Observation the Fourth

Here's what I found in my MicroAquarium this week, lots of cool stuff:
Spirogyra (Lund p.109 figure 193)

Difflugia (Patterson p. 95 figure 186)

Euplotes (Patterson p. 124 figure 261)

I also found the Euplotes while dividing:

Litnotus

I also found a diatoms of the genus Navicula, some Flagellaria, and an insect larvae trapped in the bottom corner of the MicroAquarium. The  larvae could be seen clearly without a microscope.
