    Notes: Each contractile vacuole system of Paramecium multimicronucleata is made up of a number of components, some temporary and others permanent. The contracting vacuole with its membrane is a temporary structure as are the vesicles which fuse to form it. The vacuole discharges its contents to the exterior leaving a vestige closing the pore. The pore, with its discharging tubule and the feeding canals are permanent cell organelles. The feeding canals end in injection tubules which extend up to the pore. The vesicles, which later fuse to form the vacuole, are formed at the proximal end of the injection canals, leaving a membrane closing the canal, much as a food vacuole is formed at the gullet. The canal-fed contractile vacuole of Paramecium is very similar to the vesicle-fed vacuole of Euplotes both as to its origin and its fate. The Nassonov homology is rejected.

    Notes: 1. The prostomial glands, as described by Bourne, are deep-lying and unicellular, are distinctly different from the salivary glands, and their contents do not stain with boraxcarmine. They are ectodermal in origin.2. The material for the cocoon is secreted by the clitellar glands, while the prostomial glands secrete the yellowish plugs at the two poles which close the two ends of the cocoon.3. A fortnight after the cocoons are formed, the plugs become detached, leaving two outlets one at each pole, for the young leeches to wriggle out of the cocoon.4. The detachable plugs are possible only if not made of the same material as the cocoon.

    Notes: In Didelphis virginiana and Marmosa mexicana the retina is sauropsidan in type and the eye as a whole is markedly adapted for scotopic vision. The superior half of the fundus of Didelphis is occupied by a tapetum lucidum of the retinal type, formed by the enlarged pigment epithelial cells which are devoid of pigment and packed with reflective particles of unknown composition. Such a tapetum is unique among mammals - in all known sub-mammalian retinal tapeta the reflective material is guanin and is occusible in bright light by migratory fuscin. The retinal capillaries in Didelphis extend to the external limiting membrane, apparently in adaptation to the low permeability of the dense tapetum. Only four other mammals are known to have such capillaries and no inclusive explanation seems to hold for all. Didelphis possesses an ‘area centralis of sensitivity’ associated with the tapetum. Both genera have abundant rods and scanty cones, of three types. The oil droplets of the droplet-bearing single cones and the double cones are colorless and the double cone contains only one, not two as reported by O'Day for other marsupials; nor are the members of the double cone ever alike in size and form. Opossum double cones are thus perfectly orthodox; primitive placental mammals should be examined for double cones and oil droplets.

    Notes: 1. Der Abbau von Na2B4O7·10H2O schlägt, wie durch tensimetrische Messungen und durch Entwässerungsversuche über Trockenmitteln erkannt, je nach Vorbehandlung der untersuchten Präparate zwei grundsätzlich verschiedene Wege ein: Ein zuvor auf etwa 50° angetempertes Zehnhydrat geht in scharf ausgeprägter Stufe (10 mm isobar bei 20°) reversibel in kristallines Fünfhydrat über  -  „stabiler Abbau“  - , und dessen weiteres Verhalten entspricht ganz dem des oberhalb 60° aus Lösung kristallisierenden Pentahydrates. Frisch umkristallisiertes, „ungeschmortes“ Zehnhydrat hingegen wird bei gleicher Temperatur unter Entwicklung eines sehr viel kleineren Dampfdruckes, selbst nach langen Reaktionszeiten, zu einer viel wasserärmeren Stufe abgebaut. Der Bodenkörper zeigt bei einem Restgehalt von 5Mol H2O noch deutlich, bei 3 Mol und darunter abklingend die Interferenzen des Zehnhydrates neben zunehmend amorpher Beschaffenheit, die mit 2 Mol Restwasser praktisch voll erreicht ist. Dieser „instabile Abbauvorgang“ ist nicht reversibel; vorsichtige Wiederanwässerung der Rückstände aus dem Dampfraum oder auch leichtes Antempern der zwischen 10 und 3H2O liegenden Bodenkörper, etwa auf 50°, fuhrt diese „instabilen“ Abbausysteme in die „stabilen“ Verhältnisse über, d. h. veranlaßt  -  rontgenographisch festgestellt  -  die Bildung des Fünfhydrates.
