- Description: Goukamma Marine Protected Area (MPA) on the South African temperate South Coast has been shown to be effective in maintaining a spawning stock of roman, Chrysoblephus laticeps (Sparidae). The larval ecology and the oceanographic conditions in the area suggest a good potential for the enhancement of roman stocks outside the reserve through larval dispersal. A high rate of illegal fishing just inside the seaward boundary of the MPA could severely compromise its function.We suggest that a change of the seaward boundary of the reserve to coincide with a latitudinal line could increase its function as a harvest refuge for resident reef fishes such as roman, facilitate voluntary compliance and monitoring and prosecution of illegal fishing without a significant negative impact on the commercial linefishing fleet in the area. Simple adjustments such as the one proposed here could be attempted at a number of South African MPAs as they would be beneficial to achieve fishery and conservation goals alike.

- Description: To the Editor: The use of maggots to clean necrotic wounds, known as maggot debridement therapy (MDT), has long been known to the scientific world. Its use has been recorded since the 1500s when soldiers’ wounds were often infested with maggots. Napoleon’s surgeon, Baron Dominic Larrey, reported that wounds that were infested with maggots appeared to heal faster than those without maggots.1 William Baer is considered to be the founder of modern MDT. While treating soldiers in World War I, he noted the good condition of wounds that had been infested with maggots, and was the first doctor on record to experiment with the use of maggots in treating infections.1 MDT even featured in the recent version of the film ‘Spartacus’. Various species of flies have been used for MDT,1 the most commonly used being Lucilia sericata, a greenbottle blowfly (Figs 1 and 2). This fly is closely related to another greenbottle, L. cuprina, but L. cuprina feeds on live as well as necrotic tissue, which is undesirable in MDT. L. cuprina is commonly named the ‘sheep blowfly’ because it is responsible for fly-strike in sheep, a form of massive, usually rectal myiasis that can kill sheep. A recent article2 suggested that L. cuprina was being used successfully for MDT at the Eugene Marais Hospital Wound Care Centre (EMHWCC). As this would be inconsistent with international experience in MDT and at odds with the usual biology of L. cuprina, it was decided to check the identity of these flies.

Can shed snakeskin be considered to be a model membrane for human stratum corneum?

- Description: Recently there has been some interest in the use of shed snake skin as a "model" membrane for in vitro diffusion studies. Many different species of snake have been utilised as well as different skin sites (dorsal and ventral). The species is usually named and sometimes the skin site is indicated butsometimes neither species nor skin site is reported. Insome countries it is particularly difficult to obtain human skin for in vitro experimentation and it is therefore important to have alternate biological or synthetic membranes which mimic human skin membranes for diffusion experiments. In South Africa. shed snake skin is easily obtainable from the many snake parks present in the country. Since snakes moult periodically, a single animal can provide repeated sheds, thus reducing interindividual variability. Skins can be obtained without injury to the animal and do not have to be subjected to chemical or heat stress prior to use. The epidermis is shed as a large intact sheet, thus a single snake skin can provide multiple samples. Shed snake skin is not a living tissue, can be stored for long periods at room temperature and is easily transported. Stored and fresh snake skins appear to show no differences in permeability. Since snake skin lacks hair follicles,the problems associated with the transfollicular route of penetration, which may be significant in mammalian skins, can be avoided.

- Description: Jardine Correspondence transcribed by Jean Kelly August 2021. Transcription: Graham’s Town. May 1st 1864. [No salutation.] As I intend returning to England by the Mail Steamer which will leave Table Bay on the 20th June, I shall be much obliged to you, Walter, if you will plant the Ferns you have for me in a Wardian Case ready for their journey. I think they had better be put into the Wardian Case at once so that they may have taken good root before the time comes for closing the case. The case need not be closed till after I come down to Cape Town I expect to be there about the 13th or 14th of June. The last batch of Ferns I sent home were planted in rows, with thin boards laid along the top between the rows to keep the soil unmoved; and they reached home in very good order. I also want to take the Disa plants home with me. I am told that if they have died down, the bulbs had better be packed in dry sand; but if they have not died down, &* are still in leaf, they had better be planted in the case with the Ferns. If you have not got Wardian Case, which you can let me have, please ask Col. Travers to get one from Mr McGibbon at the Botanical Garden. Keep an account of any expenses you may incur, and I will repay you when I come down to Cape Town. I shall also be very much obliged if you could send me here some good Disa plants for the Botanical Gardens in this town, where they are very much wanted. They had better be packed in moss or dry sand, & put into a tin box, and then sent up by the post cart. If you should not be able to do this, or have any difficulties with respect to the Ferns, please write to let me know at once. Yours faithfully, Edmund R Wodehouse. Envelope addressed to: Mr Walter Jardine The Vineyard Claremont Cape Town. Pencilled note on envelope: Son of the Governor, Sir P Wodehouse.

I think that if you [?] choose first to damp them well with water it would make the earth more firm and stick closer to the roots – but you will understand best what to do.
