BRITISH MUSEUM (NATURAL HISTORY). 65 



A new microscope, showing in rotation twelve slides o£ fleas, 

 lice and bugs, has been set up on the west side o£ the Hall ; the 

 interest of each of the specimens in its relation to the spread of 

 disease is indicated in a label placed by the side of the microscope. 



An explanatory guide-book to the specimens and models of 

 disease-spreading insects and ticks exhiliited in the Hall is in 

 preparation, the pamphlet being to a large extent a compilation of 

 the labels that are attached to the specimens displayed, redrafted in 

 such a manner that they read consecutively. The guide-book will 

 be illustrated by fourteen text-figures, and consist of about fifty 

 pages.
