Your favor of the 26th. came to hand last night. that of Jan. 30. had been recieved in due time. with more business than can be dispatched at once, I am often obliged to lay by to a more leisure moment that which will best bear delay. this lot falls often on my philosophical and literary correspondence. to this circumstance alone is owing the omission to answer that part of your letter which...

At the date of my last I intended to have had an immediate personal communication with Dr. Mitchell on the subject of yours of the first inst.

The favor I meant to ask of you was to chuse me two thermometers descending as far below zero as you can get them. the kind preferred is that on a lackered plate slid into a mahogany case with a glass sliding cover, these bearing best an exposure to the weather. I have had so many broke in coming from Philadelphia by the stage that I am authorised to recommend the packing them in a box at...

I mentioned to Baron Humboldt my proposition for taking lunar observations at land without using a time piece. he said there could be no doubt of it’s exactness, but that it was not new, that even De la Caille had proposed it and De la lande had given all the explanations necessary for it, I think he said in his 3d. vol. I have not the book here but presume you can consult it in Philadelphia...
