" June 20, 1917. Itigi. 



" We are having very cold nights now — quite delightful — 

 I pile on all my bedclothes at night and even then feel cold 

 in early morning. I believe we are about 5000 It. up here ! 

 [4278-2 feet. | 



" The party of Germans who were in the neighbourhood 

 are still uncaught, and leading us no end of a dance ! 



" I have been rather busy lately, as I have Smallpox to 

 deal with (as well as the usual Dysentery, Pneumonia and 

 Meningitis — I've got about 160 natives in hospital), and so 

 have been vaccinating and revaccinating all and sundry, 

 having to make a house-to-house visitation of the village 

 near here. Up to date not quite 20 cases — two (haemorrhagic) 

 died. 



" July 9, 1917. Iligi. 



" Still fine dry weather with cold nights. 



" Continuing on Smallpox, I had 19 cases, !> of which died, 

 one of them vaccinated and with a few pock marks on his 

 face from childhood. It seems to have been a very virulent 

 form. The last man to develop it was only vaccinated 5 

 months ago — true, he did not get very large marks. What 

 with Smallpox and Meningitis I've seen quite a lot of the 

 more interesting diseases. There is still Plague which 1 

 haven't met yet ! 



k " I am now rearing some Pierines from eggs, and have got 

 an egg from Piiiacopteryx simana, which is nice, as I presume 

 the larva must be undescribed, it having been so rare till 

 now that I have found it so abundant here. It has a well- 

 marked 'dry' form characterised by general suffusion with 

 hrowny grey scales beneath, so that resting among dry grass 

 it is very procryptic (as are other dry forms). Indeed I think 

 the explanation of the colours and shapes of dry Precis as 

 being procryptic receives great support from the marked 

 procrypsis of dry Pierines, Teracolus, for instance : the pink 

 or brown suffusion of the lower surfaces makes Teracolus very 

 hard to see among the pinks and browns of dry mass, when 



t he wings are closed.
