for the Anopheles Mosquito, to be filled up. Some hollows in rocks were 

 discovered containing about 18 in. of water filled with thousands of larva?. 



" The Hausas' and Carriers' lines were inspected twice a week, in 

 order to ensure no stagnant water being allowed to remain in old pots 

 or tins. The general result has been an immense reduction in the 

 number of Mosquitoes. With regard to my own quarters, in addition 

 to taking these sanitary measures, I had every Mosquito killed so far 

 as possible as soon as it appeared. The result of this was that my own 

 house was nearly free from Mosquitoes, and I have only had half a 

 day's fever during my time in Gambaga (nearly ten months). Whether 

 this immunity has been due to the absence of the Mosquito, I do not 

 venture to say." 



From East Africa the same excellent testimony arrives. Eeports 

 by various administrative officers are appended by Mr. Sharpe in his 

 report on the British Central African Protectorate. That of the chief 

 medical officer describes malaria amongst the Europeans as decreasing 

 on account of their care to protect themselves against Mosquito " bites." 



The Sea-serpent has again been sighted, this time on the Australian 

 coast, by the captain of the steamer 'Chillagoe,' belonging to the 

 Howard Smith Line (Melbourne). The ' Chillagoe ' arrived at Sydney 

 (N.S.W.), on July 13th, from Port Pirie (South Australia) direct, and 

 Capt. W. Firth supplied the fullowing particulars : — " On the passage 

 from Port Pirie to Sydney, when off Earn Head, a monster serpent was 

 seen by several members of the crew. Desiring to get a good view of 

 this monster, the ship's course was altered. Closer inspection proved 

 it to be an immense serpent of, as far as could be judged, from 30 ft. 

 to 35 ft., with four dorsal fins about 6 ft. apart, standing about 4 ft. or 

 5 ft. high. The head resembled that of a Seal, only it was much larger, 

 being about 2 ft. in diameter. When the ship approached to within 

 100 yards of the monster, it raised its head, looked at the vessel, and 

 disappeared. It was seen by myself, the second officer, and several 

 others. All agree that it resembled the serpent seen by those on board 

 the ' Princess,' illustrated in the ' Strand Magazine,' the only visible 

 difference being the fins, which seemed more angular than those in the 

 ; Magazine.' The body of the serpent did not appear above the water, 

 but it must have been of immense size."
