July 3—Mr. Du Ponceau announced that the Society would receive at 
their hext meeting the Anamitic and Latin, and Latin and Anamitic Dic- 
“onaries, lately published by the Right Reverend Father Taberd, Bishop 
of Isauropolis, and Vicar General of Cochin China, which he had men- 
toned to the Society at a former meeting as in course of publication. 
This valuable work was. printed at Serampore, under the auspices, and, 
'S understood, at the expense of the British government in India, and 
of the East India Company, to whom the learned world are already in- 
debted for the publication of the important labors of the late Dr. Morrison, 
and other works, which have thrown considerable light on the Chinese 
language, and who are now, with the same liberality, extending the know- 
ledge of the Indo-Chinese idioms, which, until lately, were entirely un- 
known in America and Europe. It will not be forgotten, Mr. Du Pon- 
ceau added, that this Society was the first to make known the Anamitic 
language, by the publication of Father Morrone’s French and Cochin 
Chinese Vocabulary, and of the Latin and Cochin Chinese Dictionary, 
muse among the missionaries in Cochin China, which works, though 
ee So full. and so complete as those published by Bishop Taberd, were 
€ first to shed light on that branch of philological science.
