HENRY KEEPING TESTIMONIAL. 



We have been requested to announce that Mr. Henry Keeping, who 

 has been for fifty years Curator of the Geological Museum, Cambridge, 

 is now retiring from active work, and it is felt by many with whom 

 or for whom he has worked that this would be a fitting opportunity 

 for expressing their appreciation of his long service in the cause of 

 Geology. It is therefore proposed to offer him a purse on his retire- 

 ment at the end of the Easter term. 



Subscriptions will be received by Mr. P. R. Cowper Reed, M.A., 

 F.G.S., Sedgwick Museum, Cambridge, and cheques should be made 

 payable to the "Henry Keeping Testimonial fund", and crossed 

 Capital and Counties Bank, Cambridge Branch.
