was floating and a day or two before. 

 Inside the bay the course of the bottle 

 depends largely on whether water is en- 

 tering or leaving the bay, and this de- 

 pends mainly on the direction and 

 velocity of the wind compared with the 

 way it has been blowing for some hours 

 or days before. 



The bottles displaced about 700 cubic 

 centimeters and, except the first 26, 



were weighted with sand to make them 

 sink beneath the board. In a few in- 

 stances bottles one, three, and five feet 

 beneath the surface were started simul- 

 taneous^- . 



An account of these experiments will 

 be published in the next annual report 

 of the Ohio Academy of Science.

This is one of the most important 

 works relating to Africa that has been 

 published in recent years. The com- 

 pletion of the Uganda Railway during 

 the past year, opening this vast equa- 

 torial province to direct communication 

 with the world, makes the work spe- 

 cially timely. Sir Harry Johnston de- 

 scribes the tremendous work done by 

 the British government toward pacify- 

 ing and educating the Uganda peoples. 

 The task is costing many millions of 

 pounds sterling, but the commercial 

 profits that will ensue will, in his opin- 

 ion, far outbalance the expense. The 

 larger part of the two volumes is de- 

 voted to a description of the varied 

 races, the animals, and the plant life in 

 the protectorate. An unusual feature 

 are fift} r colored plates from drawings 

 by Sir Harry Johnston and over 500 

 illustrations from photographs taken 

 by him during his twenty months of 

 exploration in Uganda. The following 

 extract from the author's preface gives 

 a very good idea of the protectorate : 

 ' ' The territories which are comprised 



within the limits of the Uganda Pro- 

 tectorate during the time of my admin- 

 istration of that portion of the British 

 sphere in East Africa certainly contain 

 within an area of some 150,000 square 

 miles nearly all the wonders, most of 

 the extremes, the most signal beauties, 

 and some of the horrors of the Dark 

 Continent. Portions of their surface 

 are endowed with the healthiest climate 

 to be found anywhere in tropical Africa; 

 yet there are also some districts of ex- 

 treme insalubrity. 



' ' The Uganda Protectorate offers to 

 the naturalist the most remarkable 

 known forms amongst the African 

 mammals, birds, fish, butterflies, and 

 earth-worms, one of which is as large 

 as a snake and is colored a brilliant 

 verditer-blue. In this protectorate there 

 are forests of a tropical luxuriance onh- 

 to be matched in parts of the Congo 

 Free State and in the Cameroons. Prob- 

 ably in no part of Africa are there such 

 vast woods of conifers. There are other 

 districts as hideously desert and void of 

 any form of vegetation as the worst part 

 of the Sahara. There is the largest 

 continuous area of marsh to be met 

 with in zcny part of Africa, and perhaps 

 the most considerable area of tableland 

 and mountain rising continuously above 

 6,000 feet. Here is probably reached 

 the highest point on the whole of the 

 African continent, namely, the loftiest
