long ; it is covered hy six or seven rows of minute hooks 

 which decrease in size from the apex of the structure to- 

 ward the base. Owing to the thickness of the muscular 

 mass about the hooks and to their diminutive size, it was 

 not possible in the single specimen to determine exactly 

 their size and shape. One recognizes, however, witliout 

 ditficulty, the clear, highly refractive appearance charac- 

 teristic of such chitinous structures. The diminutive size 

 of the head led me at first to suspect that it was alto- 

 gether lacking in this specimen. It is probable that the 

 rostellum, with its mass of hooks, gives a firm hold on 

 the intestinal wall of the host, and the parasite may be 

 evacuated only with great difficulty. Accurate diagnosis 

 and records of methods employed in removing the worm 

 are necessary to determine the effect of the ordinary 

 remedies on this new species. It is by no means certain 

 that it will yield to the same treatment as the well 

 known species. 



A table of measurements for the three species of Taenia 

 which are found as adults in the human alimentary canal, 

 is appended for convenience in diagnosis. The measure- 

 ments for the familiar species are taken from Leuckart. 

 The specific name confusa is proposed for this new form:

Typhoid Germs in Ice. — The military officers at Rennes 

 (Medical Press and Circular) have recently suffered from 

 a typhoid epidemic, which has been traced to the ice which 

 was used to cool the champag-ne at a banquet. The ice 

 had been taken from a neighboring river at a point where 

 the town sewers empty.
