THE GEOGRAPHICAL AND GEOLOGICAL DISTRI 

 BUTION OF ANIMALS. By ANGEI.O HEILPRIN, Professor 

 of Invertebrate Paleontology at the Academy of Katural Sciences, 

 Philadelphia, etc. 12mo. $2.00. 



&quot; An important contribution to physical science is Angelo Heilprin s Geo 

 graphical and Geological Distribution of Animals. The author has aimed to 

 present to hi* readers such of the more significant facts connected with the past 

 and present distribution of animal life as might lead to a proper conception of 

 the relations of existing fauna, and also to furnish the student with a work of 

 general reference, wherein the more salient features of the geography and geolo 

 gy of animal forms could be readily ascertained. While this book is addressed 

 chiefly to the naturalist, it contains much information, particularly on the sub 

 ject of the geographical distribution of animals, the rapidly increasing growth of 

 some species and the gradual extinction of others, which will interest and in 

 struct the general reader. Mr. Heilprin is no believer in the doctrine of inde 

 pendent creation, but holds that animate nature must be looked upon as a con 

 crete whole.&quot; Xew York Sun. 



MICROBES, FERMENTS, AND MOULDS. By E. L. TROUES- 

 BABT. With 107 Illustrations. 12nio. Cloth, $1.50. 



&quot;Microbes are everywhere ; every species of plant has Its special parasite?, 

 the vine having more than one hundred iocs of this kind. Fungi of a microscopic 

 size, they have their uses in nature, since they clear the surface of the earth from 

 dead bodies and fecal matter, from all dead and useless substances which are the 

 refuse of life, and return to the soil the soluble mineral eubstances from which 

 plants are derived. All fermented liquors, wine, beer, vinegar, etc., are artificially 

 produced by the species of microbes called ferments; they also cause bread to 

 rise. Others are injurious to us, tor in the shape of spores and seeds they enter 

 otir bodies with air and water and cause a large number of the diseases to which 

 the flesh is heir. Many physicians do not accept the microbian theory, consider 

 ing that when microbes are found in the blood they are neither the cause of the 

 disease, nor the contagious element, nor the vehicle of contagion. In France the 

 opponents of the microhian theory are Robin, Bechamp, and Jousset de Bellesme ; 

 in England, Lewis and Lionel Heale. The writer comes to the conclusion that 

 Pasteur s microbian theory is the only one that explains all facts.&quot; Xew York

EARTHQUAKES AND OTHER EARTH MOVEMENTS. 



By JOHN MILNE, Professor of Mining and Geology in the Imperial 

 College of Engineering, Tokio, Japan. With 38 Illustrations. 12mo. 

 Cloth, $1.75. 



&quot;In this little book Professor Milne has endeavored to bring together all that 

 is known concerning the nature and causes of earthquake movements. His task 

 was one of much difficulty. Professor Milne s excellent work in the science of 

 seismology has been done in Japan, in a region of incessant shocks of sufficient 

 energy to make observation possible, yet, with rare exceptions, of no disastrous 

 effects. He has haa the good fortune to be aided by Mr. Thomas Gray, a gentle 

 man of great constructive skill, as well as by Professors J. A. Ewing, W. 8. Chap 

 lin, and his other colleagues in the scientific colony which haa gathered about the 

 Imperial University of Japan. To these uentlemen we owe the best of our sci 

 ence of seismology, for before their achievements we had nothing of value con 

 cerning the physical conditions of earthquakes except the great, works of Robert 

 Mallet; and Mallet, with all his eenius and devotion to the subject, had but few 

 chances to observe the actual shocks, and so failed to understand many of their 

 important features.&quot; The Nation.
