PKOCEEDINGS OF THE SOCIETY. 691 



in which the outer portions did not show depressions dotting the surface. 

 These were merely the small holes where the Crustacea had lived. 



Mr. H. B. Brady communicated to the Society a paper by the Eev. 

 Walter Howchin, of Adelaide, South Australia, " On some additions to the 

 Knowledge of the Carboniferous Foraminifera " (see p. 533). He said that 

 when he was working some years ago on his paper on Carboniferous Fora- 

 minifera, Mr. Howchin, then living in England, collected a number of speci- 

 mens ; shortly afterwards his health failed him and he went to Australia, 

 taking with him a large quantity of material to look through and examine. 

 The result was that about a year ago he sent over to England an elaborate 

 paper detailing what he had done. Situated, however, as Mr. Howchin 

 then was, without access to current literature upon the subject, he was 

 not aware of much which had been done since the publication of his 

 (Mr. Brady's) monograph. As it was not possible to present the paper 

 in its then form, he communicated with Mr. Howchin, and was asked in 

 reply to do what was necessary in the way of revision, and then to offer 

 it either to that or some other Society as he might think fit. As he felt 

 deeply grateful to the Royal Microscopical Society for the interest it had 

 taken in the Ehizopods and other subjects, he had great pleasure in pre- 

 senting the paper to them that evening. It formed a remarkably 

 interesting addition to their knowledge, and was well worthy of a place 

 in their Transactions. The most interesting thing to him was the fact 

 that many of these palaeozoic forms were identical with those dredged up 

 by the ' Porcupine ' and ' Challenger ' expeditions. 



Mr. Crisp said that, speaking for their Publication Committee, he 

 could only say they were very pleased to have the paper, and thanked 

 Mr. Brady for handing it over to them. His name was with every 

 microscopist quite a household word, and they were all very glad to have 

 that opportunity of seeing him with them. 



Mr. A. Frazer's improved form of microtome for objects imbedded in 

 paraffin was exhibited, the instrument being a modification and extension 

 of the Cathcart microtome. 



Mr. J. Mayall, Jun., referring to the new Nelson-Curties Microscope 

 for Photomicrography exhibited in the room, with the differential screw for 

 the fine-adjustment applied under the arm, said that the application of 

 the same thing to the substage, he might point out, was due to 

 Mr. Lombardi. This arrangement for purposes of photography was 

 extremely important, enabling the condenser to be adjusted with great 

 accuracy, without which the high degree of excellence shown in some 

 photographs could never have been obtained. 



With regard to the old Microscope before them, if his conjecture as 

 to its age was correct, this instrument would be of great interest as 

 enabling them to claim the so-called " Continental " form of fine-adjust- 

 ment, which was made upon exactly the same principle. 



The Chairman said that in adjourning to October he could only 

 express a hope that during the recess they would be able to collect 

 plenty of matter for the work of the next session, and that when the 

 time came for their next meeting they might have the pleasure of seeing 

 Dr. Hudson again with them. The Library would be closed from the 

 18th August to the 8th September inclusive.
