INDEX GENERUM ET SPECIERUM ANIMALIUM. 195 
Index Generum et Specierum Animalium.—Report of the Com- 
mittee, consisting of Dr. HENRy Woopwarp (Chairman), Dr. 
F. A. BATHER (Secretary), Dr. P. L. ScuaTer, Rev. T. BR. R. 
STEBBING, Dr. W. E. Hoyne, Hon. WALTER ROTHSCHILD, and 
Lord WALSINGHAM. é 
Sreapy progress has been made with the literature for the second 
portion of this Index (1801-1850). Among numerous works dealt with, 
the compiler, Mr. C. Davies Sherborn, specially mentions the fol- 
lowing :— 
Publications of the British Museum. 
British Association Reports. 
H. G. Bronn’s works. 
Publications of the Academy of Brussels. 
Many editions of Buffon. 
“Isis ’’ (von Oken). 
Gesellschaft deutscher Naturforscher und Aerzte. 
As a matter of interest, it may be mentioned that 42,500 index- 
slips, in duplicate, have been made and arranged within the last two 
years. The Committee regards this as a surprising and satisfactory 
rate of progress, when it is remembered that it is entirely the work of 
a single individual. 
All the index-slips, as arranged up to date, are accessible for refer- 
ence in the library of the Geological Department at the Natural His- 
tory Museum, Cromwell Road, London, where they are frequently con- 
sulted by zoologists, both in person and by letter. Thus, as the value 
of the Index increases with its daily growth, the time of the compiler 
becomes more encroached on by inquirers. On the other hand, the 
diminution of the grant during the past few years has been seriously 
felt by the compiler, and the Committee, while recommending its own 
reappointment, asks the Association to consider carefully the value of 
- such a work of reference, and to give it the much needed help with a 
renewal of the grant of 1001. 
Haperiments in Inheritance.—Second Report of the Committee, 
consisting of Professor W. A. HrerpMaAn (Chairman), Mr. 
Dovctas Laurie (Secretary), Mr. R. C. Punnett, and Dr. . 
H. W. Marert Tims, on the Inheritance of Yellow-coat 
Colour in Mice. (Drawn up by the Secretary.) 
THE experiments discussed in my last year’s report are in progress. A 
detailed report would at present be premature. The Committee ask to 
be reappointed, with a grant of 301.
