species by means of natural selection as a superficial conjecture, and 
hopes for a speedy recognition that Darwin’s deduction, as he calls it, 
was a most unfortunate one. Supposing it to have been so, the world 
could well do with one or two more misfortunes of a similar kind. 
Dr Hansen’s book is in English. This is evidently part of a 
conspiracy to discourage the English-speaking peoples from studying 
foreign languages, a plot in which Russia has, unfortunately, not yet 
joined. The translation from the Danish manuscript has been well 
executed by Miss Louise von Cossel. It is unlucky that one fre- 
quently recurring word has been too literally rendered ‘list,’ not in 
any of the accepted English senses of the word, but to signify a ridge 
or linear prominence, or possibly a seam or an unraised line of 
hardening of the integument. In naming the mouth organs Dr 
Hansen himself adopts the terms maxillulae and maxillae, respectively 
for the first and second maxillae, on the analogy of antennulae and 
antennae for the first and second antennae. The great objection to 
these terms is that sometimes the first maxillae and the first antennae 
are larger, even very much larger, than the second, and then the 
» diminutives are misleading. As a matter of fact, in a paper published 
only last year by F. Vejdovsky, the second antennae are called the 
antennules. The confusion is not unnatural in describing Amphi- 
pods, which often have the second antennae shorter than the first, 
occasionally less than one-fifth as long. But these are not matters of 
vital concern. For the pith and marrow of the research the reader 
must have recourse to Dr Hansen’s volume. It is a masterly piece 
of work, which will confirm and increase his high reputeas a 
naturalist of distinction. Toe &: 
PREHISTORIC PROBLEMS, being a Selection of Essays on the Evolution of Man and other 
Controverted Problems in Anthropology and Archaeology. By Robert Munro, 
M.A., M.D. 8vo, pp. xix. + 371. London: Blackwood, 1897. Price, 10s. - 
In these days of scattered scientific literature, the bringing together 
into a single volume of a number of essays by one author is a very 
desirable thing, particularly when, as in the present instance, the 
author is a scientist of distinction. Although the volume contains 
comparatively little that has not already appeared in print, Dr 
Munro's newly-published selected essays on “ Prehistoric Problems ” 
will be welcomed by many as a valuable addition to Archaeological 
literature. The book consists of a number of chapters, each of which 
is a separate and distinct essay. This collection of essays is of a 
decidedly heterogeneous nature, comprising as it does so varied a 
selection of subjects as: The Rise and Progress of Anthropology ; 
Man’s Antiquity and Place in Nature ; Prehistoric Trepanning ; Otter 
Traps; Bone Skates ; and Prehistoric Saws and Sickles. The very 
varied nature of the subjects discussed imparts a character of in- 
equality to the volume, and imposes a certain lack of proportion, 
which is evident to the reader who, taking the book as a whole, 
would read it straight through from beginning to end. Taken indi- 
vidually, the essays are decidedly both instructive and interesting, and 
the first four, which form Part I. of the volume, may well be taken 
together, as they form a very fairly connected and consecutive series.
