The Baby London niicroscope is an ideal instrument for those who study nature, pond Hfe, etc. It can readily be carried in the pocket and is so easily set up that examinations can be made in the field with the greatest ease. It is also most useful to medical men for the carrying out of cursory examinations. It is extremely portable, and yet forms a complete and efficient microscope. It uses standard object glasses and eyepieces of all powers. All the necessary adjustments are provided, including sliding coarse adjustment and fine adjustment. There is a drawtube giving a varying tube length up to 160 mm. The case in which it is contained measures 5^ in. by 2| in. by 2 in. A complete range of accessories including substage condensers is supphed. The mirror usually suppHed with the microscope is concave, but when the instrument is fitted with a substage condenser, a flat mirror is provided. This can be supplied in place of the concave or as an extra, the mirrors being interchangeable in the fitting which carries them. To enable substage apparatus to be used a tubular fitting is supphed which screws into a thread in the stage. Two forms of substage condensers are supplied, the Abbe with iris diaphragm, and a combined condenser and spot lens. The latter is suitable for both transparent and dark ground illumination with low power object glasses. In order to obtain dark ground illumination with this condenser, a central patch stop which is attached to an arm is swung into position, thus an object can be easily viewed with transparent or dark ground illumination by merely swinging the stop in or out of position. The polariser of the polarising apparatus also fits into the tubular substage fitting, the analyser fitting over the eyepiece. For holding unmounted objects, there are supphed stage forceps and the cork object holder. The latter is suitable for examining fairly large flies, beetles, leaves, etc., the
