In the pursuit of "Scala Graduum Caloris" Hello dear members of the forum! I would like to ask for your help! I'm doing a science project for which I need Isaac Newton's research paper on The Law of Cooling. As I understand the topic is covered in his paper "Scala Graduum Caloris" which obviously is in Latin. I have been digging through the web but could not manage to find a translated version of this paper. Alternatively, I have heard that prof. Crichton Mitchell in 1887 reviewed this paper to point out some misunderstandings, again, I couldn't find a paper on that (there was possibly something in one of the reviews I found but that costs $45 which is much too much for me). P.S. If this could be of any help then I have to point out that I am particularly interested in finding out what exactly did Newton say about the requirements for his law to be true because I have found non-referenced citations that mostly it has been misunderstood and that actually Newton pointed out the requirement for the ambient environment to be actually a current of air (aka breeze) for his law to be true but most textbooks have missed out on that (wikipedia also). Thank you!
