ing their share in almost hard work. Although this is a double testimony 

 in its favor, it is as impossible, nevertheless to deny, as it is painful to 

 acknowledge, that hitherto, these coasts have proved most fatal to 

 Europeans, that sailors, soldiers, and civilians, have alike fallen victims 

 to its fever, and on Chedooba an ample share ; nor may there be a doubt 

 thrown on the attention and ability of those medical officers whose exer- 

 tions have yet hitherto failed in all attempts to stop its fatal progress. 

 Whether therefore this country is one from which the European is to be 

 ever thus excluded, or whether in the progress of all other improvements, 

 and also if the character of his treatment by himself or by others may be 

 found hereafter to enable him to make here also his temporary home, and 

 introduce, with his wealth, his intelligence, his energy, and above all his 

 religion, their attendant blessings, must apparently be left for the future 

 to shew. But giving to the facts, which constitute this favorable evidence, 

 no more than the weight, they are strictly entitled to — and others may 

 be found perhaps to entertain with me, even more than the hope, that 

 some such improvement may eventually render the climate of Chedooba, 

 and also that of Arracan, no longer so fatal a bar as hitherto, to the 

 advance in these provinces of the Civilization of Europe.

Memoranda on the ( Chulchulheera' of the Hills, and on some Lic- 

 hens from the Himalayas in the Collection of the Asiatic Society. 

 By Henry Piddington, Offg. Curator, Mus. Asiatic Society. 



My attention having been directed to this subject by our President, 

 1 took the opportunity, when examining the * Chulchulheera,' to test also 

 some lichens sent to the Asiatic Society from Simlah, in 1838, by Mrs. 

 Siddons, which I found in the Museum. I have thought it worth while to 

 make known the results of my work, and to add a few remarks which 

 have occured to me, in the hope of drawing attention to this very inter- 

 esting though neglected subject. 



I subjected the ' Chulchulheera ' to the common ammoniacal test, 

 and found that it yielded a tolerably bright red brown liquid, though 

 not the violet red described by Hellot ; I did not succeed in pro- 

 ducing any substantive dye with it, though using several mordants, 

 I essayed to manufacture some kind of Cudbear from it also, but 

 did not succeed. The preparation of Cudbear however depends upon two
