 March, 1838. On the 15th March, 1845, he was chosen Treasurer, and 

 continued to hold that office up to the period of his death.

 in the suggestions and remarks that he threw out on the various subjects 

 that came under the notice of the Academy. Among his communications 

 may be mentioned those —

Dr. Ball was elected a Life Member of the Royal Dublin Society in 

 1 834 ; but did not regularly take any active part in its proceedings. In 

 1 854 he became a Member of Council. His co-operation, at all times,
