Africa is referred to Toddalia lanceolata. At the time of the 
Colonial and Indian Exhibition in 1886 this remarkable wood 
attracted a considerable amount of attention, in consequence of its 
greasy nature 1 
machine bearings. It was used for this purpose in the diamond- 
referred to a leguminous tree, Milletia caffra. The wood is very 
distinct from that of the Toddalias, which Mr. Boulger rightly 
describes as white, hard and tough, while that of the Umzimbit 
used in the Colonial Exhibition machinery was distinctly marked 
by a purplish pink heart-wood and white tap-wood; so that it 
seems there is still some doubt about its identification. 
€ were somewhat surprised at not finding in the pages of the 
book the name of Mr. Herbert Stone. His paper on “‘ The Identi- 
fication of Wood,” published in the Journal of the Society of Arts 
for Dec. 6th, 1901, is a noteworthy contribution to the history of 
the subject. ba - oe

In this volume Professor Bose has put in a connected form the 
results of work extending over some years, which have been pub- 
lished in various memoirs by the Royal, Linnean, and other learned 
societies. The portion dealing specially with plants forms the 
subject of a paper which botanists have before them in a recent 
number of the Linnean Society’s journal. In that communication

in the inorganic. There is in it no element of mystery or caprice, 
such as we must admit to be applied in the assumption of a hyper- 
mechanical vital force, acting in contradiction or defiance of those 
physical laws that g the world of matter, Nowhere in the entire 
range of these response-phenomena—inclusive as that is of metals,
