As anuounced in the preface to Ascidia, a donation 

 from Mr. F. H. (iossage, of Wooltoii, met the expense 

 of preparing the plates in illustration of the tirst few 

 Memoirs, and so enabled the Committee to commence 

 the publication of the series sooner than would otherwise 

 have been jjossible. Other donations received since from 

 Mr. Gossage, Mrs. Holt, Sir -lohn Brunner, and others, 

 are regarded by the Committee as a welcome encourage- 

 ment, and have been a great help in carrying on the work.
