This early example of neural synthesis is a proof-ofconcept for how machine learning can drive new types of music software. Creating music can be as simple as specifying a set of music influences on which a model trains. We demonstrate a method for generating albums that imitate bands in experimental music genres previously unrealized by traditional synthesis techniques (e.g. additive, subtractive, FM, granular, concatenative). Raw audio is generated autoregressively in the timedomain using an unconditional SampleRNN. We create six albums this way. Artwork and song titles are also generated using materials from the original artists' back catalog as training data. We try a fully-automated method and a human-curated method. We discuss its potential for machine-assisted production.

10 mm. was saponified. The calculated percentage of acetic acid is 72.31; that found was 71.70. The mannide was prepared by the method devised by Liebermann (8). Analysis gave: C, 48.37 per cent; H, 7.32 per cent.The calculated values are: C, 49.27 per cent; , 6.90 per cent. The isomannide was prepared by Fauconnier's method (9). The compound melted sharply at 87°C. (uncorrected).The dulcitol employed was Pfanstiehl's c.p. product, m.p. 188°C., free from galactose. The dulcitan was prepared by Berthelot's method (10).Analysis gave the following composition: C, 43.79 per cent; , 7.20 per cent. The calculated values are: C, 43.87 per cent; H, 7.37 per cent.

Studies on the influence of mannitol and dulcitol and certain of their anhydrides on the dissociation of boric acid were reported in a previous communication (7). In general, the increased dissociation of boric acid produced by sugar alcohols was exhibited to a lesser degree or not at all by their anhydrides. Another series of these substances has been made available for study, and further investigations as to the effect of these compounds on the dissociation of boric acid have been instituted. MATERIALSThe-inositol, erythritol, pentaerythritol, and adonitol employed were Pfanstiehl's c.p. products and met the specifications of their catalogue.Ethylene glycol, ethylene oxide, propylene glycol, propylene oxide, and trimethylene glycol were supplied by the Eastman Kodak Co. The dihydroxyacetone employed was Oxantin, prepared formerly by Merck and Co. The epihydrin alcohol was prepared from epibromhydrin (1). The Z-epihydrin alcohol, distilling at 70°C. at 10 mm. pressure, was employed. The polygalitol was extracted from poly gala amara (9). The compound melted at 138°C. (uncorrected). The erythritan was prepared from erythritol by dehydration with sulfuric acid (2,6). Analysis gave the

In a previous communication (4) two of the authors (C. J. C. and J. C. K., Jr.) with Oakley studied the effect of the anhydrides of mannitol upon the dissociation constant of boric acid. Later the extraordinary potentiation of the dissociation constant of boric acid produced by a-mannitan was reported (1). Since sorbitan and isosorbide, the mono-and di-anhydrides, respectively, of sorbitol, were available for metabolic study, it was decided to determine the effect of these two compounds upon the titration curve of boric acid and to compare this with the influence of sorbitol.
