of  an  ox  and  fresh  human  blood,  the  human  blood  will  be  found  to  contain 
the  largest  corpuscles,  and  can  readily  be  recognized  even  on  admixture 
with  ox  blood  corpuscles,  which  are  smaller  ;  but  when  time  has  elapsed, 
and  the  blood  completely  dead  on  the  texture  of  the  cloth,  the  corpus- 
cles become  shrunken,  and  give,  as  regards  their  size,  very  uncertain  re- 
sults. In  the  present  case,  all  the  corpuscles  were  round  (in  the  blood 
taken  from  the  clothes),  and  therefore  belonged  to  one  class,  viz. :  the 
mammalia,  i.  e.,  ox,  dog,  sheep,  cat,  etc.  It  could  not  belong  to  birds  or 
fishes,  as  their  corpuscles  are  oval. 
The  spots  on  the  seat  were  covered  over  with  the  eggs  of  a  fish,  which 
I  scraped  away  and  came  down  to  dark  spots,  which  had  penetrated  the 
wood.  I  took  off  the  particles  of  wood  with  a  clean  sharp  knife  and 
rasped  them  into  a  powder,  and  soaked  this  powder  with  glycerine  for  ten 
hours.  On  putting  a  few  drops  of  the  glycerine  under  the  microscope  I 
found  abundant  evidence  of  blood  corpuscles,  the  round  ones  predomi- 
nating. There  were  also  oval  ones,  which  could  be  either  fish  or  bird 
blood. 
On  the  conclusion  of  this  investigation  I  am  compelled,  though  having* 
experimented  more  or  less  for  six  years  on  the  blood  of  animals,  fowls 
and  fishes,  to  depose  that  when  dried  for  any  length  of  time  and  again 
moistened,  great  difficulty  will  be  experienced  in  attempting  to  fix  its 
origin  by  the  size  of  its  corpuscles.

The  Schools  of  Pharmacy — Session  1866-67. — We  believe  the  coming 
winter  will  be  marked  by  larger  classes  and  more  than  usually  energetic 
progress  in  pharmaceutical  teaching.     The  Philadelphia  College  pro- 
mises to  open  with  a  large  class,  under  favorable  auspices,  and  aided  by 
its  numerous  cabinets  and  the  ability  of  its  Faculty,  we  doubt  not  a  favor- 
able report  to  the  College  in  March  will  be  made.    One  of  the  chief 
difficulties  that  presents  itself  is  to  find  employment  for  the  young  men 
who  come  to  this  city  to  attend  the  lectures  during  the  winter  seaaon.  Two 
motives  urge  them  to  seek  employment :  1st,  to  gain  the  advantages  of 
the  practice  of  pharmacy  as  conducted  in  Philadelphia  ;  and  2d,  a  means 
of  support  during  their  sojourn  at  the  School.    The  New  York  College 
appointed  a  committee  to  aid  in  this  work  of  seeking  employment,  and  the 
effort  might  well  be  imitated  here,  as  subsidiary  to  the  advancement  of  our 
School  of  Pharmacy.    We  believe  our  Faculty  don't  do  justice  to  the 
School  in  the  matter  of  an  annual  prospectus.    The  brief  notice  which 
heretofore  has  been  issued  is  entirely  too  modest  to  accord  with  the  re- 
ceived usage  of  the  Schools  and  the  expectations  of  applicants.    We  are 
constantly  written  to  for  information  in  this  form,  and  are  compelled  to 
send  only  this  programme,  or  submit  to  the  inconvenience  of  writing  out 
a  sheet  full  of  answers  to  legitimate  queries.     We  have  in  pamphlet  form 
a  prospectus  from  the  New  York  College,  of  ten  pages,  and  another  from 
the  St.  Louis  College,  of  fourteen  pages,  setting  forth  the  merits  of  their 
several  Schools.     In  both  Schools  botany  is  considered  one  of  the  branches 
taught,  and  at  St.  Louis  it  is  conducted  on  a  scale  as  a  summer  course  not 
elsewhere  reached  among  our  Pharmaceutical  Colleges.    This  branch,  so
