Large numbers of Culex pipiens, L., and C. salinarius, Coq., hatched 

 out about the middle of July from the polluted marshes of north- 

 western Newark Bay. The flights of C. pipiens from the breeding 

 places only ceased when these dried up owing to the weather and 

 additional drainage. A detailed account of the drainage work carried 

 out in 1914 is given.

 During 1914 cases of a disease having the characteristics of East 

 Coast fever were detected in Sudanese cattle. The disease always 

 declared itself within three weeks of the date of arrival. No cases 

 were found in Sudanese cattle which had been kept longer than that 

 period in quarantine. Systematic collection of ticks from the cattle 

 at various points on their journey showed that, even before arsenical 

 dippings were carried out at Haifa, the species of ticks capable of 

 carrying East Coast fever did not often remain on the cattle further 

 north than Luxor and were rarely found on arrival at Cairo. In 

 affected cattle, Koch's blue bodies were found in the spleen, lymphatic 

 glands, liver and kidneys. The author hesitates to diagnose the disease 

 as East Coast fever, on the ground that these bodies are apparently 

 not specific of this fever. In Egyptian fever, a disease affecting cattle, 

 bodies indistinguishable from Koch's bodies have been found, and 

 the disease at the same time presents peculiarities sufficient to 

 differentiate it from East Coast fever. A form of piroplasmosis occurs 

 in Sudanese sheep in which similar blue bodies are found. It has also 

 been encountered in Syrian and Egyptian sheep and has been reproduced 

 from the latter by blood inoculation into lambs. In the majority of 

 cases of Egyptian fever, the course of the disease resembles that of 

 Texas fever. Observations during the past three years show that the 

 disease is widespread in Egypt, being apparently more prevalent in 

 Lower Egypt, and occurring also among Sudanese cattle. Fatal cases 

 of Egyptian fever are rarely met with. The blood may show a heavy 

 infection, 80 to 90 per cent, of the corpuscles containing four or five 

 parasites each. Haemoglobinuria has been obsei-ved. Autopsy 

 shows minute ulcers in the intestine, enlarged lymph glands and 

 frequently an enlarged spleen. The species of tick associated with 

 outbreaks of this fever is Margaropus annulatus. 



Experiments on the subcutaneous injection of virulent cattle plague 

 blood to produce immunity were continued, with the result that doubly 

 inoculated cattle were proved to withstand the injection of doses 

 ranging from 2 to 10 cc. at periods of two and two and a half years 

 after the date of their immunisation. Up to the present no animal 

 has developed cattle plague out of 731 tested in the above way, although 

 some developed Texas or Egyptian fever.
