Fig 9. Log-Log plot representing the evolution of the rate of formation of aqueous humour (Q) with the volume of the anterior chamber (V_ac) in various vertebrates.

A fit (plain line) was obtained through model averaging. The rate of formation of aqueous humour was found to scale as $Q\sim {\text{V}}_{ac}^{0.67}$ , which is in agreement with scaling Eq (10).
