40. Jameson's ' Story of the Bear Column.' 



[Story of the Rear Column of the Emin Pasha Relief Expedition. 

 By the late James S. Jameson, Naturalist to the Expedition. Edited by 

 Mrs. J. S. Jameson. With Portrait, Map, and Illustrations from the 

 Author's Sketches. 8vo. London : 1890. R. H. Porter.] 



Without going into the controversy about the "rear 

 column/^ we may say that the plain and unvarnished tale 

 told in the late Mr. Jameson's Journal fully explains 

 several rather obscure points in the stories told against him. 

 After reading it none of his brother naturalists will believe 

 Mr. Jameson to have been guilty of the wanton cruelty that

An account of the collection of birds made by Jameson on 

 the Aruwhimi has already been published by Capt. Shelley 

 in this journal (Ibis^ 1890, p. 156). In the 'Natural 

 History Appendix ' to the present volume, Mr. Sharpe gives 

 a general account of Jameson's ornithological work, and adds 

 a series of extracts from Jameson's diaries, which contain 

 his field-notes on the birds of the Congo. It is stated that 

 all the specimens considered to be of value to the British 

 Museum have been presented by Mrs. Jameson to that 

 institution.
