PAGE, continuous

This test consists of two parts. Part A consists of 15 numbered circles distributed over a white sheet of paper. The child is required to connect the circles with a pencil line as quickly as possible, beginning with circle 1 and proceeding in numerical sequence. Part B consists of 15 circles numbered from 1 to 8 and lettered from A to G. The child is required to connect the circles, alternating between sequences of numbers and letters. Two scores are recorded - the number of seconds required to finish each part and the number of errors. This test appears to require immediate recognition of the symbolic significance of numbers and letters, ability to scan the page continuously to identify the next number or letter in sequence, flexibility in integrating the numerical and alphabetical sequence, and completion of these requirements under the pressure of time. 

It is regretted that the size of the volume has rendered the insertion of literature references impossible the Selected Bibliography (A,5) may partly compensate for this omission. Section numbers are now included in the headings of the pages—a feature introduced in response to requests by many readers. The volume comprises virtually at least three books under one cover, viz., experimental technique, preparations, and qualitative organic analysis. It should therefore continue to be of value as a one volume reference work in the laboratory. Students at all levels will find their requirements for laboratory work (excluding quantitative organic analysis) adequately provided for and, furthermore, the writer hopes that the book will be used as a source of information to supplement their theoretical studies. 

Note. Insertion of fif after a page number, for example 314fif, means and following, and indicates that a reference continues, in the same context, on following pages. If the reference continues on adjacent pages, but in a different context, fif is not attached for example 320, 321 indicates references to the same atom or molecule but in different contexts.
