Abstract
IN previous work it has been shown that the notochord of embryos of Rana esculenta L., which from the late blastula stage onwards have been kept in solutions of 0ยท5โ1 per cent sodium thiocyanate for 12โ48 hr., appear hyperdeveloped in comparison with the controls1. The same effect can be observed in embryos of the axolotl of Amblystoma tigrinum Green (= A. mexicanum Cope) and likewise in lampreys (Petromyzon [= Lampetra] planeri B1). A similar effect occurs under the influence of sodium iodide, vital dyes (pyocyanin, methylene-blue) and paranitrophenol2. Some details of the alterations in development produced by sodium thiocyanate are given below.
