now Charlie, is your physics prac due on tuesday?

If the galvanometer was in parallel with the resistor the current would be split . The series resistor provides some protection from voltage while still allowing all the current through the device.

The practical reason is if you design a circuit with some additional series resistance, that helps greatly to "linearize" the galvanometer response.
