It must be remembered that the figures in the attached table give means only, and that any registration over 75°F. Wet Bulb is high, and that at 80°F. Wet Bulb work becomes difficult. At 90°F. Wet Bulb the danger point is reached, and all work must cease on pain of death from heat apoplexy.
It will be seen, then, that Egypt is not especially hot, even from May till October, and that Helouan is particularly cool. These conclusions coincide with the feelings of those who live there. Alexandria is pleasant by day, because of the sea breezes, but at night most people prefer Heliopolis, which is drier and where they are more likely to enjoy a breeze.
These observations apply to the weather after May. From March to May the khamsin may blow for several days. The temperature then is high, but the air very dry. Khamsins usually cease in May.
Convalescent Hospitals
The Ras el Tin Convalescent Hospital at Alexandria was organised on similar principles to those adopted at Al Hayat, for those who required seaside change and sea bathing. At a later period half the accommodation in the Montazah Convalescent Hospital was rendered available to Australians. The Montazah Hospital will be described under the heading of Red Cross.
By the use of these three convalescent hospitals, accommodation was provided for 1,500 patients, but in case of necessity at least another 800 could have been accommodated. In addition a large convalescent camp was erected at Zeitoun in case of emergency. After the engagement in August, a very great rush of wounded was expected, and had the hospitals and convalescent homes been really taxed the convalescent camp would have been utilised for overflow purposes. Fortunately this did not become necessary, but the experience of May had given sufficient warning of possibilities.
The normal progress, then, of a patient admitted to No. 1 General Hospital suffering from a serious wound or a serious disease of non-infectious character was removal to one of the auxiliary hospitals when he reached the semi-convalescent stage, and removal to one of the convalescent hospitals when he reached the convalescent stage. From these hospitals he was discharged to duty.
