is also highly desirable. Professor Brewer thinks that the volume under 

 his charge will be ready for the press during the next year. 



7- ZOOLOGY. 



All that has been done in this department will be found further on, 

 under the heads of " Publications " and " Museum/' 



8. MUSEUM. 



The same statement has this year to be repeated which has already 

 been made so many times before. The collections of the survey are 

 large and valuable, but are exposed to loss by tire, and are placed where 

 there is no possibility of displaying them in a proper manner, or having 

 them open to the general public so as to form an attractive and instruc 

 tive exhibition. 



But considerable has been done within the past two years towards 

 getting our multifarious materials in order. A part of the minerals, 

 ores, and rock specimens, are laid out on shelves, so as to be examined 

 without difficulty. The fossils are arranged in handsome cases, and 

 named, so far as practicable, so that they can be consulted by students 

 in that department. The shells of the species now living on this coast 

 have also been very carefully arranged, named, and labelled, and can be 

 studied at all times by those interested in this branch of natural history. 

 The plants have been placed in cases, arranged in families and genera, 

 so far as known, and the specific names are added as fast as they are 

 received from the various authorities engaged in working them up. The 

 cones of all the pines, firs, and spruces, the seeds, fruits, etc., have been 

 arranged in drawers, as well as the cryptogamic vegetation so far as it 

 has yet been worked out. 



9. PUBLICATIONS. 



Since the last session of the Legislature, the following publications 

 have been issued by the Survey : 



Pala&ontolofjy < Vol. II, Section 1, Part 1, comprising the first instalment 

 of the Tertiary Invertebrate Fossils; by Mr. Gabb. This is accompa 

 nied by thirteen plates, which have been lithographed, and which will 

 soon be ready for delivery. The text is stereotyped. It is estimated 

 that the whole of this volume will be required for the remainder of the 

 Cretaceous and Tertiary invertebrate fossils. A third volume will con 

 tain the other Secondary and the Palaeosoic fossils, the plants, vertebrate 

 remains, and the microscopic fossils, the material for these researches 

 being already in the hands of eminent authorities at the East. 



Geographical Catalogue of the Mollusca found west of the Rocky Mountains j 

 by Dr. Cooper. This was prepared to facilitate the arrangement of the 

 conchological collection and for convenience in exchanging. It contains 

 the names and localities of eight hundred and twent} 7 -five species, so 

 printed that the catalogqe may serve for labels as well as for a check 

 list. 



Mining Statistics, No. 1, containing the quartz mines and mills between 

 the Merced and Stanislaus Rivers; by A. .Remond. 



In the zoological series the drawing and engraving for the volumes of 

 birds and fishes has been going on steadily, and that of the birds is 

 believed to be so nearly completed that the work can go to press imme-
