed  pharmacy  act  was  submitted,  discussed  and  adopted,  and  a 
committee  appointed  to  present  it  to  the  Legislature  and  urge  its  passage.  Nine 
papers  on  practical  subjects  and  affairs  of  the  Association  were  read  and  referred  for 
publication.  The  following  officers  were  elected  to  serve  for  the  current  year  : 
President,  Hugh  H.  Osgood,  Norwich  5  Vice  Presidents,  Dwight  Phelps,  West 
Winsted,  and  F.  V.  Perry,  Danbury  5  Secretary,  Romanta  Wells,  New  Haven  ; 
Treasurer,  George  P.  Chandler,  Hartford. 
Eighth  Annual  Report  of  the  State  Board  of  Pharmacy,  made  to  the  General  Assembly 
1878.    Providence,  R.  I." 
During  the  past  year  fourteen  persons  applied  for  registration  as  pharmacists,  ten 
of  whom  passed  on  the  first,  three  on  the  second  and  one  on  the  fourth  examina- 
tion. Of  six  applicants  for  registration  as  assistants  three  passed  on  the  first  and  one 
on  the  second  examination.

Third  Annual  Report  of  the  Alumni  Association  of  the  St.  Louis  College  of  Pharmacy.

The  organizations  whose  reports  are  before  us  have  the  praiseworthy  object  to 
unite  the  graduates  into  closer  fellowship,  and  to  advance  the  interests  of  the  institu- 
tions where  the  graduates  have  received  their  pharmaceutical  honors.  Local  in 
character,  such  associations  nevertheless  exert  a  laudable  influence  in  more  distant 
localities  by  promoting  good  feeling  among  its  members  wherever  they  may  reside, 
and  by  renewing  through  these  annual  publications  the  bond  of  union  which  naturally 
centers  in  the  Alma  Mater.  The  graduates  of  the  different  colleges  of  pharmacy, 
whose  only  object  has  not  been  to  obtain  the  coveted  degree,  attach  themselves  to 
an  association  the  ultimate  aim  of  which,  obviously,  is  the  promotion  of  pharma- 
ceutical education  and  pharmaceutical  progress.
