   of 
  the 
  study 
  of 
  a 
  number 
  of 
  minerals 
  from 
  Madagascar 
  and 
  

   the 
  Ural 
  Mts. 
  Their 
  crystals 
  are 
  figured 
  and 
  described, 
  their 
  

   optical 
  constants 
  and 
  in 
  a 
  number 
  of 
  cases 
  chemical 
  analyses 
  

   are 
  given. 
  The 
  list 
  of 
  Madagascar 
  minerals 
  is 
  as 
  follows: 
  

   from 
  Ambatafotsikely, 
  quartz, 
  muscovite, 
  monazite, 
  columbite, 
  

   euxenite, 
  ampangabeite, 
  struverite, 
  hematite, 
  spessartite 
  ; 
  from 
  

   Ambositra, 
  zircon 
  ; 
  from 
  Amampatsakana, 
  mica 
  ; 
  from 
  Antson- 
  

   gombato, 
  tourmaline 
  and 
  apatite. 
  The 
  following 
  minerals 
  from 
  

   the 
  Urals 
  Mts. 
  were 
  described: 
  from 
  Tokowaia, 
  brookite, 
  topaz, 
  

   spessartite, 
  hematite, 
  rutile, 
  quartz; 
  from

  the 
  ampbiboles 
  

   in 
  the 
  diorite
