II. — The New Geological Museum at Cambridge. 

 By F. R. CowPER Reed, M.A., F.G.S. 

 rjnHE Geological Department at Cambridge is at length provided 

 X with adequate accommodation by its transference to the new 

 Sedgwick Memorial Museum. The portion of Cockerell's Building 

 formerly occupied by the Woodwardian Museum has been vacated 

 and put at the disposal of the Univei'sity Library ; and the 

 well-known name is only perpetuated in a special portion of the 

 exhibition galleries in the new building containing the founder's 

 collection. 



The Sedgwick Museum is the second Geological Museum at 

 Cambridge which has been erected mainly through the liberality of 

 the public. For, when in 1835 it was decided by the University to 

 build a museum for geology, the sum of £23,400 was collected by 

 public subscription, and to this was added £4,000 of Woodwardian 

 Trust money. Cockerell's Building was erected with the help of 

 these funds, and to the geological collections were assigned the two 

 lower floors. The inadequacy of this accommodation, owing to the 

 growth of the department and the increase in the size of the 

 collections, has been only too apparent for many years. On the death 

 of Professor Sedgwick in 1873 it was decided that his memorial 

 should take the form of a new and larger museum ; and in that year 

 a public subscription was opened for this purpose, and a sum raised 

 which ultimately amounted to over £28,000. The public recognition 

 of the value of the Geological Department at Cambridge has thus 

 been shown in a very substantial and liberal manner on two 

 occasions. 



After a long series of disappointments and difficulties the 

 indefatigable energy and perseverance of Professor Sedgwick's 

 successor, Professor T. McKenny Hughes, have triumphed over the 

 countless obstacles which hindered the realisation of the scheme. 

 The history of the efforts which have been made to find acceptable 

 plans need not here be given, but it should be mentioned that the
