crystals ; Johnstrupite, a titano-silicate of the cerium metals, 

 calcium, sodium, etc. ; it is allied to mosandrite, and near it in 

 crystallization ; Hiordtdahlite, a fluo-silicate of zirconium, cal- 

 cium, sodium ; it occurs in tabular triclinic crystals near wohlerite 

 in form ; Karyocerite, a silicate containing boron, thorium, the 

 cerium metals, calcium and others in smaller amount ; occurs in 

 rhombohedral crystals, tabular in habit ; Weibyeite, a carbon- 

 ate of the cerium metals near parisite. The descriptions of these 

 new species are models of thoroughness, and not less valuable are 

 the monographs on hydrargillite, the species of the thorite, sodalite 

 nephelite, mica, pyroxene, amphibole and feldspar groups, also 

 lavenite, leucophanite, homilite, acmite and segirite, and many 

 others. On the chemical side the author has had the assistance 

 of Professor Cleve and other chemists whose many careful analy- 

 ses add much to the value of the work. Mineralogists owe their 

 thanks not only to the author and those who have directly aided 

 him, but also to the editor and publisher of the journal of which 

 this work forms the sixteenth volume. 



5. Catalogue of Minerals for sale by George L. English & Co. 

 Philadelphia, 1890. — This catalogue contains a convenient list of 

 the species arranged as in Dana's System (with appendixes) and 

 including also others of recent date. The volume is issued in 

 attractive form and its value is increased by the republication of 

 a number of papers, with figures, on copper arsenates from Utah, 

 phenacite, bertrandite, etc. from Colorado, beryllonite from Maine, 

 and others. 



III. Botany. 



1. Catalogue of Plants found in New Jersey ; by N. L. 

 Britton, Ph.D., Trenton, N. J., 1889, pp. 642.— Dr. Britton, of 

 the Torrey Herbarium, Columbia College, published in 1881, a 

 preliminary Catalogue of New Jersey Plants, and, in 1888, in 

 conjunction with five associates, a preliminary catalogue of the 

 flowering plants and ferns reported as growing spontaneously 

 within one hundred miles of New York City. In the latter, the 

 nomenclature was revised and corrected by Dr. Britton and 

 Messrs. Sterns and Poggenburg. The present catalogue preserves 

 the nomenclature employed in the earlier work. To the lists, 

 Mr. Rau contributes the Sphagna, while the rest of the Bryophyta 

 have been arranged by Mr. Rau and Mrs. Britton, after the C. F. 

 Parker list. Mr. Rau has given also a list of Hepatic*. Dr. T. 

 F. Allen takes the Characese, and D. Eckfeldt the Lichens, basing 

 his enumeration on Professor Tuckerman's determinations of Mr. 

 Austin's collections. The catalogue of Mai'ine Algae is contrib- 

 uted by Mr. Martindale, and the Fresh-water forms by Rev. F. 

 Wolle, the two lists being combined by Dr. Britton into a single 

 series. The Diatoms are given by Professor Kain ; the Fungi by 

 Mr. Ellis and Mr. Gerard. 



From Dr. Britton's interesting tables we transcribe the follow- 

 ing data which possess much more than a local importance.
