evidence to the fact that the archenteric canal for the greater part of its length 

 opens into the blastodermic cavity, and hence is confounded with it, owing to 

 the absorption of the " lecitho-enteric " plate, which is eventually split longitu- 

 dinally. The author summarizes his results by stating that the archenteric 

 canal appears as an early evagination from the archenteron, and, agreeing with 

 other mammals, the notocordal plate is formed from certain cylindrical cells of 

 the archenteric epithelium, not, as stated by Lieberskuehn and Koelliker, from 

 the whole median expansion of the archenteron. Figure A, a cross section, 

 shows on the median line immediately below the ectoderm a median plate of 

 larger entodermal cells continuous at each end with the general entodermic 

 layer, that is the notocordal plate. Below this is a small mass of cells which forms 

 the floor of the archenteric canal called the " enteric plate." This takes no 

 part in the formation of the notocord, but finally fuses with the entoderm or 

 •' lecithophore " below to form the alimentary entoderm or " lecitho-enterique " 

 plate. A. M. c.

able to entirely verify, it is probable 



that twelve men and sixty head of cattle died of anthrax in Pennsylvania during 



the year 1897. The men were, without exception, operatives from the tanneries, 



and the cattle were from pastures watered by the streams carrying off the refuse 



of these tanneries. 



In one of the cases, in a man who subsequently recovered, virulent cultures 



of the anthrax bacillus were obtained from the blood and eschar which marked 



the initial lesion of the man then sick. Virulent anthrax bacilli were also
