employed in the appwrdls and basins. The waters of the 

 Augraben stream, which cross the grounds, are of very little 

 use. Nearly dry in summer, rapid and muddy after rain, 

 they have only hitherto served to supply some small exterior 

 basins. ■ Of course, different qualities of water are quite neces- 

 sary for the success of the experiments in acclimatisation 

 carried on so zealously at this establishment. Some fish delight 

 in a clear running stream, while others prefer to pass their 

 life in sluggish and fat waters. The engineering of the different 

 water-supplies, aU of them at different levels, has been effectu- 

 ally accomplished by M. Coumes, the engineer of this department 

 of the Bhine, who, in conjunction with Professor Coste, planned
