of the canines of lions shows a bimodaldistribution. Ewer's examination of sa-bertooth canines revealed no separationof sexes. The discussants concludedthat until more is known of the manysmaller felids, an understanding of mat-ing patterns in felids will largely bespeculative.

Propagation and management of cap-tive species is important to managers ofzoos. R. Thonmpson (University ofOklahoma and Oklahoma City Zoo) re-viewed reproductive success in captivecheetahs. Thompson's final consensuswas that until zoos publish the condi-tions associated with unsuccessful breed-ing attempts, it is impossible to deter-mine what factors, if any, favor suLccessin captive propagation.

Basing his models on extensive re-search with house cats, E. Colby (Dart-mouth Medical School) developedtechniques that enable him to artifi-cially induce estrus in the bobcat. Thishas opened the door to achieving rc-production by totally artificial meth-ods. S. Seager (Oregon Medical School)reported on his counterpart research incollection and storage of semen.D. Shorey and Eaton (World Wildlife

Safari) reported on the behavior andmanagement of Bengal tigers (Pantheratigris) in the first seminatural habitatdesigned for this species. The unsoci-ability of tigers was reflected in theirpartitioning of space. Of significanceto zoo management were the observa-tions of tigers daily eating grass, sug-gesting that zoo tigers may requiregrass on a regular basis.

In the more confined condition ofmany conventional zoos, stress is oftenexhibited by pairs of unsociable specieshoused together in the same cages.Apparent anxiety often appears in fe-males about to give birth, resulting inobstruction of proper maternal care.In an attempt to solve these and re-lated problems, J. W. Foster (WoodlandPark Zoo) conducted experiments usingPsymod, a mild tranquilizer. His dataare inconclusive, but it would appearthat Psymod is grossly superior toother tranquilizers in that it does notinterfere with feeding and drinking.The conference was sponsored by

World Wildlife Safari, Winston, Ore-gon, and Institute for the Study andConservation of Endangered Species,Athens, Georgia, and was held on 3 to5 May 1973 in Winston, Oregon.

"Versatile" is the only way to describethe new Wenking Potentiostats. Both the newHigh Power Model (HP-72, 200W output) andStandard Model (ST-72, 75W output) providethe flexibility of higher output voltage (atmedium current) or higher output current (atmedium voltage) simply by adjusting a multi-pin connector at the back of the instrument.

Additional new Wenking instrumentsinclude three economical PCA-72 PotentialControl Amplifiers featuring 3 superimposinginputs and grounded output. The PCA's can beused in combination with auxiliary equipmentfor the most advanced potential controltechniques. There are also new laboratorymodels, "fast rise" and high voltage models,scan generators, double pulse controlgenerators, a current/voltage integrator anda precision voltmeter.
