ON MAKING ICE IN INDIA. 

 vSiR, Edinlurgh, 1793' 



X HE following procefs of making ice in the East 

 Indies, was communicated by Sir Robert Bavkei" 

 F. R. S. in a letter to Dr Brocklesby, which 

 was pubjiflied in the Philosophical Transactions. 

 lf.it meets vrith your approbation, your inserting 

 it in your Miscellany will oblige, Sir, your humble 

 servant Amicus. 



The procefs of making ice in the East Irrdies ha- 

 ving become a subject of speculation, I beg permif- 

 sion to pr&sent you with the method by which it 

 was performed at AUabahad, Mootegil, and Calcut- 

 ta, in the East Indies ; lying between 25* 30, and 

 23° 30, of north latitude. At the latter place, I 

 liave never heard of any person living discovered 

 i>a; ral ic^ in the pools or cisterns, or in kny wa- 

 ters collected on the roads ; nor has tlie thermome- 

 ter been remarked to descend to the freezing point ; 

 und at the former, very few only have discovered 

 •ice, and that but seldom : but, in the procefs of 

 making ice at these places, it was usual to collect 

 a quantity every moriiing, before sun rise, Cexcept 

 in some particular kinds of weather, which I fliall 

 tpecif^ in the sequel,) for near three months in the 

 vcar vi-z. from December till Febiuarv.
