were fatal. Subsequently, Dr. Orth inoculated a rabbit with 

 the fresh blood of the second case, and from this one another, 

 and so on till eight were injected. Masses of bacteria were 

 found in the blood and connective tissue of all these ani- 

 mals. 



In the May number of the Monthly Microscopical Journal 

 we find an interesting communication from Dr. D. H.Schmidt, 

 of New Orleans, on "The construction of dark or double- 

 bordered Nerve Fibre;" the paper is illustrated by three 

 plates, and upon the whole confirms Max Schultze's discov- 

 ery of the fibrillous structure of the axis cylinder, differing, 

 however, in this, that whereas Schultze considered the fibrils 

 smooth, Schmidt finds them to consist of minute granules 

 about ttutj millimeter in diameter, arranged in regular rows, 

 and united by a homogeneous inter-fibrillous substance. One 

 is reminded of Mr. Slack's resolution of the hitherto consid- 

 ered smooth pinnae of Pinnularia into a granular structure, 

 and also of Dr. Pigott's "Podura beads." All these appear- 

 ances are produced by the use of extreme oblique light, and 

 we are by no means convinced that they indicate the true 

 structure. 



ETHNOLOGY. 



Progress in Anthropology and Ethnology has been in three 

 directions : 



1. There has been a more thorough and systematic method 

 of observation on the field, a more scientific classification of 

 the material, and a multiplication of societies and periodicals 

 for the purposes of study and popular instruction. 



2. A great increase has taken place in the number and 

 thoroughness of investigations in drift gravels, caves, pala- 

 fittes, kjokkenmoddings, mounds, tumuli, shell -heaps, and 

 among the ruins of buried cities, etc. 



3. Our knowledge has been greatly extended of the tribes 

 of men now living on the earth, whose structure and objects 

 of culture throw light upon the history of mankind, in all 

 ages of the world and in all conditions of society. 



An interesting lecture on anthropology, by Dr. G.Thanlow 

 Kiel, appears in Zeitschrift filr Ethnologic, petting forth the 

 design and scope of the orders issued to officers of the Navy 

 by the chief of the German Admiralty, at the instance of the
