Dear Alex: 
October 9, 1946. 
I am trying to jot down a few of the drugs which will probably be 
of use to you on your next expedition. I thought I would send you this list 
so that you can pick up the necessary articles at your convenience. 
ATABRINE I would .suggest that you take 100 tablets of Atabrine 
grains 1§. They are very useful particularly if you are going to trea + the 
natives. Most of them usually have malaria. If you are going to be in a 
malarial country I have always found it very helpful to take 1^ grains of 
Atabrine at least once a da.y for three days and then skip two or three days. 
This will maintain sufficient concentration in the blood which 1 believe 
destroys parasites. 
YATREN Yatren is a drug put out by the Winthrop Chemical 
Company as is also the Atabrine and is very useful in the treatment of dysen¬ 
teries. One can take three to eight tablets daily depending upon the severity 
of the condition. One tablet daily has been recommended as a prophylaxis. 
They contain a form of iodine that is good, for ones system. In case you are 
not able to get Yatren, Lilly puts out a preparation which is similar called 
Cheniofon. These are the two most important drugs to have in vour equipment. 
SULFADIAZINE I would also recommend taking Sulfadiazine tablets 
grains or l/S gram. These s.re good usually in cases of severe infections 
such as septic wounds, blood poisoning, abscesses and upper respiratory in¬ 
fections which might go on to a severe bronchitis or pneumonia. The usual 
dosage is two tablets or one gram every four hours and it is best to give 
about lOg'rains of sodium bicarbonate with each dose and plenty of water 
should be taken during the interim. 
TINCTURE METHIOLATE You should also take a pint or less, depend¬ 
ing upon the kind of cases you might have to treat, of Tincture Methiolate (Lilly) 
It is a good idea to have one of their little glass dispensers to carry in your 
pocket. 
BD SNAKE PIMP If you are in any region where there are poisonous 
snakes be sure to carry a BD snake pump. This is a small package about three 
inches long by two inches in diameter and may easily be carried in your pocket 
at all times when in the field. It is important to always remember to put a 
tourniquet on first and then apply the suction pump according to directions. 
One should never walk anv distance or take any alcohol after a snake bite. Thev 
should remain quiet and after the poison has been suctioned for several hours, 
relaxing the tourniquet every now and then to relieve some of the congestion of 
the affected limb, a saturated solution of salt and water should be applied and * 
kept over the area for another twenty-four hours. Magnesium sulphate also may 
be used for this purpose.
