Some Testimonials as to Physical Apparatus. 



Trier, 13 th April, 1911. 



1 beg to express my warmest thanks for the protecting 

 sheet for the Induction Apparatus as well as for the appa 

 ratus subsequently supplied. These are very well con- 

 structed and work faultlessly. 



Oberlehrer Reimann. 



Vegesack b. Bremen, 13 th April, 1911. 

 I beg to inform you that the consignment of appa- 

 ratus for teaching purposes, which arrived a few days ago, 

 has met with my entire satisfaction. 



Oberlehrer Dr. H. Kohlmann. 



Iterlin-Wilmersaorf, 14 th April, 1911. 

 I am very satisfied with the apparatus with which 

 you have supplied me. They can lay claim to the highest 

 precision and are characterised by thoroughness and 

 neatness of construction, thus affording great pleasure to 

 the eye. As a general rule these excellent qualities are 

 wanting in apparatus made by other firms. And no one 

 who has observed the steady perfection in construction 

 of Kohl's apparatus during the last few years can say 

 that the firm of Kohl has not endeavoured to establish 

 firmly its old and renowned reputation. 



Dr. Lotzbeyer, 



Oberlehrer an der Oberrealschule nebst 

 Reformrealgy mnasium . 



Gross- Lichterfelde, 14 th April, 1911. 

 You will also be glad to hear that nothing has gone 

 astray or become broken amon<r the 21 cases of apparatus, 

 and that we wonder anew at the beauty and practicability 

 of the apparatus.
