Deputy Kelly may ask a supplementary on Question No. 16.

In relation to the latter part of the Minister's answer, when he said that we would require the forthcoming census to give us any reliable picture of the emigration trend, may I ask him what feature of the census due in 1979 will reflect emigration?

There is a later question. If I get to that I will give a full answer.

The Minister is interrupting again.

That Deputy has a question down which I will answer.

On a point of order, is it proper for a Minister to refer to a Deputy as that Deputy and to point his finger across the House?

My apologies to Deputy Kelly.

Would you consider, Sir, asking the academics on both sides of the House to perhaps treat the House with a little less heat and more illumination in some of the replies.

I thank Deputy Quinn for referring to me as an academic.

Question No. 17 postponed.
