matter, and had promised to take photographs of the pictures. 

 They would readily understand that the plates should be of uniform 

 size and correct as regards details. The Photographic Society had 

 elected a Committee to attend to this matter, and it was proposed 

 that a Committee of the Philosophical Society should be appointed 

 to act with them. General Goodenough took great interest in the 

 subject, and had stated that the Eoyal Engineers had a photographic 

 apparatus which would be useful. It would be well also to appoint 

 some one interested in the Museum, and he thought they could 

 not do better than take the director of the Museum, Mr. Sclater. 



A Committee of five, which includes General Goodenough, Mr. 

 W. L. Sclater, Mr. H. G. Fourcade, and E. Marloth, was appointed. 



The President said he thought provision should be made for the 

 election of honorary members. He gave notice that he should move, 

 at the next meeting that honorary members may be elected in the 

 same manner as ordinary members, but not more than two in a year, 

 and not more than twelve altogether. 



It was decided to leave the question of numbers over for discussion. 



The Secretary exhibited a Sarcophagous fly that had been sent to 

 him by the Speaker of the House (the Hon. H. H. Juta, Q.C.), who 

 captured it at Caledon. This fly has no less than seven pollinia of 

 orchid affixed to its back. It is interesting to find that this fly 

 (Sarcophaga consoorina) is thus the means of occasional fertilisation. 

 The Hon. H. H. Juta informed him that he saw a great number of 

 these flies with the pollinia, but he could not see any orchid about. 



Dr. Corstorphine exhibited some Dwyka conglomerates showing 

 glacial action, discovered by Mr. Schwarz, of the Geological Com- 

 mission, north-east of the village of Ceres. 



Mr. Peringuey read some notes on a fly that is parasitic on 

 human beings as follows : In September, 1891, I brought to the 

 notice of the South African Philosophical Society an example of 

 dipterous — i.e., true fly — insect which was bred from larvae extracted 

 from the arm of a child in Natal, who turned out to be the child of 

 the Eev. C. Pettman, late of this city. I exhibited also the larva 

 of what I took to be that of a similar fly, which a friend of mine 

 had extracted from his own leg and sent me, with a very unpleasant 

 account of his sufferings. I received some time ago from Dr. H. P. 

 Veale, of Pretoria, also a larva extracted by him from the leg of one 

 of his patients. I could not, unfortunately, breed that interesting 

 specimen, but, on comparing it with the notes I made of the first 

 larva I obtained, I find that the two are identical, and are probably 

 the grub of the same fly that had attacked the Eev. Pettman's child, 

 and which I suggested at the time would, perhaps, prove to belong
