This paper exemplifies conservation through external sources in a developing country where internal sources can hardly meet the demands to safeguard their historic heritage. The paper draws attention to conservation activities of external sources in the heritage Stone Town of Zanzibar and unveils their influence on sustaining a built heritage. It was found that, external sources are instrumental to take the heritage to the world stage and play a significant role in revamping it from stagnant conservation. However, practices in the country render the ultimate results of these sources rather detrimental to warrant a sustainable effect.

Ovotestes found in a female intersex specimen of Rana limnocharis were reported. 1. In both gonads the ovarian tissue is pathological: all ova are degenerating, theca and connective tissue are hypertrophic and fibrous, and the presence of polygonal masses of pigment is remarkable. 2. Islets of testicular tissue are scattered on the surface of both gonads. A testicular nodule lies at the anterior end of the right gonad. Vasa efferentia are not present. The spermatogenesis is normal. 3. Oviducts are well-developed. Seminal vesicles are not present. Secondary male sexual characters such as nuptial color, thumb pads, protruded larynx and vocal sacs are clearly recognized.

More than 1, 500 frogs of Rana limnocharis were collected in Kumamoto district and used for a morphological study on the differentiation of their gonads. Results obtained were as follows: 1) Shortly after metamorphosis the gonads of all young frogs are of ovarian type in external appearance at least. But as they grow older, the gonads in about a half of them become testes, which are distinguishable macroscopically from the ovaries. This sex ratio is established at the end of the first year. 2) Examining the gonads microscopically at the end of metamorphosis, the gonads of the genetic males have a testicular structure, and in about a half of them the oocyte-like cells are present. 3) Although most of the oocyte-like cells degenerate during the first year, some of them remain and continue their growth in the following year. But they seldom attain about 150μ in diameter.
