Dr. Free-Ride’s parents, Duke and Super Sally, have been working hard to shed some of the material goods they have accumulated in the last several years, on account of they are planning a move to smaller living quarters.
Of course, this means that they shipped several boxes of stuff from their current place to Casa Free-Ride. There’s some sort of conservation of matter principle at work here.
Not that I should complain. For one thing, half of those boxes are actually Uncle Fishy’s. For another, there’s some stuff cool stuff in the boxes that are staying with us.
There are, as expected, the old photos. I believe this one was taken before my parents brought me home from the hospital.

There are others from elementary school where the 1970s fashions are very, um, striking.
But there are also some really cool nerd accoutrements that my parents must have realized would be appreciated at Casa Free-Ride. Let’s say you have to do some organic chemistry during a power outage.

Whip out the “Chemist’s Triangle” and you can draw all those structures without computer assistance.
Or, if you need to plan the set-up for your next foray into synthesis:

A chemistry stencil with all manner of glassware! How did I live without this?

In that same box, something that looks like it would fit in the pocket of a lab coat much more easily than a CRC Handbook.
This Condensed Laboratory Handbook (copyright 1965 by E. I. du Pont de Nemours and Co.), 44 pages of awesome, has a fold-out Periodic Table of the Elements, the values of fundamental physical constants, a table of logarithms to four places (one more thing you might want during a power outage!), and conversion tables of various sorts.
There’s information on the concentrations of commonly used lab reagents.
There are ionization constants for acids and bases.
There’s a table of various acid-base indicators.
There are recipes for standard solutions of various sorts.
And then, right after the “Laboratory Safety Tips,” the “Safe Practice Suggestions,” the “Checklist for General Laboratory Safety,” and the “Personal Protection Checklist,” we get to the fun stuff — discussions of hazardous chemicals and mixtures.

There’s also information on the recommended ways to package and transport chemicals and explosives.
I reckon people were a bit freer with this kind of information in 1965 than they are nowadays.
