burg Med. Woc/i., publishes a case of this d'sease, with the results of 

 post mortem examination. He found marked lesions of the peripheral 

 nerves and in the voluntary muscles. As it is not the rule for either

 symptoms than is generally supposed. 



The Koch-Eberth Bacillus. — Apropos to the discussion about the 

 Koch-Eberth bacillus and its relation to typhoid fever, we suggest that 

 whenever a given disease represents broadly different varieties, the mi-

 which we call " gastric " and " gastro-intestinal .? " 



American Public Health Association. — The 19th annual meet- 

 ing will be held at Kansas City, Oct. 20-24, 1891. The local Com- 

 mittee of Arrangements announces that all the railway passenger 

 associations of the country have granted a one and one-third fare rate 

 for the round- trip on the usual certificate plan ; that is, procure a cer- 

 tificate of attendance from the agent at the starting-point by paying 

 full fai-e to Kansas City. 



Have the certificate of attendance signed by the proper officer of the 

 Association at Kansas City. This certificate will then procure return 

 ticket for one-third fare. All the leading hotels of Kansas City will 

 give special rates to delegates. Arrangements are being perfected for 

 an excursion into Kansas, as one of the features of the entertainment 

 of the Association. For any information as to the meeting, address
