28 ORGANIZATION AND BUILDINGS. 



than it would be in Western countries, because when the emer- 

 gency arises it is not possible immediately to procure the materials 

 necessary for the work. 



A large portion of the special apparatus has been mentioned in 

 the course of the description of the building, so that only a brief 

 review of the remaining equipment will be necessary. The labora- 

 tory is supplied with fifteen microscopes of the best pattern from 

 Zeiss, of Jena, and with two microscopes for travelers from Leitz. 

 All the necessary lenses to equip these instruments for ordinary 

 work are at hand, and in addition there are a certain number of 

 apochromatic 2-millimeter aperture 1.30 and 1.40 lenses. Ocular 

 and stage micrometers, Abbe drawing cameras, and other acces- 

 sories are of necessity a part of the equipment. The microtomes 

 were bought from Schanze, of Berlin, and are five in number, 

 besides which there are two Minot automatic instruments and one 

 using carbon dioxide for work with frozen sections. 



The incubators are of the manufacture of F. & M. Lauten- 

 schlager and are divided into two classes the portable ones for the 

 individual rooms and the larger ones. All the necessary apparatus 

 for work in preparing sections is also at hand. 



The museum is amply supplied with jars of all sizes, and the 

 storerooms contain the necessary surgical instruments, post-mortem 

 sets, and other appliances necessary for biological work. 



The chemical balances are of the make of Sartorius, of Goet- 

 tingen, and of Eueprecht, of Vienna. There is one precision 

 balance weighing to five kilograms and another to ten, to be used 

 in the standardizing of weights and measures. Both of these are 

 of the make of Sartorius. The laboratory has also a normal kilo- 

 gram and a normal set of weights from 500 grams downward from 

 Eueprecht, and a chief normal thermometer from A. Haak, of 

 Jena, from whom all of the laboratory thermometers have been 

 purchased. It is also provided with a complete set of normal 

 specific-gravity apparatus, alcoholimeters, and other appliances for 

 work with specific gravity. Apparatus for electric conductivity 

 measurements from Goetze, of Leipsic, has been purchased, as well 

 as normal volume measures from the same firm. An electric fur- 

 nace for 300 amperes current for obtaining high temperatures is 

 also a part of the chemical equipment. The necessary routine 

 apparatus, such as flasks, beakers, Petrie dishes, evaporating dishes, 

 platinum ware, retort stands, lamps, filtering apparatus, vacuum
