These tanks are so arranged in regard to level, that they have a fall from the highest Fig. to the lowest point of H inches in the feet, so that a change of water takes place, but so slowly as to be scarcely perceptible, e e shows leaden pipes leading water from the tanks to the bog department b b, which can be kept drier or moister by this means, as may be deemed expedient. M. Sckell has constructed his aquarium of oak posts and planks, a precau- tion rendered necessary to resist the severe frost to which the climate of Munich is liable. We have, how- ever, substituted pavement sides and bottoms for the tanks in our figure, as suiting our climate, and being more economical and durable. The bottom is well puddled before the pavement floor is laid upon it. The sides are formed of pavement set on edge, resting on the pavement 100 floor, and thoroughly jointed. At the ter- mination at / a waste-pipe is placed in the bottom of the tanks, and con- nected with an underground drain, so that the tanks may be dried when deemed necessary. From the section it will be seen that all these tanks are under the ground-level, a plan adopted to render them stronger, and more easily made water-tight. There is, however, an objection to this plan—viz., the plants are too far from the eye, parti- cularly those of smaller growth, which do not rise much above the surface of the w^ater. This might be easily remedied by forming the tanks upon the surface in- stead of under it; by this means the walks would be 2 feet under the level of the surface of the tanks and bogs, and the plants brought into a better position to be examined. In this case, the sides would require to be made of pavement 3 inches thick, and securely jointed at their edges, both for strength and for retaining the water. The form also might be im- proved by forming the tanks and bogs in concentric octagons round the basin a as a centre, leaving an open passage from the outer circl
