in order to ascertain the rate of the change which starch 

 solutions of definite strengths undergo when treated with 

 specially prepared diastase in the presence of various salts. 

 The work upon this subject is still incomplete. 



1897. Mr. F. P. ARMITAGE brought to a successful conclusion a 



redetermination of the atomic weight of Boron by a method 

 which had been attempted by the late Mr. HOSKYNS- 

 ABRAHALL, a former demy of Magdalen College.

 the Chemical Society, xiv. pp. 22-3, 1898. The full MS. of 

 this valuable work is preserved in the archives of the 

 Chemical Society. 



An examination of the absorptive power of volcanic tufa was 

 made by Mr. G ANTHER, and a chemical analysis of samples 

 of the same rock was completed by Mr. MANLEY.

1898. Summer. Mr. MANLEY ascertained the values of certain 



physical constants of samples of faulty rum for Mr. Veley.

The specific gravity of a sample of water brought from the 

 salt lake of Urmi in Persia by Mr. GUNTHER was accurately 

 determined by Mr. H. N. DICKSON, and the boiling-point, 

 refractive index, and saline contents of the same water were 

 measured by Mr. MANLEY.

1899. Summer Vacation. In order to ascertain whether the degree 



of salinity of a sea-water could be measured by an optical 

 test with as close an approximation as by the specific gravity 

 method, Mr. MANLEY examined some samples of sea-water 

 obtained by Mr. DICKSON.
