is not witliout liop(! for the future. 'I'hns in 1907 we ag';iin received a special and much 
needed grant of £K 150 for hooks and periodicals. It is remarkahle how very little can he 
got for such a sum when the hack numbers of important journals are conceriKHl, hut still this 
grant has aided us very considerably and the library is at last approaching respectable 
dimensions. We are again indebted to the Department of Agricnltnre, D.S.A., and to many 
British, Colonial and Foreign schools and departments for literature on the varied subjects 
with which we have to deal. One takes this opjiortunity of thanking all those who have been 
good enough to send us reprints of their work. 
In one direction no real ])rogress can be I’eported. The Therapeutic (rarden mentioned 
in the First lle})ort has not proved a success. I'his is partly due to the I’act that it was 
founrl very difficult to obtain the reijuired seeds for })lanting, and that there has been no time 
to devote to wiiat looked like a promising scheme. True, we have a number of trees and 
shrubs which have grown at a phenomenal rate, hut few of them are of interest, and I think 
it will he found better to utilise the garden space in other directions, as imleed has already 
been done to some extent. It is doubtful if the indigenous medical plants of the Sudan are 
of sufficient value to justify the expcTiment. The attempt, however, has served to secure a 
useful plot of land and the cost has been trifling. 
In the Second Ileport one gave a list of soine of the subjects which would repay 
investigation. Amongst these were guinea worm infection and the therapeusis of 
Trypanosomiasis. So ra})id is the march of progress that much which was obscure about 
these two diseases has been cleared up, thanks in the one instance to the work of Leiper, 
and in the otlnu- to the researches of 'riiomas and Breinl, Ehrlich and Browning, Laveran 
and i\Iesnil, Koch and many others, llycetoma, which was also mentioned, has received 
attention from Brnmpt, whose studies have yielded valuable information. The laboratories 
have been unable to deal with any of these subjects fully, but with the increase of the 
staff and with outside aid one may hope to extend investigations and help in work which is 
for the good of humanity. Attendance at the Sleeping Sickness Conference in London 
impressed upon one the crying need for the rapid hut careful study of the diseases which 
tend to make parts of Africa uninhabitable alike for the black man and the white. There 
is much apathy amongst civilised nations, who will readily spend vast sums on all manner of 
objects but are too often blind and deaf to the claims of Science as a benefactor 
of mankind. Happily this cannot be said of the Government of the Sudan. Due has 
received constant support from 11. E. the Governor General, and it is again a pleasant 
duty to record the help and assistance rendered by many oflicials, and especially bv 
the Head of the Department to which the laboratories belong. Dn the part Jlr. Wellcome 
plays in the development of the work I need not dilate; it must be evident from a perusal 
of this introduction, which I would conclude by once more thanking the laboratories’ staff’ for 
their loyal assistance, and at the same time exjiressing our indebtedness to all tho.se who have 
kept our needs in mind.
