﻿ANNIVERSARY 
  ADDRESS 
  OF 
  THE 
  PRESIDENT. 
  49 
  

  

  Everard 
  Home, 
  whose 
  knowledge 
  of 
  crystallography 
  enabled 
  him 
  to 
  

   impart 
  much 
  valuable 
  information 
  to 
  Tennant. 
  

  

  Soon 
  after 
  the 
  opening 
  of 
  King's 
  College 
  the 
  Council 
  desired 
  a 
  

   teacher 
  in 
  mineralogy, 
  and 
  applied 
  to 
  Faraday 
  for 
  his 
  nomination 
  

   of 
  a 
  fit 
  person 
  ; 
  his 
  recommendation 
  was 
  in 
  favour 
  of 
  Tennant, 
  who 
  

   shortly 
  after 
  his 
  appointment 
  received 
  the 
  title 
  of 
  " 
  Professor 
  of 
  

   Mineralogy." 
  This 
  new 
  position 
  opened 
  a 
  wider 
  field 
  of 
  usefulness 
  

   and 
  study. 
  Soon 
  after, 
  Mr. 
  Tennant 
  was 
  appointed 
  Lecturer 
  on 
  

   Mineralogy 
  and 
  Geology 
  at 
  Woolwich, 
  a 
  position 
  which 
  he 
  retained 
  

   until 
  the 
  lectures 
  were 
  discontinued. 
  

  

  Professor 
  Tennant 
  was 
  one 
  of 
  the 
  first 
  to 
  promote 
  the 
  discovery 
  

   of 
  diamonds 
  in 
  South 
  Africa, 
  always 
  believing 
  in 
  their 
  occurrence 
  

   and 
  genuineness. 
  He 
  was 
  an 
  ardent 
  advocate 
  of 
  technical 
  educa- 
  

   tion 
  ; 
  and 
  having 
  seen 
  the 
  valuable 
  application 
  of 
  the 
  lathe 
  in 
  

   cutting 
  both 
  diamonds 
  and 
  other 
  valuable 
  stones 
  and 
  marbles, 
  he 
  

   induced 
  the 
  Turners' 
  Company 
  to 
  promote 
  the 
  advancement 
  of 
  

   turning 
  by 
  offering 
  prizes 
  annually 
  for 
  specimens 
  in 
  all 
  branches 
  

   of 
  the 
  art. 
  Great 
  credit 
  is 
  due 
  to 
  Professor 
  Tennant 
  for 
  the 
  

   revival 
  of 
  this 
  branch 
  of 
  technical 
  education 
  as 
  applied 
  to 
  orna- 
  

   mental 
  work 
  of 
  all 
  kinds 
  and 
  materials. 
  Prof. 
  Tennant 
  was 
  one 
  of 
  

   the 
  founders 
  of

  Association, 
  of 
  which 
  body 
  he 
  was 
  

   formerly 
  President. 
  He 
  was 
  elected 
  a 
  Pellow 
  of 
  this

  belonging 
  

   to 
  the

  whose 
  confidence 
  he 
  enjoyed 
  for 
  

   many 
  years.

  dia- 
  

   mond;

  was 
  a 
  liberal 
  subscriber 
  to 
  many 
  projects 
  for 
  the 
  spread 
  

   of 
  education, 
  but 
  unobtrusively 
  so, 
  many 
  of 
  his 
  personal 
  friends 
  

   only 
  becoming 
  aware 
  of 
  the 
  extent 
  to 
  which

   after
