ON THE STUDY OF SOLUBILITY PHENOMENA. 111 
Preliminary trials have been made to ascertain the influence of 
isomeric alcohols on the solubility of salts in water at 25°C. Small 
differences have been observed in the precipitating effect of the butylic 
alcohols, and work is now in progress to determine the variations in 
solubility of the chlorides of potassium, sodium and ammonium brought 
about by the addition of small quantities of the isomeric propylic, 
butylic and amylic alcohols. 
It is desired that the Committee be reappointed. 
Erratic Blocks of the British Isles —Report of the Committee,

Hitt, J. W. StatuHer, and J. H. Mitton. 
Tur Committee reports that owing, probably, to the early date of 
the meeting no lists of erratics have been contributed during the year, 
and in consequence no part of the grant has been expended. 
The Committee seeks reappointment with a grant of dl. 
The Preparation of a List of Characteristic Fossils.—Second 
Interim Report of the Committee, consisting of Professor P. 
F. KENDALL (Chairman), Mr. W. LOWER CARTER (Secretary), 
Mr. H. A. ALLEN, Professor W. S. Bouuton, Professor G. 
Cots, Dr. A. R. DwEeRRYHOUSE, Professors J. W. GREGORY, 
Sir T. H. Hoxtuanp, G. A. Lepour, and §. H. REYNOLDs, 
Dr. Mariz C. Stopes, Mr. Cosmo Jouns, Dr. J. E. Marr, 
Dr. A. VAUGHAN, Professor W. W. Watts, Mr. H. Woops, 
and Dr. A. SMITH WooDwaRD, appointed for the considera- 
tion thereof. 
No meeting of the Committee was held during the year, but numerous 
suggestions for a list of fossils were received. From these a provisional 
list was compiled by the Secretary, and uncorrected were printed and 
circulated. This provisional list, when revised, will, it is hoped, form 
the basis for the publication of an amended list of fossils next year. 
The Committee ask for reappointment with a grant of £10.
