[alt-photo] unimportant casein factoid

[Christina Anderson]

Dear All,
So I've started back (finally out of tenure hell for the second time) researching casein and came across this funny factoid from the late 1800s. They differentiated between "the country cow and the town cow with the iron tail," essentially that the town cow was not fed as well as the country cow, and thus the casein content of the milk was lower than 4% and therefore did not coagulate/produce as good a caseine for photography. Funny.

Anyone still working out the casein kinks?
