  probably 
  the 
  best 
  of 
  all 
  in 
  and 
  around 
  Vienna, 
  although 
  not 
  yet 
  

   accessible 
  by 
  sinkings. 
  Their 
  regions 
  of 
  infiltration 
  lie 
  between 
  

   16,800 
  and 
  21,600 
  feet 
  west 
  of 
  the 
  well 
  in 
  the 
  " 
  Getreide-Markt," 
  

   at 
  a 
  height 
  of 
  between 
  600 
  and 
  840 
  feet. 
  In 
  the 
  middle 
  or 
  brackish 
  

   formation 
  five 
  water-bearing 
  horizons 
  are 
  at 
  present 
  known, 
  bnt 
  

   the 
  nethermost 
  has 
  not 
  been 
  reached 
  within 
  the 
  precincts 
  of 
  Vienna 
  ; 
  

   its 
  region 
  of 
  infiltration 
  lies 
  from 
  6800 
  to 
  8700 
  feet 
  west 
  of 
  the 
  

   above-mentioned 
  well, 
  at 
  a 
  level 
  of 
  from 
  540 
  to 
  768 
  feet. 
  The 
  

   uppermost 
  (Congerian) 
  strata, 
  probably 
  deposited 
  subsequently 
  to 
  a 
  

   partial 
  destruction 
  of 
  the 
  brackish- 
  water 
  strata, 
  are 
  best 
  known 
  ; 
  the 
  

   water 
  from 
  them 
  is 
  most 
  used 
  for 
  domestic 
  purposes, 
  and 
  comes 
  out 
  

   generally 
  under 
  powerful 
  pressure. 
  Their 
  region 
  of 
  infiltration 
  lies 
  

   from 
  6000 
  to 
  8400 
  feet 
  from 
  the 
  well 
  in 
  the 
  " 
  Getreide-Markt," 
  in 
  

   levels 
  between 
  480 
  and 
  660 
  feet. 
  Two 
  other 
  systems, 
  above 
  those 
  

   just 
  mentioned, 
  only 
  give 
  infiltrated 
  water. 
  One 
  of 
  them, 
  situated 
  

   within 
  the 
  higher 
  regions 
  of 
  the 
  city, 
  derives 
  its 
  water 
  from 
  merely 
  

   local 
  infiltrations 
  through 
  the 
  Belvedere 
  (Diluvial) 
  gravel; 
  it 
  extends 
  

   as 
  far 
  as 
  6000 
  feet 
  westward 
  from 
  the 
  well 
  of 
  the 
  '"Getreide-Markt," 
  

   and 
  reaches 
  a 
  level 
  of 
  from 
  480 
  to 
  690 
  feet. 
  The 
  newest 
  water- 
  

   bearing 
  horizon 
  is 
  that 
  of 
  the 
  Danube 
  ; 
  its 
  water, 
  infiltrating 
  from 
  

   east 
  to 
  west, 
  saturates 
  the 
  loose 
  ground 
  near 
  the 
  " 
  Getreide-Markt," 
  

   at 
  a 
  level 
  of 
  from 
  468 
  to 
  504 
  feet 
  above 
  the 
  sea-level. 
  AVhere 
  it 
  

   meets 
  with 
  the 
  local 
  infiltration-water 
  of 
  the 
  Belvedere 
  gravel 
  (about 
  

   468 
  feet 
  above 
  the 
  sea-level), 
  it 
  occasionally 
  stops 
  the 
  latter, 
  raising 
  

   it 
  to 
  a 
  higher 
  level.

  the

  Many 
  of 
  these 
  remains 
  have 
  lately 
  been 
  found 
  in 
  the 
  " 
  Loess 
  " 
  of 
  

   Nussdorf 
  (north-west 
  of 
  Vienna), 
  in 
  which 
  an 
  extremely 
  large 
  

   skull 
  of 
  Elephas 
  prirnigenius 
  was 
  also 
  discovered. 
  The 
  most 
  abun- 
  

   dant 
  species 
  of 
  these 
  minor 
  forms 
  is 
  the 
  common 
  Mole 
  (Talpa 
  Eu- 
  

   ropcea), 
  whose 
  remains 
  are 
  so 
  completely 
  characterized 
  that 
  there 
  

   can 
  no 
  longer 
  be 
  any 
  doubt 
  about 
  the 
  specific 
  identity 
  of 
  the 
  diluvial 
  

   with 
  the 
  existing 
  form. 
  Of 
  Sorex 
  vulgaris, 
  Linn., 
  var., 
  only 
  one 
  

   specimen 
  has 
  been 
  found 
  — 
  a 
  lower 
  jaw 
  with 
  its 
  teeth 
  complete. 
  It 
  

   indicates 
  a 
  form 
  intermediate 
  between 
  the 
  common 
  Wood-Shrew 
  

   and 
  the 
  Alpine 
  Shrew, 
  differing 
  from 
  Sorex 
  pygmceus 
  by 
  the 
  slight 
  

   sinus 
  between 
  the 
  unbent 
  apex 
  and 
  the 
  first 
  tubercle 
  of 
  the 
  fore 
  

   tooth, 
  and 
  from 
  Sorex 
  alpinus 
  by 
  the 
  single 
  pointed 
  form 
  of 
  the 
  first 
  

   molar. 
  Nevertheless 
  the 
  general 
  aspect 
  of 
  this 
  jaw, 
  especially 
  in 
  

   its 
  coronal 
  process, 
  and 
  in 
  the 
  shortly 
  pointed 
  crooked 
  process, 
  ex- 
  

   tending 
  backward 
  in 
  a 
  straight 
  line, 
  offers 
  a 
  striking 
  resemblance 
  to 
  

   the 
  jaw 
  of 
  Sorex 
  alpinus. 
  The 
  first 
  (pointed) 
  molar, 
  instead 
  of 
  

   having 
  a 
  conical 
  profile, 
  as 
  in 
  Sorex 
  vulgaris, 
  shows 
  a 
  rather 
  length- 
  

   ened 
  and 
  even 
  somewhat 
  sinuated 
  posterior 
  edge 
  ; 
  so 
  as 
  to 
  stand 
  

   intermediate 
  between 
  the 
  normal 
  form 
  and 
  the 
  two-edged 
  molar 
  of 
  

   Sorex 
  alpinus.

  form

  the

  tooth
