ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 787 



Rabies. — The Government committee appointed to inquire into 

 the experiments of M. Pasteur, report that his statements have been 

 entirely borne out. Inocuhition with the attenuated virus of hydro- 

 phobia gives a dog immunity from the disease, just as simiLar treat- 

 ment preserves a sheep from charbon. All the 23 dogs submitted by 

 M. Pasteur as having been thus inoculated have resisted the strongest 

 virus on inoculation, whereas the majority of the 19 non-inoculated 

 dogs have succumbed. Of the latter, six were bitten by mad dogs, 

 three of them becoming mad, eight were subjected to intravenous 

 inoculation, all becoming mad, and five to inoculation by trepanning, 

 all becoming mad. The result is decisive ; but the committee will 

 now inoculate a large number of fresh dogs, and will compare these 

 with an equal number of dogs not inoculated. It will likewise investi- 

 gate the question whether, after a dog has been bitten, inoculation 

 with the attenuated virus will prevent any consequences from the 

 bite. 



Etiology of Tuberculosis.* — Dr. G. N. Sternberg has repeated 

 Koch's inoculation experiments, and is able to confirm him as to the 

 infectious nature of tuberculosis ; also as to the presence of the 

 bacillus discovered by him, in tubercle nodules in the lungs and in 

 tuberculous glands of inociilated rabbits and guinea-pigs (inoculated 

 with sputum containing the bacillus from a phthisical patient). 

 The experiments of Formad of Philadelphia, by which he claims to 

 induce tuberculosis in rabbits as a result of the introduction into the 

 cavity of the abdomen of finely powdered inorganic material, have 

 also been repeated, with an entirely negative result so far as the 

 production of tuberculosis is concerned. 



The conclusion is therefore reached that the bacillus of Koch is 

 an essential feature in the etiology of the infectious disease, tuber- 

 culosis. 



Bacteria and Minute Algae on Paper Money.f— J.Schaarschmidt, 

 in consequence of Prof. Eeinsch's discovery J of bacteria and algae on 

 coins, has examined Hungarian bank and State notes and Russian one- 

 rouble notes, and finds schizomycetes and algae on all of them even 

 upon the cleanest. 



The vegetation of paper money is, as the result of his researches, 

 composed of the following : Micrococcus, Bacillus, Leptothrix (various 

 forms), Bacterium termo, and Saccharomyces cerevisice. Also, very 

 rarely, Keinsch's Chroococcus monetarum and Pleurococcus monetarum. 



Grove's 'Synopsis of the Bacteria and Yeast Fungi.' § — This 

 book reaches us too late to say more than that it is a very handy and 

 well-arranged synopsis of the Schizomycetes and Saccharomycetes, 

 which cannot fail to bo of invaluable assistance to microscopists
