Handbooh of Sanitary Information for House- 

 holders. By EoGEE S. Teacy, M. D., J 14 

 pp., 16°. ISTew York, D. Appleton & Co. 

 1895. Price, 50 cents. 

 This little book is intended especially for 

 the information of householders in the city 

 of New York, and is, in most respects, well 

 adapted to its purpose. The section on 

 house plumbing is the fullest and best. The 

 section on disinfection is behind the times 

 by about 12 years ; sulphate of iron is not 

 now considered to be a disinfectant, but 

 merely a deodorant, and no allusion is 

 made to the disinfectants now most relied 

 upon, viz.: chloride of lime, mercury bi- 

 chloride and carbolic acid. 



The warning against inhaling the breath 

 of persons affected with diphtheria and 

 consumption is unnecessary, and diverts 

 attention from the real source of danger, 

 which is correctly stated to be the dis- 

 charges from the throat, nose and lungs. 

 There are no bacteria, specific or other, in 

 the expired breath in ordinary respiration. 



SCIENTIFIC JOUBNALS. 

 THE AMERICAN GEOLOGIST, ,IULY. 



Remarks on the Genus Nanno, Clark. Hy Al- 



PHEUs Hyatt. 



This interesting genus of cephalopods 

 was first described by Professor J. M. Clarke 

 (Am. GeoL, Oct., 1895). The present au- 

 thor has made a more extended and de- 

 tailed study of the type specimens, which 

 were trom the Lower Silurian of southeast- 

 ern Minnesota. The paper is accompanied 

 by a half-tone plate showing several sec- 

 tions of the fossils. 



Steps of Progressive Research in the Geology of 

 the Lake Superior Region prior to the late 

 Wisconsin Survey. By N". H. Winchell. 

 This paper is the fifth in a series en- 

 titled ' Crucial Points in the Geology of the 

 Lake Superior Eegiou.' Beginning with 

 the Canadian Geological Survey, the vari- 



ous steps of progress are traced down to the 

 commencement of the Wisconsin Survey. 

 Among other things the origin and use of 

 the term Huronian is explained and some 

 misapplications of that term are noticed. 



Actinophorus Clarki, Newberry. By E. W. 



Claypole. 



The discovery of another specimen of this 

 fossil fish by Dr. Clai'ke, of Berea, Ohio, 

 after whom the fish was named, has fur- 

 nished Professor Claypole with data for a 

 morec omplete description than was possible 

 when the type was first described by Pro- 

 fessor Newberry. 



Camptonites and other Intrusives near Lake 

 Memphremagog . By V. F. Maesters. 

 Quite a number of dykes, both granitic 

 and lamphrophyric, have been found on the 

 shores of this lake. The following lamphro- 

 phyre dykes are described : Diabase, camp- 

 tonite, augite camptonite, monchiquite and 

 fourchite. An important feature of the pa- 

 per is a summary of the literature on other 

 occurrences of monchiquite and camptonite. 



The Kame-Moraine at Rochester, N. Y. By H. 



L. Faiechild. 



The Pinnacle hills, at Kochester, with 

 which this paper deals, have long been 

 known to glacialists, but no detailed de- 

 scription of them and of their origin has be- 

 fore been attempted, except by Mr. Warren 

 Upham, who regards them as of the nature 

 of eskers. Professor Fairchild has lately 

 investigated these hills, and the present 

 paper is a rather complete abstract of the 

 results of this investigation, which will be 

 published in fuU in the Proceedings of the 

 Eochester Academy of Science. He regards 

 these hills as constituting a kame series 

 forming part of a fi-ontal moraine. 



Under ' Editorial Comment ' a consider- 

 able review of the present status of the feld- 

 spars is given, and the results of the recent 

 optical work of Messrs Michel-Levy and La 

 Croix is brought forward. Under ' Corre-
