The Committee recommends that the following directions for 

 working be communicated to the various workers : — 



1. When possible, a typical measured section should be given of 

 each locality examined, with notes of as many confirmatory sections 

 as possible. 



2. Any specimen not actually found in situ to be labelled to that 

 effect, with the exact conditions under which it was found noted. 



3. All specimens should be labelled with the local name of the 

 bed, giving as many additional details as possible, and in all cases 

 the exact locality, which should further be ' noted on a largo 

 scale-map. 



4. All specimens should be labelled wlxen found. 



5. So far as possible, workers are recommended to collect from 

 one bed at a time, and to pack the specimens from each bed in 

 a separate parcel before commencing to collect from another bed. 



6. Attention should be paid to apparently identical forms 

 separated by many feet or yards of deposit, as the forms may bo 

 mutations; large suites of such specimens should be collected; 

 indeed — 



7. As large a number of specimens as possible should be obtained 

 of each species in every bed examined. 



8. Absence of fossils in any bed should be noted whenever 

 possible. 



9. Attempts should be made to record the relative abundance of 

 fossils, which may be roughly done by recording those which are 

 very rare (v. ?•.), rare (r.), common (c), and very common (y. e.). 



10. In case of beds being obviously rich in micro-organisms, large 

 pieces should be collected for future examination. 



11. Considering the importance which cherts have assumed, it is 

 very desirable to collect specimens of cherts. 



Specimens may be kept by the discoverers or forwarded to the 

 Secretary of the Committee (E. J. Garwood, Dryden Chambers, 

 119, Oxford Street, London, W.), on loan or for retention. 



The Committee recommends that the names of those whom they 

 have mentioned as likely to undertake the charge of districts be 

 added to the Committee, and that the following palaeontologists be 

 asked to co-operate with the other members, and to identify such 

 fossils as may be submitted to them, their names being also added 

 (when not previously mentioned) to those of the Committee : 

 Dr. G. J. Hinde (radiolaria and sponges), Professor H. A. Nicholson
