III. Astronomy. 



1. Total Eclipses of the Sun ; by Mabel Loomis Todd. Boston, 

 Roberts Brothers. 12mo, 1894, pp. 244. — This is a very pleasantly 

 written volume, designed not for astronomers but for those with- 

 out technical knowledge who are curious as to the strangely 

 impressive phenomena of total eclipses. It is profusely illustrated, 

 and professional astronomers will, we believe, find the little volume 

 not only interesting but useful, as it has an extensive index and 

 abundant references to original sources. 



2. Publications of the Lick Observatory of the University of 

 California. Vol. II, Sacramento, 1894. 4°, pp. 255. — This 

 volume contains Mr. Burnham's observations at Mount Hamil- 

 ton upon double stars made with the 36 inch and the 12 inch 

 refractors of the Lick Observatory between August, 1888, and 

 June, 1892. The six catalogues, Nos. 14-19, of new double stars 

 discovered by Mr. Burnham at Mount Hamilton, and originally 

 contributed to the Astronomische Nachrichten, are included in 

 this volume. 



3. Prof. M. Updegraff, who has had charge of the Laws 

 Observatory of the University of the State of Missouri at Colum- 

 bia since July, 1890, has communicated to the Academy of Sciences 

 of St. Louis a description of the building and principal instru- 

 ments together with the determination of the latitude, longitude, 

 and altitude above sea level of the Observatory. These are : 



Mean N. latitude, 38° 56' 5l"-70 ±0"-08 



W. longitude, 6 h 9 m 18 s -334 



Height above sea level, 737*41 feet. 



The equatorial telescope is a refractor of 7*45 inches clear 

 aperture, made in Munich, and used by Prof. Winlock at Shelby- 

 ville and at Cloverden. It has been provided with a spectroscope 

 by Fauth. The transit instrument has a clear aperture of 2'10 

 inches. 



IV. Botany. 



. 1. Guide to Sowerby^s Models of British Fungi in the Depart- 

 ment of Botany, British Museum, 1893. 8°, pp. 82. Figs. 93. — 

 This attractive pamphlet which is offered to the visitors of the 

 British Museum for the moderate sum of fourpence is intended as 

 a guide to the collection of models of edible and poisonous fungi 

 made by James Sowerby during the publication of his classic 

 work, English Fungi, 1797-1809. The collection was exhibited 

 to the public during Sowerby's life in his own house and after his 

 death it became the property of the British Museum. It con-
