For the purposes of excursions, congresses, lectures away from home, medical or veterinary investigations in the country, etc. it is often desirable to be able to carry Out microscopic investigations on the spot. The customary working microscopes, owing to their bulk and weight are scarcely adapted for being taken about on journeys and travels. Our travelling microscope has been specially designed for these purposes. The new model embodies further improvements in the matter of lightness and handiness. The weight of the instrument including the oak case with handle and leather strap is only 10 1/2 lbs. The stand conforms in its general contours to the modern Zeiss type and ensures perfect steadiness. It is inclinable and has an illuminating apparatus which can be raised and lowered. For convenience in folding the usual horseshoe foot is replaced by three hinged claw pieces.
