Medicines: Excellent lists of drugs suitable for the 

 tropics have often been written. One can hardly 

 do better than take one of Messrs. Burroughs and 

 Wellcome's 'Congo Chests.' I will mention one drug- 

 only, and that is Potassium Permanganate, as a remedy 

 for snake-bite. The method of using it is to open the 

 wound with a knife, and rub in the crystals of the 

 salt. As well as a considerable stock in my baggage, 

 I took a small capsule containing the crystals, which 

 fitted into the silver penholder that I always carried 

 in my pocket. It was ready for immediate use in 

 an emergency, but fortunately I never had need of it. 



A collapsible boat is a thing which I often wished 

 for ; I should certainly take one on another occasion. 



Photographic Work: Sanger-Shepherd and Co., of 

 London, who have had wide experience of tropical 

 photography, recommended me to take a Newman 

 and Guardia |-plate ' Reflex ' camera, fitted with focal- 

 plane shutter and Zeiss convertible Double-Protar 

 lens. This was carried in a leather sling case ; an 

 outer water-tight japanned box saved the instrument 

 from certain damage, when it was dropped by a native 

 one day into the Victoria Nyanza. Neither the rough 

 conditions of travel, the continued spells of wet in 

 Ruwenzori, nor the warm moisture of the Congo, 

 interfered with the efficiency of the camera, and a 

 spare shutter was never used. 



Paget XXXXX Plates (backed) were used, and 

 exposures were made in light metal single dark-slides, 

 which worked well and were easily carried. The 

 tropical conditions affected a few of the plates with 

 slight markings, which had to be 'touched out,' but 

 the majority of them gave good negatives. Sanger- 

 Shepherd and Co. packed the plates in sealed tins,
