special measures have been adopted against Stegomyia fasciata, local 

 medical testimony in Central America agrees that yellow fever is dying 

 out, owing to the more rigid enforcement of quarantine measures. 

 This has happened at Caracas and Maracaibo. The conditions at 

 Guayaquil will remain very favourable to this disease until energetic 

 measures are taken against S. fasciata, which at present enjoys 

 unbounded opportmiities for breeding there.

In reply to a correspondent who suggested the possibility of ticks, 

 carried by birds, being responsible for isolated outbreaks of African 

 coast fever, the author states that, for the establishment of such an 

 outbreak the following conditions must be fulfilled : — The tick must be 

 picked up by a bird on the infected veld ; this tick must be capable of 

 transmitting coast fever ; the tick must not attach itself to the 

 temporary host, or its power of transmitting disease will be lost ; the 

 tick must be carried to a clean area and there dropped ; and it must 

 then attach itself to an animal susceptible to this disease. The chances 

 against the occurrence of this combination of circumstances are so great 

 as to remove it from the realms of probability, though the actual 

 possibility cannot be denied. Further, granted that the disease can 

 be thus transmitted, its prevention remains an impossibility, since the 

 birds cannot all be destroyed, neither can they be kept off infected 

 areas, nor can they be subjected to compulsory dipping !

Losses from trypanosomiasis have been less serious among native 

 herds than in previous years. A large percentage of military transport 

 cattle working on the Bukakata-Mbarara road became infected ; there 

 are no tsetse on this road, but it is possible that some of the oxen 

 became infected near Bukakata, where Glossina palpalis is found on 

 the lake shore. Oxen also died from the disease on the Fort Portal- 

 Mubendi road where there are no tsetse ; infection in this case probably 

 eame from some transport cattle sent from Kampala to Matiri, the
