To Monsieur Amedee De Grehan Phra Siam Dhuranurax^[2] the consul for Siam^[3] in Imperial city of Paris in French Empire 18 Rue D'Amsterdam called Siamese consulate.

My consul & intimate friend!

After the day in which my last letter to you was despatched from Bangkok I left my home down to sea & came here & arrived at Place where we pointed out as the place of centeral line of the solar total Eclipse now getting near & where we have prepared for dwelling on seeing the Eclipse as well as certain French men of Sciences came by the French Imperial man of war & a gunboard "Ferlon"^[4] from Saigon and placed their various Surveying & astronomical instruments for seeing the Eclipse near to my place at only a few yards. I was saluted with 21 guns on board man of war & treated with great respects by the French but I am sorry to see the sky was thickly cloudy day & night every day so we & those French men are fearing that maybe be disappointed to see the most remarkable total Eclipse on 17th & 18th inst. for the Sky being continually so cloudy as on several days last until the present day also I have learnt here that certain number of our workmen sent for preparation of our dwelling place on land here became attacked by wild fever usually occurring at ...^[5] gold mines which are near to this place at about only 2,5-miles^[6] so I fear least^[7] many who are accompany me now may be attacked with such the Awful fever if I would land and live on ground of wild fever for several day so that I have resolved to retreat to be anchored at Phu Manaw^[8] near the town of Whaawan I will wait until the nearest day of the Eclipse the French consul Monsieur ... will come down here in about 14th^[9] inst. by board of our gunboat Impregnable which was ordered to take several passengers from Bangkok to be here. The commander of the French Man of war anchored here told me that after two month the vice Admiral De Grandier will return to Saigon but this news were not mentioned in your letter privily or in very private written me by you relating to the intelligence of the said Admiral Grandier & arrival at Paris ...

I beg to remain your faithful S P P M Mongkut R S
