Just been trying to locate the title of a reference in a CRG Newsletter. (I've found the CRG Transactions database via the BCRA website - but can't seem to find a CRG Newsletter database.)
The reference I have is:

Marston T K & Schofield J, 1962, TITLE? . Cave Research Group Newsletter 84 pp.4-13.

Can anyone easily tell me the title of this article? (It's about dye testing, with reference to the GG system.)

Thanks!

Now sorted.

(Many thanks to Beardy!)
