For the particular purpose of detecting Trichinae we supply Stand IX with 

 specially constructed triple or double-lens objectives, so that by unscrewing one 

 or two lenses various magnifications result. The two equipments, mainly sufficing 

 for the above purpose, are as follows:

9205 Microscope for detecting trichinae I, with triple -lens objective 



and two oculars, resulting in six various magnifications between 



about 30 and 190 diameters 80. Pastailora 



0210 Microscope for detecting trichinae II, with double-lens ob- 

 jective and one ocular, resulting in magnifications about 40 and 

 100 diameters 65. Pastelada 



Both instruments satisfy the enactments in force for the German Empire 

 with regard to the inspection of carcases. No. 9205 has been specially recom- 

 mended by Prof. JOHNE of Dresden for the equipment of Inspectors for this disease. 

 See special prospectus relating to the microscope for the detection of trichinae. 



Hand Microscope. 



We supply a Hand Microscope (Fig. 26) suitable for class demonstration 

 The stage, with clips to hold the specimen, is fixed to the sleeve which receives 

 the body-tube. The instrument is focussed by altering the position of the tube 

 in the sleeve and after adjustment securing it by a clamping ring. Fine adjust- 

 ment is effected by drawing the ocular, which fits into the tube with a certain 

 amount of spring, in or out as required. In using the instrument it is directed 

 by hand towards a window or lamp.
