J. Engelbrechtitation. The feeling that these products are now too cheap for the good of future generations, that they are being selfishly exploited at too rapid a rate, and that in consequence of their excessive cheapness they are being produced and consumed wastefully has given rise to the conservation movement

A. Jeffrey,H. H. Daithe general welfare corresponds to the sale of everything at marginal cost. This means that toll bridges, which have recently been reintroduced around New York, are inefficient reversions; that all taxes on commodities, including sales taxes, are more objectionable than taxes on incomes, inheritance

V. E. Fridmanivate p:;tpers, correspondence and manuscripts to the Butler Library, Columbia University. This is a most appropriate place for them to reside, in that Hotelling‘s most productive period as an active researcher in eco­ nomics and statistics coincides with the years when he was Professor of Mathemati

A Variable Coefficient Version of Zakharov and Shabat’s Method: With Applications to the Integrationicient nonlinear equations. As an example, we show that if the variable coefficient b.(x,t) in their method satisfies the KdV equation ., then the nonlinear equation . is solvable through the inverse scattering transform by means of the extended procedure. We construct the one-soliton solution which

Steady Waves in Active Birelaxating Mediaequency relaxation being negative and a higher frequency one describing the absorption. In such a medium the change of the increment by the damping decrement takes place and under the definite relations between the relaxation frequency and the increment and decrement values, the existence of a stead
