Stunning illustrations of magnified pollen from 1873

These stunning illustrations of magnified pollen from 1873 fill me with joy and cause a psychological tickle in my nose. Pollen, my long time enemy, is actually quite beautiful when it's magnified and not causing me to have a sneezing fit. 

All of these drawings are gorgeous, but the alien-like shapes on page 4 are my favorite. I love knowing that all of these tiny strange objects are hidden in plain sight everytime I take a nature walk.
