![No. XXVIII. OBSERVATIONS ON THE DEVELOPMENT OF THE MEDUSA.1 (extracted from the annals and magazine of natural history for JANUARY 1848.) The following observations were made upon three colo- nies of the larvae of a Medusa. One of these was procured on the 15th of September 1845, and the other two on the 11th of July 1846, adhering to the lower surface of stones in pools near low-water mark. The stones were of a size which readily permitted them to be conveyed home, where I have kept them up to the present time.2 The mode I have followed in keeping these animals alive is this. The stones to which they adhere are placed in vessels of considerable size, supplied daily with water fresh from the ocean, and the animals fed once or twice weekly with small morsels of mussels, which they readily swallow. The first of the three colonies consisted of between thirty and forty individuals, and the largest was between two and three lines in length; the individuals composing the other two colonies were more numerous and of somewhat larger size. 1 These observations were laid before the Literary and Philosophical Society of St. Andrews at the Meetings of the 4th of May 1846 and the 5th of April 1847, and abstracts of them were printed in the Transactions of the Society, and reprinted in Nos. 118 and 131 of the first series of this Journal. 2 [I have kept some of these larvae alive up to September 1848, when they were still in an apparently healthy condition.]](https://iiif.wellcomecollection.org/image/b21074008_0656.jp2/full/800%2C/0/default.jpg)
