Research0a CINE-PHOTOMICROGRAPHY has for some time been
recognized as an extremely valuable and Fascinating factor in the fields oF research in medicine, bacteriolgy, biology, chemistry and all oF the natural sciences. Exploration into these fields by this method has been much hampered because equipment has been both expensive and diFficult to manage.
To meet the ever-increasing demand For a satisFactory Cine-Photomicro- 'graphic outfit, B & L has designed an apparatus which is low in price and simple in adjustment, yet it is as eFficient as a much more complicated and bulky set-up.
The outfit is so designed that you can Focus the microscope and ob- serve the specimen at any time without shiFting the camera or interFering. with the photographic process in any way. It can be used with any standard microscope.

INTERNATIONAL REVIEW OF SCIENTIrIC SYNTHESIS
Published every month (each number containing 100 to 120 pages) Editors: F. Bottazzi-G. Bruni-F. Enricques
IS THE ONLY REVIEW the contributors to which are really international. IS THE ONLY REVIEW that has a really world-wide circulation. IS THE ONLY REVIEW of scientific synthesis and unification that deals with the funda-
mental questions of all sciences: the history of the sciences, mathematics, astronomy, geology, physics, chemistry, biology, psychology and sociology.
IS THE ONLY REVIEW that by means of enquiries among the most eminent scientists and authors of all countries (On the philosophical principles of the various sciences; On the most fundamental astronomical and physical questions of current interest; On the contribution that the different countries have given to the development -of various branches of knowledge; On the more important biological questions; On the great economical and sociological international questions), studies all the main problems discussed in intel- lectual circles all over the world, and represents at the same time the first attempt at an international organization of philosophical and scientific progress.
IS THE ONLY REVIEW that among its contributors can boast of the most illustrious men of science in the whole world.
The articles are published in the language of their author, and every number has a sutpple- ment containing the French translation of all the articles that are not French. The review is thus completely accessible to those who know only French.

one generation will affect the happiness of the next. Not that appetite or intelligence is directly hereditary, but failure to balance the food supply properly may cause disease or catastrophe.
Neglect of the vitamines is unintelligent. Vitamine-B is essential to life.
Scientists have shown that nursing-young require more Vitamine-B than others. Cows' milk and human milk are low in Vitamine-B. This is repeatedly shown in medical journals.
It is a public responsibility to know this and to supply this Vitamine-B in one generation, for the benefit of the next.
Yeast Vitamine-Harris Tablets (rich in vitamines B, F and G) and Brewers' Yeast (Harris) Powder are prescribed by physicians for these purposes.
