In reference to some remarks in our notice of ' Gatherings of 

 a Naturalist in Australasia' {' Ibis/ vol. iii. p. 197), Dr. Bennett 

 writes to us from Sydney (Aug. 20, 1861) as follows : — 



" You mention in the review (in 'The Ibis') of my ' Gather- 

 ings,' that the diagram of the Albatros is not explained. In 

 this I agree with you, and send you the following explanation. 

 The diagram forms the segment of a circle : — N. is the direction 

 from which the wind is supposed to be blowing ; c. is a ship 

 sailing within six points of the wind ; b. is the course of a cutter 

 which can sail, ' close-hauled/ to within four and a half points of 

 the wind ; a. is the course of the Albatros, which flies so close to 

 the wind as to keep to within two points of the wind, and appears 

 almost to fly against it." 



Dr. Bennett also states that he has great hopes of being able 

 to procure living specimens of the Kagu [RMnochetus jubatus*) 

 of New Caledonia for the Zoological Society of London, of whose 

 Menagerie he has already been so distinguished a benefactor. 



Mr. T. C. Jerdon, so well known for his writings on Indian 

 Natural History, has in an advanced state of preparation a 

 work on the Natural History of the Vertebrated Animals of that 

 country. It will contain characters of all the classes, orders, 

 families, and genera, and descriptions of all the species of Mam- 

 mals, Birds, Beptiles, and Fishes found in India. 



The geographic limits of the animals described in this work 

 will be : — on the north, the watershed of the Himalayas ; 

 thence, on the east, from Teesta Iliver to its junction with the 

 Bramajiootra, and down that river to the Bay of Bengal ; on the 

 west, from the Indus, where it breaks through the Himalayas, 

 to Kurrachee; and on the south, Cape Comorin. 



The object of this work being to enable naturalists and tra- 

 vellers to identify such objects of natural history as they may
