On Dec. 14th Dr. A.-D. Milne, Principal Medical Olficer, 
took one of these tubes with him on a tour of inspection through 
sonie of the hottest parts of the Protectorate. The tube was car- 
ried in a tin despatch box on the liead of a porter in the sun, so 
that the test of résistance to high température was much more 
severe than in the laboratory experiments of Achalme and Marie 
Phisalix. Dr. Milne returned the tube to me unopened in April 
1910 and it remai ned on the laboratory table exposed to light 
and to the ordinary room température until the end of June. 
At that tinre Dr. Lowsley, Medical Officer in charge of the 
native hospital, Nairobi, most kindly undertook to try the vaccine 
in the gaol and lie vaccinated 107 prisoners taken at random. He 
reported that of these 107 vaccinations, 98 were successful. 
The next experiment consisted in sending some of this same 
Ivmph (préparée! in November 1909) to Marsabit, the station re- 
ferred to above. Mr. Cody, the Assistant Surgeon at Marsabit re¬ 
ported « the percentage of sucoess with the lymph you sent among 
the people inspectée! a week or ten clays after vaccination was 76. 
Out of one batch of children I vaccinated with the contents of a 
tube that had been opened 13 days earlier and then sealed, 9 we¬ 
re successful ». The difficulty of starting vaccination at Marsabit 
had accordingly been solved, thanks to Achalme and Marie Phi¬ 
salix. 
More recently a further trial has been made with this lymph, 
which had been kept at room température for 14 months, in com- 
parison with elrieel lymph sent from England and more recent 
lymph dried in a partial vacuum at the laboratory. Dr. Lowsley 
again carried out the trial, vaccinating 25 unselected cases in the 
gaol with each of the 3 strains mentioned. His results were as fol¬ 
io ws.

Ail these results appear to be a véritable triumph for the me- 
ihod of Achalme and Marie Phisalix. A part from the aclvantage 
of bein'g able to get active vaccine to distant and hot out-stations 
another use will be to stock ail outstations with this 
lymph, so that there shall always be ready to hand a sup- 
ply of vaccine which will not deteriorate sdriously though kept at
