Boats for River Navigation. 



[March, 



has been separated from Capra and from Damalis by the circumstance 

 of the cores of the horns being solid in the former and sinused (so to 

 speak) in both the latter. Nevertheless, I am well acquainted with three* 

 species, besides the Chiru, in which the cores of the horns are not solid, 

 though the whole four are still retained (and of necessity) in the Ante- 

 lopine genus. It would be easy to multiply instances, from the best 

 and most recent works, of new sub-genera, which have been set up upon 

 the strength of diagnostics of far from general prevalence, that when 

 you come to examine carefully, the several species classed under any 

 one of them, the rule too frequently turns out to be the exception ! For 

 example, the subgenus Namiorhcedus is chiefly designated by the pre- 

 sence of the intermaxillary pouch : but of the three species contained in 

 it, two are perfectly familiar to me (Ghoral and Du Vaucellii), and nei- 

 ther has a trace of any such organ.

VI. — Comparative Section and Tonnage of English and Indian Boats for 



River Navigation. 



The advantage to the internal commerce and agriculture of this 

 country, likely to arise from the improvement of the communications 

 both by land and water, are too well known to require pointing out : 

 but the means of effecting this improvement appear to be very much 

 neglected ; and the object of the following observations therefore is to 

 shew to those interested in the inland navigation of Bengal, the man- 

 ner in which they may benefit themselves by reducing the cost and 

 facilitating the conveyance of goods by water carriage. 



The alteration in the present system recommended is a better con- 

 struction of the boats, both in their proportions and in the manner of build- 

 ing them ; and, as examples are more satisfactory to general readers, than 

 theory or calculations, a table is given, containing the dimensions of 

 several boats used for river and canal navigation in England, and for 

 the sake of comparison, a few boats now in use on the Hoogly river.
