  cells 
  containing 
  a 
  nucleus. 
  The 
  fresh 
  yeast 
  consists 
  of 
  

   these 
  individual 
  cells 
  ; 
  but 
  after 
  being 
  mixed 
  with 
  the 
  

   wort 
  of 
  beer 
  for 
  an 
  hour, 
  budding 
  will 
  

   have 
  commenced 
  (as 
  in 
  fig. 
  g). 
  These 
  

   buds 
  will 
  ultimately 
  increase 
  to 
  the 
  size 
  

   of 
  the 
  parent 
  cells, 
  and 
  these 
  will 
  again 
  

   bud 
  ; 
  so 
  that 
  in 
  six 
  or 
  eight 
  hours 
  a 
  

   string 
  of 
  cells 
  will 
  be 
  found 
  to 
  have 
  been 
  

   produced, 
  attached 
  to 
  each 
  other 
  like 
  a 
  

   strin^ 
  of 
  beads, 
  with 
  occasional 
  lateral 
  branches. 
  Some 
  

   authors 
  have 
  referred 
  the 
  yeast-plant 
  to 
  a 
  low 
  station 
  

   in 
  a 
  subdivision 
  of 
  A 
  Igce. 
  

  

  The 
  vinegar-plant 
  is 
  of 
  a 
  similar 
  nature, 
  and 
  both 
  

   are 
  more 
  correctly 
  included 
  amongst 
  those 
  plants 
  with 
  

   which 
  we 
  have 
  associated 
  them. 
  This 
  view 
  is 
  supported 
  

   by 
  the 
  most 
  eminent 
  mycologists 
  of 
  the 
  present 
  day. 
  

  

  MUCORACEOUS 
  FUNGI. 
  

   The 
  fifth 
  group 
  or 
  family, 
  the 
  Physomycetes, 
  is 
  a 
  

   small 
  one, 
  at 
  least 
  so 
  far 
  as 
  British 
  examples 
  are 
  con- 
  

   cerned, 
  and 
  forms 
  an 
  intermediate 
  link 
  between 
  the 
  

   Sjyoriferous, 
  or 
  naked-spored 
  fungi, 
  and 
  the 
  Sporidiife- 
  

   rous, 
  or 
  those 
  in 
  which 
  the 
  spores 
  are 
  inclosed, 
  to 
  which 
  

   this 
  group 
  belongs. 
  In 
  the 
  Phrfsomycetes, 
  the 
  cells 
  

   which 
  contain 
  the 
  spores 
  are 
  bladder 
  -shaped, 
  and 
  

   scattered 
  upon 
  threads, 
  which 
  are 
  not 
  compacted 
  into 
  a 
  

   distinct 
  hymeiiiuin. 
  Like 
  the 
  true 
  moulds, 
  these 
  

   minute 
  plants 
  are 
  found 
  upon 
  decaying 
  vegetable 
  sub- 
  

   stances, 
  especially 
  articles 
  of 
  food. 
  The 
  bread-mould 
  

   is 
  a 
  common 
  and 
  familiar 
  example, 
  and 
  if, 
  in 
  this
