finest acoustical instruments in the world, but as an investigator 

 of great originality and distinction, and author of numerous me- 

 moirs on acoustics. In his atelier on the Quai d'Anjou he lives 

 and works in seclusion, surrounded by his instruments, even as 

 our own Faraday lived and worked amongst his electric and mag- 

 netic apparatus. Besides the great tonometer, his colossal master- 

 piece, Dr. Koenig's collection includes several large wave sirens 

 and innumerable pieces of apparatus in which his ingenious 

 manometric flames are adapted to acoustical investigation. There 

 also stands his tonometric clock, a time-piece governed, not by a 

 pendulum, but by a standard tuning-fork, the rate of vibration of 

 which it accurately records. 



The final chapters of the volume deal with " Manners and Cus- 

 toms of the Mchaves." by George A. Allen ; " Criminal Anthro- 

 pology," by Thomas Wilson; '■ Color Vision and Color Blindness,"' 

 by R. Brudenell Carter; "Technology and Civilization," hy F. 

 Reuleaux; the " Ramsden Dividing Engine," by J. E. Watkins; 

 " Memoir of Elias Loomis," by H. A. Newton; and a memoir of 

 '• William Kitchen Parker." The life and work of Elias Loomis 

 form no mean portion of the wealth of Yale University, and be 

 published 164 contrihutions to astronomy, meteorology, and other 

 branches of scientific research. He was a man possessed of con- 

 siderable scholarship, of positive convictions, and of a willingness 

 to follow at all hazards wherever truth and duty, as he conceived 

 them, might lead. Professor William Kitchen Parker was born 

 at Dogathorpe, near Peterborough. June 23, 1833, and died sud- 

 denly of syncope of the heart July 3, 1890. He was a fellow of 

 the Royal. Linnean. Zoological, and Royal Microscopical Societies ; 

 and honorary member of King's College. London, the Philosophical 

 Society of Cambridge, and the Medical Chirurgical Society. He 

 was also a member of the Imperial Society of Naturalists of Mos- 

 cow, and corresponding member of the Imperial Geological Insti- 

 tute of Vienna and the Academy of Natural Sciences of Philadel- 

 phia. In 1885 he received from the Royal College of Physicians 

 the Bayly medal, '■' Ob physiologiam feliciter excultam.'^ He was 



"an unworldly seeker after truth, and loved by all who knew him 

 for his uprightness, modesty, unselfishness, and generosity to 

 fellow- workers, always helping young inquirers with specimens 

 and information ; he was suddenly lost to sight as a friend and 

 father, but remains in the minds of fellow-workers, of those whom 

 he so freely taught, and of his stricken relatives, as a great and 

 good man, whose beneficent influence will ever be felt in a wide- 

 spreading and advancing science and among thoughtful and ap- 

 preciative men in all time." Mary Proctor.

Trees of the Northern United States. By Austin C. Apqak. 

 New York, American Book Co. 234 p. 12". $1. 

 The ground covered by this handy volume is the study, de- 

 scription, and determination of the wild and cultivated trees 

 found east of the Rocky Mountains and north of the southern 

 boundaries of Virginia and Missouri. Its author, who is professor 

 of botany in the New Jersey State Normal School, was evidently 

 governed in its preparation by the idea that, while it can hardly 

 be expected that the great majority of people will ever become 

 scientific in any line, it is jjossible to induce nearly every pupil to 

 become interested in and fully acquainted with such things, for 

 instance, as the trees of his neighborhood. The plan of the work, 

 therefore, is such as to first arouse the pupil's interest in the sub- 

 ject, and then to satisfy the consequent desire for information, 

 attention being mainly directed to the leaves, the wood, the bark, 

 and, in an elementary way, the fruit. These are the parts that 

 must be thoroughly known by all who wish to readily recognize 

 trees, and they, or most of them, may be found and studied 

 throughout the greater part of the year. Though the book may 

 be open to adverse criticism when viewed from the standijoint of 

 the advanced botanists, it should be borne in mind that it is not 

 written for them, but for the average teacher who has had no 

 strictly scientific training. We may add that the illustrations are 

 numerous and well adapted for the purpose in view.
