The following Resolution of the Council was unanimously 

 approved by the Fellows present. It was further resolved that

The Council of the Geological Society has learned with surprise and 

 regret of the proposal of the War Cabinet and the Office of Works to 

 dismantle the British Museum at Bloomsbury and its Natural History 

 Branch at South Kensington, in order to convert the buildings into 

 ordinary piTblic offices. It desires to pi'otest most strongly against this 

 unfortunate blow to the cidtivation and progress of learning in the 

 Empire, and earnestly hopes that the Government's intention may be 

 reconsidered. The Geological and Mineralogical Collections, of which 

 the Geological Society has special knowledge, are continually needed for 

 reference concerning numerous problems that arise in the present crisis. 

 and they cannot be rendered inaccessible without danger to their 

 preservation.
