My high school biology class was in the 1963 or 64. I can still remember the smell of the formaldehyde to this day, just like I can still remember the smell of the ether they gave me when I had my tonsils out at age 5.
Formaldehyde. I had 6 months of gross humam anatomy (and it was grosss). First day when boxes were opened, started hearing thuds when people passed out and hit the floor. Morning class. formaldehyde smell carried into lunch. Eventually got callous and used to it. Couldn’t get smell off your hands,
