This report consists of an account of work done under IFPRI contract in Cambridge University during the year to December 1987. The principal achievements during that time are:

1 . Installing pressure transducers on the flow rig and developing the associated software so as to be able to measure the very low pressure differences occurring.

2. The performance of a series of experiments on a hopper of half angle 15 degrees; the results confirming the observations tentatively reported in the last IFPRI report.

3. The development of a possible theory to explain the observation.

Also included is the programme of work proposed for the rest of the contract.
