3. The history of the Catholic descendants of the Portuguese and French who are 
settled in different countries in India. In this inquiry the Committee have received 
much assistance from the Abbé Duzo1s, who was so long in India, and who is now the 
Director General of all the Catholic missions in India which are supported by the 
French nation. 
4, The geology of India. ‘The Committee have received an interesting letter on this 
subject, addressed by M. Jacguemonr to Sir A. Jounston, dated at Ladakh, 18th Sep- 
tember 1830, giving a short account of the observations he had made upon the geology 
of the Himalaya Mountains and the other parts of India through which he had 
travelled. They have also been informed by Lord Wm. Bentinck, that his Lordship 
will, as they requested him, distribute to the different surveyors’ departments in British 
India, copies of the instructions which they have sent to his Lordship and to the Hon. 
Sir C. Cotvitte, Governor of the Isle of France, to enable them to collect such informa- 
tion as may be necessary for forming geological maps of the territories under their 
respective authorities. 
5. The botany of India. The Committee have received from Dr. WatticH a most 
valuable paper upon this subject, in which he illustrates the practical advantage 
that may be derived from an attentive observation of the vegetable productions of 
India. 
6. The languages of India. As a very accurate knowledge has already been obtained 
by some of the most distinguished Oriental scholars of many, if not of the whole, of the 
languages that prevail in India, the Committee have devoted their attention more 
particularly to the languages of Thibet, Burmah, Laos, Siam, Pegu, aud Cambodia, 
and those of the islands which extend from Borneo east to Madagascar west. On the 
language of Thibet the Committee hope to derive much information from the labours of 
M. Csoma de K6ros, On those of Burmah, Laos, Pegu, Siam, and Cambodia, the Com- 
mittee have received from Sir A. JounsTon a very interesting paper,* drawn up by the 
Rey. C. Gurstarr, who is at present making a missionary tour through Cochin China 
and the adjacent countries. In the languages of the islands in the Indian and Pacific 
Oceans the Committee continue to receive from Sir C. CoLvitLe, and to forward to 
Baron W. Humsotpz, at Berlin, various important documents. 
7. The laws of inheritance, as they prevail under various modifications in different, 
parts of India. 
8. The history of the Lake Mervis in Egypt, as connected with the history of the five 
great lakes or tanks in the southern and eastern parts of Ceylon, the traditions relating 
to which have induced some persons to suppose that they were constructed upon prin- 
ciples of irrigation derived from Egypt during the commercial intercourse which sub- 
sisted in ancient times between Abyssinia and the island of Ceylon. 
9. The ancient state of agriculture in the northern and eastern parts of Ceylon; the 
commercial intercourse which subsisted in ancient times between that island and various
