The Irish Naturalist

is merely of trophic function and probably also acts as a limiting membrane 

 confining the osteoblasts to their proper sphere. 



Other interesting matters are referred to, such as the deformities 

 and malformations of the antler due to injury or disease, the effects of 

 castration, etc., which add to the value of the work. The book is 

 copiously illustrated with excellent photographs, and the printing and 

 binding are exceptionally good. A few obvious misprints occur, the most 

 common being the use of ". phenomena " for " phenomenon," and one 

 or two misspellings of " sync5^tium." The generic names, on pp. ix., xvi,, 

 and 59 among other places, would look better in capitals, which 

 are correctly adopted in other parts of the book for this purpose. 

 Altogether the book is a valuable and suggestive contribution to both 

 zoological and histological literature.

FOR LOCAL NATURALISTS. 



Faunistic Survey of Glamorgan. Instructions to Collectors. Cardiff 

 Xaturahsts' Society. 1920. Pp. 36. 6d. net. 



This useful pamphlet has been compiled by Dr. Jas J. Simpson, the 

 Secretary and Recorder of the publishing Society, ^^•ith the help of various 

 specialists. It gives in brief form much of the information on zoological 

 collecting contained in various pamphlets on special groups issued by 

 the British ^^luseum (Natural History). The immediate object is research 

 into the county fauna, and incidentally the enrichment of the local 

 collections in the National ^Museum of Wales at Cardiff. The instructions 

 for collecting specimens of various groups are clear and trustworthy, 

 and stress is wisely laid on the need of labelling with accurate notes as 

 to locahty, habit at, and date of capture. The public spirit of the 

 Cardiff Naturalists' Society is shown by the offer to supply copies of the 

 pamphlet at 6d. each to other societies, and we heartily commend this 

 generous action of our Welsh colleagues to the consideration of Irish 

 naturalists. 



PLANT LORE FOR THE YOUNG. 



A Book about Plants and Trees : a simple guide to Natural Study 

 for Boy Scouts and Girl Guides. By R. and S. G. Gurney. 8vo. Pp. 

 xiv., 103. C. Arthur Pearson, Ltd. 1920. is. 6d. net. 



This little book is designed to assist boys and girls to obtain the 

 " Naturalists' Badge " in the scout fraternity. It consists of short 

 chapters very simply written, introducing the juvenile reader to the 

 whole range of naked-eye botany. It is field botany mthout a lens and 

 \\ithout Latin names, and gives as good an introduction to the subject 

 as these severe restrictions allow. A proper breadth of view is main-
