VIII.— On the Homdothermal method, of Acclimating Extra-Tropical 

 Plants within the Tropics. — By Robert Wight, Esq. m. d. &c. &c. 



TO THE EDITOR OF THE MADRAS JOURNAL. 



Dear Sir,— Believing the views, propounded in the accompanying 

 observations on the acclimating of extra-tropical plants in tropical 

 climates, of much importance to this country, I am very desirous of 

 having them speedily subjected to the only test that can determine 

 their value — carefully conducted experiment — both in India and Eu- 

 rope : you will therefore much oblige me by giving them a place in 

 the forthcoming number of the MoAr as Journal. Early publicity is 

 desirable, because it is to the philosophers of Europe (enjoying as they 

 do unrivalled' facilities for conducting the enquiry, as well by the juxta- 

 position of two climates, as by their skill in performing experiments) 

 that we must look for the final determination of the truth or fallacy of 

 my deductions from the few facts already ascertained. As the paper 

 was originally written while encamped on the Pulney mountains, sepa- 

 rated alike from books and every collateral source of information, I do 

 not hold myself responsible for having overlooked the works of other 

 labourers in the same field, if such there be, for truly I know of none. 

 The principles have long been public property, but their application, 

 in the manner here proposed, has never, I believe, been recommended 

 by any one. 



I remain, dear Sir, 

 Salem : 2ilh November, 1836. Yours, &c. 



Robert Wight,
