Dear Mr.. Wet more t- 
In response to your kind inquiry of December 10, please be informed that we are 
no longer in position to supply an iuativenin which would be of any value in the 
country that you plan on visiting. 
At one time, we did distribute a material in export under the title of Antivenin 
Ophidic, which was composed of equal parts of Bothropic and Cascabelj: but, our 
stock of this preparation has been exhausted for several months and manufacture 
discontinued. The only product that we now have available is Antivenin (Nearctic 
Crotalidae)* This is, of course, a lyophilized Antivenin; however, it is indicated 
only in the specific treatment of the affect of venom received from the bites of 
the North American Rattlesnake, Copperhead or Water Moccasin. 
We sincerely regret our inability to be of any assistance to you in this particular 
instance; however, we wish you to know that we do appreciate your interest in writ¬ 
ing us. 
Very truly yours.
