content: These four cardboard boxes contain glass lantern slides that were used in lectures on number theory. Each slide consists of two pieces of glass with handwritten or printed words sandwiched between the two panes (using black paper tape). The boxes are numbered 1 through 4. Boxes 1 and 2 each contain six slides, box number 3 contains seven slides and box number 4 contains seven slides.

label: Description
content: The slides in the first box relate to polygonal numbers, with examples triangles, squares, pentagons, and hexagons. Slides in the second box relate to prime numbers.Slides in the third box relate to amicable numbers, the standard form of a number (in its prime factors), powers, and Fermat's conjecture. Slides in the last box concern perfect, abundant, and deficient numbers, known primes, and Wilson's theorem.
