At first I was surprised about how in-depth Jefferson made this report. These classes are uncommon subjects, but Jefferson still found them important to the University. He could have just easily said general subject fields, but he listed every little detail he could think of. However, I shouldn't be necessarily surprised either because Jefferson did take pages to answer a fairly simple question in Query XIV: http://xroads.virginia.edu/~HYPER/JEFFERSON/ch14.html
Here again he went into every little detail. -Alexa Bartels
