I have a bound copy of Volume 16 [1] which as far as I can tell was just assembled from the unsold issue at the end of each year. Unfortunately they require a subscription to view the online archive and it feels very different when you've got an extant physical copy. IIRC the machine gun story was page 1 and the first letter about aluminum was page 2 or 3 of issue 1. There was also a really interesting exchange between some laymen and a scientist about the nature of meteor but that was half way through the year. Both had some really crazy theories. Most of the interesting stuff like that is hidden throughout. [1] https://www.scientificamerican.com/magazine/sa/1867/01-05/ https://www.scientificamerican.com/magazine/sa/1867/01-05/
