PREFACE. Vll 



work on the Navigation of the Indian Ocean by the illustrious 

 Von Hammer of Vienna. The seasons and the modes of reck- 

 oning set forth in the Mohit are still followed by the Arab 

 navigators who frequent the port of Calcutta ; the Editor in 

 passing the article through the press derived much information 

 from some of the Nakodas, who recognized and pointed out 

 almost all the places enumerated in the Arabic work. 



If the existence of the Journal has in any way promoted the 

 acquirement or the preservation of any of the knowledge which 

 its pages boast of containing, the Editor is fully rewarded for the 

 labour, and for the sacrifice of time that has necessarily been de- 

 manded in more than an ordinary measure, where correspon- 

 dence, arrangement, correction of the press, and publication 

 have fallen on one individual, who has had moreover only the 

 hours of leisure and recreation to devote to the purpose.
