100 ACCOUNTS, ETC. OF THE BRITISH MUSEUM. 



Progress has also been made with the already extensive 

 collection illustrating the development and metamorphosis of 

 vertebrate animals, and the recent additions include two 

 valuable sets of embryos of Gymnarchus and Protopterus. 



A considerable amount of work has been expended in 

 respiriting and remounting such of the anatomical prepara- 

 tions as were in need of attention, and a few new dissections 

 have been added to the morphological series.
