jars  and  glittering  lables  for  their  products.  Samples  of  cosmolin  are  freely 
distributed  to  visitors. 
Morehouse,  Rockefeller  &  Co.  have  done  their  utmost  to  present  samples  of 
twenty-seven  varieties  of  lubricating  oils  in  a  highly  attractive  manner.  They 
deserve  credit  for  the  ingenuity  of  the  arrangement,  which  consists  of  very 
long  glass  cylinders,  of  graduated  sizes,  enclosed  on  top  and  below  in  walnut. 
Perfumery  is  exhibited,  in  great  variety,  by  Hermann  A.  Yogelbach,  Wm. 
M.  Wilson  &  Co.,  Samuel  Campbell,  A.  Fricke  and  S.  C.  Upham.  The  three 
first-named  welcome  all  visitors  most  cordially  with  the  perfume-diffusing 
atomizers.    Mr.  Vogelbach's  American  extracts  meet  with  much  favor. 
McKeone  &  Van  Haagen  have  a  large  assortment  of  fancy  toilet  soaps  on 
exhibition.  We  were  pleased  most  by  their  white  Castile  soap,  made  by  them- 
selves from  pure  olive  oil,  and  quite  equal  in  quality  to  the  best  imported. 
The  Dempsey  Wicker  Covered  Glassware  Company  present  their  demijohns 
and  covered  bottles,  furnished  with  glass  and  tin  labels.  These  possess  some 
obvious  practical  advantages,  and  they  appear  to  be  gaining  popularity. 
Perfumers'  and  druggists'  glassware  is  exhibited  in  profusion  by  Whitall, 
Tatum  &  Co.  and  the  New  England  Glass  Company. 
Jas.  K.  Kerr  &  Bros,  have  a  workman  at  the  Exhibition  employed  in  the 
interesting  process  of  engraving  on  glass.  They  employ  for  this  purpose 
American  corundum  from  the  Unionville  mine,  of  Chester  County,  which  they 
state  to  be  superior  to  the  imported  emery.  Specimens  of  native  and  prepared 
corundum  are  exhibited  in  another  portion  of  the  building. 
Hale  &  Manley  make  a  handsome  display  of  labels  and  signs. 
William  Holzer  exhibits  glass  syringes,  pipettes,  glass  models  of  apparatus, 
and  other  chemical  glassware  ;  also,  a  mammoth  alcohol  thermometer,  twelve 
feet  high.  His  workmen  are  constantly  employed  in  blowing  fancy  toys  of 
colored  glass,  before  a  throng  of  admirers,  to  whom  they  distribute  a  facetious 
circular,  which  dilates  upon  the  virtues  of  the  chemical  hand-glass,  by  a  dubious 
euphemism  styled  "  the  sympathy  thermometer,  or  philosophic  love-tester." 
Barrows,  Savery  &  Co.  offer  china-lined  cluster  pots  in  halves,  thirds  and 
quarters,  affording  facilities  for  heating  either  two,  three  or  four  different  liquids 
on  one  fire.  Although  intended  chiefly  for  household  purposes,  they  may 
occasionally  prove  quite  serviceable  to  pharmacists. 
Richard  C.  Remmey  exhibits  some  fine  specimens  of  chemical  stoneware. 
N.  M.  Kerr  &  Co.  display  a  case  of  choice  paper  boxes,  some  of  them  of 
novel  construction,  and  rivalling  the  finest  imported  in  elegance. 
Joseph  Zentmayer,  the  renowned  optician,  exhibits  a  case  containing  nine 
beautiful  microscopes,  of  various  powers.  These  have  been  specially  made  by 
him  for  the  philosophical  cabinet  of  the  University  of  Pennsylvania. 
Optical  and  philosophical  instruments  are  also  displayed  in  great  profusion 
by  James  W.  Queen  &  Co.,  Wm.  Y.  McAllister  and  Heller  &  Brightley. 
Dr.  W.  H.  Pile  exhibits  a  selection  of  his  well-known  hydrometers,  specific 
gravity  bottles  and  aluminium  weights. 
Druggists'  scales  and  analytical  balances,  of  very  fine  workmanship,  are 
shown  by  H.  Troemner  and  Becker  &  Sons.
