animals to Europe, and the many kinds which we have been 

 considering are thus carried from place to place without their 

 own guidance. Thus it is that the tropical faunae of the two sides 

 of the Atlantic so closely resemble each other. The Gulf Stream, 

 then, serves not only to modify the climate of naturally cold 

 regions, but also to distribute life equally on two different shores, 

 which, without some such communication, would have animals as 

 decidedly different as are those of Asia from American east coast 

 species. 



HUXLEY AND PASTEUR ON THE PREVENTION OF 



HYDROPHOBIA. 



AT the call of the Lord Mayor, a meeting was held at the 

 Mansion House, in London, on the 1st of July, to hear state- 

 ments from men of science with regard to the recent increase 

 of rabies in England and the efficacy of the treatment discov- 

 ered by M. Pasteur for the prevention of hydrophobia. Among 

 several letters that were read, the following, one from Prof. Hux- 

 ley and the other from M. Pasteur himself, are of especial interest : 



"Monte Generaso, Switzerland, June 25, 1889. 

 " My Lord Mayor : I greatly regret my inability to be pres- 

 ent at the meeting which is to be held under your lordship's au- 

 spices in reference to M. Pasteur and his institute. The unremit- 

 ting labors of that eminent Frenchman during the last half- 

 century have yielded rich harvests of new truths, and are models 

 of exact and refined research. As such they deserve and have 

 received all the honors which those who are the best judges of 

 their purely scientific merits are able to bestow. But it so hap- 

 pens that these subtle and patient searchings out of the ways of 

 the infinitely little — of that swarming life where the creature that 

 measures one thousandth part of an inch is a giant — have also 

 yielded results of supreme practical importance. The path of M. 

 Pasteur's investigations is strewed with gifts of vast monetary 

 value to the silk-trader, the brewer, and the wine merchant. And, 

 this being so, it might well be a proper and a graceful act on the part 

 of the representatives of trade and commerce in its greatest cen- 

 ter to make some public recognition of M. Pasteur's services even 

 if there were nothing further to be said about them. But there is 

 much more to be said. M. Pasteur's direct and indirect contribu- 

 tions to our knowledge of the causes of diseased states, and of the 

 means of preventing their occurrence, are not measurable by 

 money values, but by those of healthy life and diminished suffer- 

 ing to men. Medicine, surgery, and hygiene have all been pow-
