NOTICE. 



In publishing- the completion of the Second Volume, the Editor again 

 thanks his friends for their support, and again apologizes for all delays. 

 Any considerable increase in the former will be followed by a de- 

 crease in the latter. 



Many of the Subscribers are already aware that the Editor's father, 

 Mr. G. B. Sowerby, F.L.S., to whom they are indebted for several 

 Monographs, has been removed by death, after a life devoted to 

 Science. His family, his acquaintances, his commercial patrons, and 

 his fellow labourers in Natural History, will ever remember him with 

 affection and honour, as a husband, a father, a friend, a man of inte- 

 grity, and a useful contributor to knowledge. 



The business at 70, Great EusscU Street, is continued by a part of 

 the family.
