 genial kindliness, Dr. Fripp was, not without much hesitation 

 on his part, elected a Member of the Council at the annual 

 meeting in May, 1868, and one of the Vice-Presidents in 

 1871. On the death of Mr. Wm. Sanders he was elected 

 to the Presidential chair, which he most honourably occu- 

 pied till he was suddenly taken from among us on March 

 23rd, 1880.
