Sanitary Notes 



BY 



The Dikectou 



We will now consider a little more in detail some of the subjects and problems 

 to which attention has been directed in a general way in the preceding paper. 



Following the course pursued in the last Eeport, attention may first be directed to the 

 meteorological conditions which have prevailed in Khartoum since these were last recorded. 

 The table has been prepared by Mr. J. A. Goodson, our Assistant Chemist, who has charge 

 of all the meteorological reporting work in Khartoum.

Eeference to the meteorological table given in our Third Eeport (j>age 63) will show 

 that Mr. Goodson's figures differ markedly from some there recorded and it is possible that 

 in the former table some errors, due to transcribing, occurred. Future observations should 

 clear up this point. The high total rainfall figure for January to July, 1910, i.e. 34-9 mm., 

 was almost wholly due to a single, prolonged and torrential shower in June. 



Mosquito Woek 



It is some considerable time since one submitted statistics dealing with the mosquito- 

 prevention work, although these have been carefully kept throughout. Now, however, 

 I submit two tables, one for Khartoum and the other for Khartoum North, which give Mosquito 

 figures for one complete sanitary year. These are most interesting and instructive, and, "tables" 

 though not absolutely indicative of the state of the town, are sufficiently reliable to give an 

 idea of what has been happening. 



The small receptacles mentioned comprise buckets, barrels, ice-chests, grindstone- 

 stands, small tanks, water-dishes in fowl runs, water jugs on dressing tables, flower 

 vases, bottles and small dishes of water placed beneath the legs of ice-chests, tables, 

 or food receptacles to check the depredations of ants. In the Khartoum North Table 

 the malign influence of the irrigated land there is noticeable. It will be seen how the
