Revieivs — Our Scientific Journals. 41o 



prefaced by a statement of tlie reasons Tvliicb. compelled tlie author 

 to print and circulate this paper at his own cost among the Fellows 

 of the Geological Society of London. Space will not permit us to 

 enter into a prolonged account of Mr. Jukes's pamphlet here, but 

 those who care to leam the whole matter, will find it very fairly 

 argued in the pages of the Jxily Quarterly Journal of Science. We 

 give the writer's concluding remarks : — " After a careful examination 

 of the evidence, we are unable to come to any other conclusions than 

 the following: — (1) That Mr. Jukes, forgetting the Society's rules, 

 has felt aggrieved at the refusal to publish in full a paper whose fate 

 he would doubtless have predicted, had he remembered the Society's 

 regulations ; and (2) that he has precipitately written and printed an 

 attack on the Council of the Society, without first ascertaining that 

 his recollection of the Society's rules was sufficiently exact — a course 

 which can only be compared to rushing into a lawsuit without legal 

 advice, on the strength of vague impression, and with no real know- 

 ledge of facts." 



3. The Popular Science Eeview (No. 23) for April contains, 

 among other interesting original articles, one by Dr. J. D. Hooker, 

 F.E.S., " On the Struggle for Existence amongst Plants." In it the 

 writer shows that there is great truth in the saying (attributed to 

 Dean Herbert, of Manchester), that " Plants do not grow where they 

 like best, but where other plants will let them," and that circum- 

 stances of climate and soil are not omnipotent in regulating the 

 distribution of vegetable life. The writer gives numerous instances 

 of the way in which one class of plants affect the progeny of another 

 class ; grasses and herbs, for example, smothering the seedlings of 

 large and prolific trees. Dr. Hooker also cites some of the most 

 remarkable changes which have been produced upon the floras of 

 new countries wherever European emigration has introduced foreign 

 plants, particularly in the spread of many of our commonest wild 

 plants, and field and garden weeds. No instance can well be found 

 more interesting than the change effected in New Zealand since first 

 visited by Captain Cook, both as regards plants and animals. The 

 domestic pig has run wild, and multiplied to such an extent on the 

 eastern side of the island that parties employed for theii* destruction 

 have been known to shoot as many as 22,000 on a smgle sheep-rtm 

 without any apparent diminution in their numbers. The Norwegian 

 rat, the European mouse, and other old-world pests have found their 

 way out there, and actually dispossessed the native species. The 

 Maoris, who are keen observers, have this saying, "As the white 

 man's rat has driven away the native rat, as the European fly drives 

 away our own, and the clover kills our fern, so will the Maoris 

 disappear before the white man himself." 



There is also an article on the Flint Flakes of Devon and Corn- 

 wall, by Spence Bate, Esq., F.E.S., which is well deserving the 

 attention of Quaternary Geologists. 



The July number (24) has a contribution by Mr. W. Carruthers, 

 F.L.S., " On the Botany of a Coal-mine." It is very gratifying to
