PSYCHICAL RESEARCH. 

 The Trend of Psychical Research. 

 —By H. A. Dallas. 49 pa^es. 

 fvin.X4j(-in. 

 (John M. Watkiiis. Price bd. net.) 

 Diirint; the thirty years that it ha^ 

 licen established, the Society foi 

 Psychical Research has accumulated 

 a vast number of facts in the obscure 

 domains of psychology, distinguish- 

 ing the genuine phenomena from 

 the tricks of " spiritistic " charlatans. 

 thus rendering valuable scientific- 

 service to the world. But as Miss 

 Dallas (who is a well-known investi- 

 gator of these matters) argues, thi 

 business of science is not merel> 

 to collect data, but also to frame 

 theories in explanation of them. Shi 

 thinks, and most persons who have 

 studied the subject will agree witli 

 her, that the time has now arrived 

 when certain conclusions may be 

 drawn from the data already 

 obtained. These conclusions 

 she formulates as follows : — 

 "1. The reality of an un- 

 seen universe of in- 

 telligent life. 



2. Man's survival of bodily 



death. 



3. That communication 



takes place between 

 the (so-called) livins 

 and the (so - called i 

 dead." 

 In the essay under review, 

 which was originally de- 

 livered as a lecture to the 

 Quest Society and has been 

 reprinted from The Quest, 

 she briefly states some of 

 the evidence upon which 

 these conclusions are based. 

 It is of a most interesting 

 nature, and the writer's 

 arguments are well (i( of 

 necessity briefly) put.

 A great love of natuic 

 an aptitude for painstaking 

 and ingenious research, as 

 well as the power of writing 

 a pleasing description belong 

 to M. Fabre, and all three 



Crustacea. 



have been combined to produce the 

 essays which make up this volume. The 

 subject of dung beetles does not at the 

 outset so(md inviting, but M. Kabres' 

 account of the sacred beetle and its 

 work, as well as that of the Spanish 

 Copris and Minolanrus typhacus 

 is most interesting and delightful. 

 Beetles are not by any means the 

 only creatures dealt with, for the 

 scorpion's courtship is described, as 

 well as the habits of some solitary 

 wasps and bees. The ringed Call- 

 enrolls should be specially mentioned, 

 which first stings its spider-prey in 

 the month in order to paralyse the 

 fangs, and then in the body to keep 

 the legs still. M. Fabre digresses to 

 describe Pasteur's call upon him 

 previous to the investigations which 

 I lie great bacteriologist made on silk- 

 Mirm disease. At that time Pasteur 

 :i.id never seen the cocoon of a silk- 

 ■ iirm nor did he know that there 

 V .is a chrysalis inside. VVe are 

 i.indly permitted by Messrs. Black 

 to print one of the illustrations (see 



Figure 292).

Dr. Caiman has produced 

 a truly scientific, but at the 

 same time, an eminently 

 readable book, and this 

 because he has picked out 

 from the wealth of his in- 

 formation with regard to 

 Crustacea many points 

 which are of general interest. 

 Some specialists are not 

 capable of doing this, which 

 is a pity, for one of the 

 important ways of advancing 

 any particular branch of 

 science is by attracting new- 

 workers into the field. In 

 " The Life of the Crustacea " 

 -we are told of Crabs which 

 use a shield, such as the 

 valve of a shell or a man- 

 grove leaf, and carry it 

 about ; of forms which rear 

 their young in a brood pouch 

 like the opossum shrimp and 

 the wood-lice : of hermit 

 crabs that live, not in the 

 coiled shell of some dead 

 mollusc, but in a piece of 

 hollow water - logged stem, 

 and are quite symmetrical ; 

 not to mention such little- 

 known species as the well- 

 shrimps which dwell in 

 subterranean waters. These 

 and many other subjects are 

 attractively brought before 

 ns with the help of some 

 excellent illustrations (see 

 Figure 291, which is repro- 

 duced by the courtesy of the
