At the meeting of the Club held on June 19th, 1908, Professor 

 E. A. Minchin, M.A., President, in the Chair, the minutes of the 

 meeting held on May 15th were read and confirmed. 



Messrs. J. E. Barnard, S. W. Flamank, G. Mitchell, H. V. 

 Knaggs, A. E. Auchley, N. T. Howard, J. H. Bayliffe, and 

 E. E. Banham were balloted for and duly elected members of 

 the Club. 



Mr. A. Earland exhibited some twenty-eight preparations of 

 Foraminifera. Some of the more noticeable may be mentioned. 

 A slide illustrating " triple isomorphism," of the imperforate or 

 porcellanous type, Comusjnra ; arenaceous, Ammodiscus ; per- 

 forate or hyaline, SpiriWina ; a preparation showing isomorphism 

 between an arenaceous and a hyaline form, Globigerina bidloides, 

 d'Orb, and Haplophragmiwm globigeriniforme, Parker and Jones. 

 Rhizammina indivisa, Brady, from the "cold area" of Faroe 

 Channel, 1,200 metres. This is one of the largest known forms. 

 The shell is built up of other Foraminifera (chiefly Globigerinae) 

 and sponge spicules cemented together. A slide of a number 

 of arenaceous forms from all parts of the world, was also ex- 

 hibited to show the great variety of materials used in the con- 

 struction of the composite shell or test, and the varying degree of 

 neatness in construction, which is principally due to the greater 

 or less amount of cement used by the organism. Crithionina 

 pisum, Goes, var. hispida, Flint. The typical form is found in 

 deep water, and builds a pea-shaped test of fine mud and sand. 

 The variety shown incorporates in its test sponge spicules always 

 with the points outwards, as a defensive measure against boring 

 annelids. A specimen of the world-wide form Ammodiscus in- 

 certus, d'Orb, from North Atlantic, was also exhibited. This 

 species ranges back at least as far as the Carboniferous 

 period. In describing an exhibit of specimens of Eeophax scor- 

 piurus, Montfort, it was stated that the " material on the spot " 

 was generally used in the construction of the shells of arenaceous 

 forms. The external appearance of individuals of the same 

 species may therefore vary greatly, according to the nature of 

 the surroundings. No sand being procurable, some of the 

 specimens shown had used other Foraminifera. Others from 

 shallow water in the North Sea used sand grains of various 

 sizes, and in one specimen garnets had also been found, [n 

 concluding his remarks, Mr. Earland expressed his thanks to
