MEMO: to Dr* Waldo Schmitt. 
IN REGARD: to obtaining leave of absence from Walter Reed 
Hospital for Roy Sexton, Jr*, to join the U* S # Smithsonian- 
Schmit t-Bredin Expedition to the Belgian Congo* 
\ 
A letter tP Colonel Kenneth F, Ernst, Chief Laboratory 
Service, Walter Reed ftpspital, from the Smithsonian would be 
all that is necessary he obtain official leave of absence for 
Roy, Jr* The sc ie" ^ ° of the expedition should be 
stressed with the 
microscopic photography, as 
well as field photography /being needed* 
Roy, Jr #l is told by his friends that there will 
\ 
be no difficulty in obt ainingXa leave of absence and, as I 
have already said, in case t h i s cannot be accomplished, he 
still has a leave due him which\he would take to go on the 
trip* I think that such a request should be put in whether 
he goes or not, since, if anything happened to me, such as 
a gall bladder operation or broken \e lb ow , and I were to be 
taken off from the trip the last mikute, there would not then 
be time to replace me with an alternate, unless this were done. 
Obtaining a general all around photographer of this type 
without payment of a salary in addition, to expenses would 
be somewhat difficult and I think the photographic part of the 
expedition is of paramount importance * 
V 
\ 
As mentioned before, Roy, Jr,, c au 1 d join the 
expedition at any day by plane and take o n 1 y\ a part of the 
time in case something unavoidably pulled me home* So I 
do think these preparations should be made, jug> t in case.
