PKOCEEDINGS OF THE SOCIETY.

fact was apparently overlooked tkat in every so-called cone of “ central 
light ” there was a large proportion of oblique light. 
Mr. Crisp also remarked that Mr. Smith, in pointing to the photographs, 
had said that “ anyone could see that the markings were perforations, 
and not beads.” It was, however, quite impossible for anyone to dis- 
tinguish between the two, by mere inspection, so readily as Mr. Smith 
seemed to think was possible. 
Mr. Smith said he would correct that statement at once, by saying 
that looking at the edge of a fracture anyone could see this ; he quite 
believed that by looking down upon the structure one could not tell 
which they were. 
The President said they were greatly indebted to Mr. Smith for the 
trouble he had taken to bring this matter before them. From his own 
point of view it was only by the continuous prosecution of the inquiry 
in this and in other ways, without any attempt at explanation, that gave 
promise of success, and if such demonstrations were steadily continued 
for some time longer they might reasonably hope for a solution. They 
had also to thank Mr. Smith for having given to them, in a permanent 
form, these records of what he had up to the present time accomplished. 
Mr. T- Charters White called attention to two slides which he ex- 
hibited. One of these he had called Ediinorhjncus, but since coming to 
the meeting he had referred to some authorities and had reason to think 
that this name was inappropriate. The object was an entozoon found in 
the large cockroaches which infested the sugar ships ; they were quite 
different from the ordinary kind, and were, he believed, known as Blatta 
germanica. In dissecting some of these he found a number of white 
particles which looked like eggs, each of which contained an embryo. 
He found altogether about 14, and having mounted them he had brought 
them for exhibition, and should be glad if anyone would tell him what 
they were. The other slide contained a quantity of bacilli from a urinary 
deposit. It was thought that the patient from whom they were obtained 
was suffering from hsematuria, and the urine was therefore carefully 
examined ; it was found to contain albumen, but no casts from the kidney 
could be seen. He took some of the deposited matter, and having stained 
it, found it to contain bacilli in enormous numbers, as would be seen in 
the specimen exhibited. He thought it might be of some interest, as 
bearing upon the subject brought up at the last meeting by Mr. Hall. 
Prof. Bell thought that the objects first mentioned by^J^.-'WEite 
were the cystic stage of some species of tape-worm. 
Mr. Michael believed that the cockroach desgftEed by Mr. White 
could hardly be Blatta germanica, which was rather than a large 
species, and was common in houses. It was^iq to be much less offensive 
than the ordinary species, and it was alsj^aid that, though common, the 
two sorts were not found in the same h^ises. 
Dr. R. L. Maddox’s Note on a^^all Glass-rod Illuminator was read, 
the note being accompanied by si^pijotographic negatives in illustration 
(sup’a, p. 101). /
