“The artificial lake at the mouth of the Sutro Tunnel swarms 
with fish from three to four inches in length. They were planted 
in the lake by some Indians about fifteen months ago. They have 
increased at a wonderful rate, and there now appear to be millions 
of them. These fish are likely to find themselves in literally hot 
water when pumping from the flooded mines has been commenced.” 
— We have received the fourth, fifth and sixth plates of Leuck- 
art and Nitsche’s Zoologische Wandtafeln ; these diagrams illus- 
trating the structure of different types of the animal kingdom. 
Each diagram is a lithograph, costing in Germany from eighty pfg. 
to at most two marks. They are thus cheap, and on the whole 
most excellent, and will prove serviceable in schools and colleges. 
The present diagrams represent the Crustacea and the anatomy 
of the living crinoid Rhizocrinus, This is a most valuable dia- 
gram, and very cheap. The sixth represents the metamorphosis 
of the potato beetle, Doryphora 10-lineuta, and is not particularly 
well done. One of the figures is not accurate, nor is the beetle 
sufficiently typical of the Coleoptera, to be selected as a subject 
fora diagram. They are published by Theodor Fischer, but can 
be imported, we suppose, through B. Westermann Oy 524 
Broadway, N. Y., or any other importers of German books.
