11From Benjamin Franklin to Cadwallader Colden, 28 February 1753 (Franklin Papers)
ALS : New-York Historical Society I return you herewith Professor Kanster’s Remarks. As far as I am able to judge, the Translation is just, and your Answer a good one. I am pleas’d with the Omission of that part of a Paragraph relating to the German and Pensilvanian Electricians, and have corrected the Copy as you direct. I have but one other Alteration to propose, which is, to omit some Part...
12From Benjamin Franklin to Cadwallader Colden, 14 September 1752 (Franklin Papers)
ALS : New-York Historical Society When I had read your Favour of May the 14th. I resolved to read and consider more carefully Sir Isaac Newton’s Optics, which I have not look’d at these many Years. I delay’d answering, till I should have an Opportunity of doing this; but one thing or other has hitherto hindred. In the Winter I may possibly have more Leisure. In the mean time I would just...
13From Benjamin Franklin to Cadwallader Colden, 14 May 1752 (Franklin Papers)
ALS : New-York Historical Society I find Parker has been indiscreet enough, to print a Piece in his Paper, which has brought him into a great deal of Trouble. I cannot conceive how he was prevail’d on to do it, as I know him to be a thorough Believer himself, and averse to every thing that is commonly called Freethinking. He is now much in his Penitentials, and requests me to intercede with...
14From Benjamin Franklin to Cadwallader Colden, 23 April 1752 (Franklin Papers)
ALS : New-York Historical Society; also draft: American Philosophical Society In considering your Favour of the 16th. past, I recollected my having wrote you Answers to some Queries concerning the Difference between Electrics per se, and Non Electrics, and the Effects of Air in Electrical Experiments, which I apprehend you may not have received. The Date I have forgot. We have been us’d to...

16From Benjamin Franklin to Cadwallader Colden, 11 October 1750 (Franklin Papers)
ALS : New-York Historical Society I have learnt by different hands, that Dr. Mitchel continues in a bad State of Health, which I suppose obliges him to drop his Correspondencies. ’Tis a Loss to us all. Messrs. Bertram and Evans did not go their intended Journey to Lake Erie, but are both safe at home. Mr. Weiser is just return’d from Onondago, and gives a melancholly Account of the declining...
17From Benjamin Franklin to Cadwallader Colden, 28 June 1750 (Franklin Papers)
ALS : New-York Historical Society I wrote a Line to you last Post, and sent you some Electrical Observations and Experiments. You formerly had those Papers of mine out of which something has been taken by Mr. Watson, and inserted in the Transactions: If you have forgot the Contents of those Papers, I am afraid some Things in that I last sent you will be hardly understood, as they depend on...
18From Benjamin Franklin to Cadwallader Colden, 13 February 1750 (Franklin Papers)
ALS : Historical Society of Pennsylvania I receiv’d your very kind Letter relating to my Proposals for the Education of our Youth, and return you the Thanks of the Gentlemen concern’d, for the useful Hints you have favour’d us with. It was long doubtful whether the Academy would be fix’d in the Town or Country; but a Majority of those from whose generous Subscriptions we expected to be able to...
19From Benjamin Franklin to Cadwallader Colden, 29 September 1748 (Franklin Papers)

I congratulate you on your Return to your beloved Retirement: I too am taking the proper Measures for obtaining Leisure to enjoy Life and my Friends more than heretofore, having put my Printing house under the Care of my Partner David Hall,...
20From Benjamin Franklin to Cadwallader Colden, 27 January 1748 (Franklin Papers)
AL : New-York Historical Society I received your Favour relating to the Cannon. We have petitioned our Proprietors for some, and have besides wrote absolutely to London for a Quantity, in case the Application to the Proprietors should not succeed; so that, Accidents excepted, we are sure of being supply’d some time next Summer. But as we are extreamly desirous of having some mounted early in...
