would commence when the fishing season ends, and his industry-

* Mr. McClelland observes, that it must have been long known, that the 

 difficulty of preserving meat depends more on the state of the atmosphere in 

 regard to electricity and moisture, than on temperature, &c. With salt and other 

 means at hand, he conceives there would be no difficulty in curing fish in an 

 Indian climate in the months of November and December, when the Sullea fishery 

 could be carried on. On this subject, of very considerable interest, Mr. 

 C. K. Robison, one of the magistrates of Calcutta, remarks : " It would be 

 a famous thing if these enormous fish (the Sullea) could be cured, as well as their 

 Isinglass obtained ; and I cannot help thinking the measure very feasible, if the 

 fishermen at the time of taking them and cutting them up, dipped them first into 

 weak chloride of soda, mixed with a small quantity of impure pyroligneous acid. 

 This would not only preserve the fish till the salt acted, but improve the flavour." 

 The pyroligneous acid, or a solution of Creosote, would probably produce the 

 desired effect; if Mr. R.'s hint is followed literally, the mixture would produce an 

 acetate of Soda.

By a Vote of the German Diet, the sum of 1 00,000 florins 

 has been awarded to the Inventor of the Electro-magnetic 

 Engine. The following pages are faithfully translated from 

 the second and improved Edition of the original German 

 Work, of which one thousand copies were sold in the short 

 space of a week. In it will be found a report of the Experi-

 Wagener, &c. with every improvement to the present time. 



* Mighty and vast is the influence which Steam (since the commencement 

 of the present century) has exerted on all the relations, as well of nations as of 

 individuals. It has served to facilitate the intercourse between lands the most 

 distant, and has confessedly exerted an influence on tbe face of empires, more 

 incalculable in its effects than any previous invention to which the mind of man 

 has given birth. For England, especially, it has served to consolidate the
