1840.] On Low Steam Power to Vessels, instead of Sails. 227 



With this view, I earnestly solicit any of the readers of this Catalogue, 

 (who may have the opportunity and inclination), to forward me 

 any observations they may make, and let them not deem the small- 

 est scrap of information too trifling to send. I would more parti- 

 cularly request further intelligence regarding the nidification of the 

 Indian birds, of which so little is known, their various notes, food, and 

 manner of feeding, times of appearance aud disappearance of migra- 

 tory species, names in any of the native languages, and any tales, 

 proverbs or superstitious ideas the natives may have concerning them. 

 There are also a few desiderata which I shall here enumerate, aud any 

 individuals who may have it in their power to give any information 

 regarding them, will receive my best thanks. 



No 6. — Specimen of the large Fishing Eagle of the Chilka lake, which 

 I suspect may be the Hal. ichthy&tus, No. 8 of the Cat. 



No. 34. — Specimen and descriptions of the Besra. 



Specimen and description of the Kandesruh of Indian Falconry, a 

 species of Sparrow-haiok, I suspect, nearly allied to the Besra. 



Specimen or description of the Gorhesrah which I suspect is the 

 same as my No. 36, a species of Goshawk, differing in its smaller size 

 from the Baz or true Goshawk. 



No. 268. bis. — Whether the Ortygis Taigoor, of Sykes, is a distinct 

 species, or the young bird of the O. pugnax. 



No. 282. — Any information regarding the Black Florikin, its time of 

 appearance in different districts, at what season it is seen in a state of 

 chauge, &c. &c. &c. 



II. — On the General Application of Low Steam Power to all Vessels, 

 instead of Sails. 

 It is very surprising that though so much has been done in applying 

 Steam Power to move vessels at high speeds for the conveyance of pas- 

 sengers, it does not appear that as yet, any considerable trials have been 

 made of it, for the conveyance of merchandize at moderate rates. The 

 quantity of fuel and power of engine requisite to propel a ship at high 

 speeds is so'great, that for a voyage of any considerable length, the ves- 

 sel is almost taken up with them, leaving so little room for merchandize 

 that it will not answer, except principally employed in the transport of 

 passengers. But this is no reason that it should not answer to use
