up to Polyandria had been gone over and added to ; 

 and he alluded to the fact of his having published a 

 Visitor s Companion to the Botanic Garden. A new 

 species of Verbena^ from South America, had been raised 

 from seed collected by Mr. John Tweedie of Buenos 

 Ayres. The stock of what proved to be a very lovely 

 plant raised in it (save one plant) was disposed of for 

 50 guineas, for the benefit of the Garden. 



On the 8th of November 1838, Mr. David Moore, 

 who afterwards became a Ph. Doc., was elected curator in 

 the room of Mr. N. Niven. The title of his post was 

 afterwards changed to that of Director. In 1878, in 

 recognition of his scientific eminence, Dr. Moore was 

 elected an honorary member of the Royal Dublin Society.

 to him, and, on his death in 1879, left the Garden 

 in a high state of efficiency. His son, Sir Frederick W.

 was knighted in 1911), succeeded him. Under Dr. 

 Moore's regime, all the old houses, except the octa-

 iron conservatories was built in 1843, at a cost f over 

 ^5000, of which sum 4000 were contributed by 

 Government, the balance being paid by the Royal 

 Dublin Society. Part of this balance was raised by 

 private subscription among the members, and part was 

 taken from the Society's reserve fund. The designs of 

 these houses were furnished by Mr. Ferguson, master 

 of architectural drawing in the School of Art, and by 

 Mr. Frederick Darley. The first palmhouse, com- 

 pleted in 1862, was from a design of Mr. James H. 

 Owen, architect of the Board of Works. This, being 

 injured by the gales of 1833, was removed, and a 

 splendid new one was erected in the next year. The
