Yothers inc. Griffin (l60) in 1940 reported tests made vrith insecti- 
cides upon the r/ooll;^'- ijTole ap".:id, j ^riosom r. Irniger'jn (Hausm.;, and the 
green apple aphid, A-phis poai Leg., at "'eno'-tcliee , Wash., diaring 1931 to 
1933. 
The results of these tests indicate the follov/ing conclusions: Ana- 
oasine sulfate and nico-cine sulfate cxe, at the greatest dilutions 
tested (l:4800), ahout equal in effectiveness against "both the rroolly and 
the green aphids. 3ach gave approximately 97 percent kill of the woolly 
aphid at the above dilution used with an all^^lated naphthalene sulfonate 
as a wetting agent, inclusive of 58 percent killed oy the latter alone. 
Somewhere "between a dilution oi 1:3200 and 1;4800 ooth analoasine sulfate 
and nicotine sulfate, even with the \;stting agent douhied, "begin to fall 
off from 100 percent kill of the woolly aphid. Gomenhfcre "between the 
same dilutions they also "begin to fall off from 100 percent kill of the 
green aphid, with sodium oleate as a wetter j "but with the wetter not in- 
creased at ti..e greater dr'luticr,, as is the case vrl th the- ;roolly aphid. 
Against the green apple ap'nid nicotine ond ana"bac'jne siilfate ^7ith acces- 
sory agents gave alinost complete mortality up to dilutions of 1:3200, and 
the anahasine gave 95 percent kill at 1:4800.

ICatznel'son and Ka"bac"hnik (53) in P-ussian patent 39.108, issued 
Octo"ber 31, 19*54, d&scriue a prccest; of making a;:r*.noana"basine "oy heat- 
ing ana'basine wifh amides jf alkali metals in the presence of organic 
solvents. 3fimov (21) in ".ussian patent 40,355, issued December 31, 1934, 
descri"bes a process of m;?i.'.ng nicotir3 and ana'basine sulphites "by treat- 
ing the alka,loids with S!-.j.phurou3 a.ci d. 
Dashicevich (20) in Russian patent 47,865, issued July 31, 1936, de- 
scri"bes the preparation of salts of ana'basine for use as insecticides. 
Anabaslne is treated in a solution or directly with \7e£irr acids or their 
anh;'c"!j-ides, e.g., hydrogen sulphide or car'oon dioxide, and the salts 
formed are separated from the solution. 
Sokolov and Kretov (143) in Itussian patent 51,137, issued Hay 31, 
1937, describe the preparation of anabasine fluosilicate ^oy treating a solu- 
tion of anabasine or its sulfate consecutively'- v/ith fluosilicic acid and 
ethyl alcohol or methyl alcohol. 
Smith (139) in United States patent 2,033,855, issued IXarch 10, 1936, 
applied for Julj- 5, 1934, claims the method of preparing organic base- 
bentonite compounds, which comprises bringing to^'efner, in the presence 
of water, bentonite and organic bases of sufficient alicalinity to be 
titrat-able with mineral acids. Anabasine is mentioned as a base thr.t 
reacts readily with bentonite.
