least sign of alarm. Why should the emanations of a cat be less alarming to this 
mouse than to any other? Is the tiger, our natural enemy—which, according to 
Prof. Jager, bears the same relation to us which a cat does to a mouse,—any more 
offensive to us than certain animals which never prey upon man at all, such as the 
polecat or the skunk? If the timid man tempts the dog or the ox to attack him, 
on what principle does he diffuse panic among his feliow-men? 
In short, Prof. Jager’s theory is beset with many and serious difficulties. 
Nevertheless, or, rather the more, we consider it entitled to a careful examin- 
ation, both as regards its conclusion and the phenomena upon which it is based ; 
the science of odors has yet to be constituted, and we are convinced that it will 
amply repay the needful trouble.—London Journal of Science. 
SCIENCE AND SPIRITUALISM. 
The recent publication of Professor Zollner’s work in Germany, the death of 
Serjeant Cox, a distinguished lawyer and spiritualist in England, and the extend- 
ed publication of Mr. Joseph Cook’s lectures in this country have manifestly 
awakened a new interest in the alleged phenomena of what is called ‘‘ spiritual- 
ism.” So many communications have come to us from all parts of the country, 
the writers earnestly inquiring ‘‘ why scientific men do not investigate the subject 
fully, and se¢7e it once for all,” that we are led to allude to the matter briefly. 
In the first place, we will say that scientific men ave investigated it, and 
published the results of their labors. In England, three representative men of 
the highest distinction, Wallace, the naturalist, Varley, the electrician, and 
Crookes, the chemist, have given the subject thorough experimental examination. 
Crookes devoted four years to the labor, Varley seven, and Wallace ze, and they 
state in the most decided manner that the alleged phenomena are actual and real. 
All these scientists are Fellows of the Royal Society, and they represent three of 
the most important departments of physical and natural science, chemistry, elec- 
tricity, and biology. In Germany, five of the renowned professors in the univers- 
ities, with Zollner at the head, have laboriously investigated the problem, and 
they also avow belief in the verity of the phenomena. In Russia, Wagner and 
Butleroff, professors in the University at St. Petersburg, after years of patient in- 
vestigation, have reached similar conclusions. In addition to those named above, 
Dr. Franz Hoffman, of Wurtzburg University, Camille Flammarion and Hermann 
Goldschmidt, distinguished astronomers, and a large number of other scientific 
men in Europe, noted for accuracy of research and great acquirements, render 
the same affirmative verdict. In this country, the late venerable Dr. Robert 
Hare, of the University of Pennsylvania, gave five years of experimental labor to 
the subject, and he also became a convert. With him may be counted, perhaps, 
twenty other students in science, of less note, who coincide in his views. 
Let us look at the other side. In England, three distinguished representative
