I want to emphasise perhaps a little bit about the degree structure at Melbourne University because it's quite different from what it now is and what is, I think... Well, it's a little bit like the Scotch system, but not like the one in England. The system was that you took four subjects in the first year, three subjects in the second year and two subjects in final year, but the two subjects could be A and B parts of the same subject. So you could do double chemistry or chemistry and metallurgy, chemistry and geology, and so forth. That was the technical part, but also in Melbourne in those days you had to do two years of French and two years of German. These were translation exercises; if you'd done Pass Sixth, as I had in French, you were excused the first year. If you'd done Honours Sixth, which I hadn't done, you had to do the second year of French, and in German... I had no German – I'd done Latin at school as a second foreign language – then you had to do that from scratch. So that was added on to the course.
