“…Putter (1909) referred at some length to studies on the teleost HeZiastes 296 c. BARKER J0RGENSEN which he believed had been demonstrated to live on DOM in the sea (the Mediterranean off Napoli). However, Lipschutz (1910Lipschutz ( , 1913, who continued the studies in Putter's laboratory, obtained no evidence for the utilization of DOM by the carp or eel larvae. He employed solutions of 10-100 mg/l of various organic substances of low molecular weight, such as tyrosine and glucose, or extracts of daphnians to mimic ' natural conditions '.…”

“…According to Putter (48,49) 1909 and 1914, it would be absolutely impossible that a sponge feeds on solid food only; on the contrary, it would be more likely that it feeds on organic substances in solution, which would be present in the water in (relatively) large quantities and would diffuse through its surface into its tissues. I shall not speak now about theto my opinion exactcritic on Putter's theory by Biedermann (6) and Lipschütz (40). I myself have never found a proof of its exactness during my investigations; on the contrary, the argument on which this theory its based (the deficit of solid food) seems rather not binding for the (green) fresh-water spongessee pag.…”

“…Sie sind durch vielleicht mangelhafte Fiitterung nicht so gut gewrachsen wie die Naturtiere, aber scheinbar gleichgross entwickelt. Scion Lips c h üt z bemerkt (13), "class Putters (16,17) Voraussetzung (gleichlange Tiere haben gleiches Gewicht and gleichen Stoffbestand) falsch ist. Durch Wagung und Ausmessung von aber hundert kleinen Moorkarpfen, die in einzelnen Gruppen gleichzeitlich gefangen waren, konnte gezeigt werden, dass bei gleicher Lange die g-rOssten Gewichtsdifferenzeu zwischen den einzelnen Individuen vorhanden sein kOnnen.`,` Also zog ich mOglichst gleichgrosse und gleichschwere Larven Da der Bewegungszustand bei beiden Tieren, im Leitungs-und Alkoholwasser, keinen merklichen Unterschied zeigte, scheint es mir, die letztgenannte MOglichkeit wohl fiir richtig zu halten."…”

“…der VerOffentlichung der von Putter (16,17) begriindeten Theorie von der Erniihrung der Wassertiere durch im Wasser gelOste Ndhrstoffe, ist dieses Problem von vielen Autoren vielfach umstritten worden. So bestatigten Wolff (20) an Simocephalus, K1-ene ekS7 (10,11,12) an Kaulquappen (Rana temporaria) diese Theorie, wdhrend K e r b (8) an Aalmont6e, Corthralarven und Plankton, Lip s c hiitz (13) an Karpfen und Aalmontee, und Bock (1) an Larven von Siredon zum negativen Resultate kamen; besonders tadelte der letztgen.annte Autor scharf die Arbeit Putters. E saki (4) hat die Kaulquappen (Bufo vulgaris japonicus und Hyla arborea japonica) durch verschiedene LOsungen z.B.…”
