EQUIPPING Of LflBORflTORY. 



In the equipping of a laboratory, one must necessarily be con- 

 trolled largely by the material and funds at their disposal, but a 

 few suggestions may serve to lighten somewhat the care of over- 

 seeing so much manipulation. 



Each student should be provided with a case made by boring 

 two rows of holes about 45 m. m. in diameter in a block of wood 

 30x14 c. m. and 45 m. m. thick. In this should be placed bottles 

 containing the more general reagents and stains that will be needed 

 frequently in the work. It is suggested that the set consist of 

 Iodine, Acetic, Sulphuric, and Hydrochloric acids, Glycerin, Potassic 

 Hydrate, Eosin, Haematoxylin, and Clearer. Another case contain- 

 ing reagents and stains of a more special nature can be placed on a 

 center table easily accessible to all. The desks should all be 

 equipped with wash bottles of alcohol and water, and a general 

 supply of the same agents should be located in a convenient place 

 in the laboratory. These arrangements will prevent the student 

 from being compelled to walk about searching for some reagent or 

 supply. Cases should be provided for containing the general store 

 of chemicals and glassware. The books should also be in a con- 

 venient place easily accessible to all. 



It is much more desirable that the microtomes, hardening and 

 infiltrating apparatus be on a special table which should also be 

 supplied with all the stains and reagents necessary for mounting 

 the sections. A convenient form of a waste vessel over which the 

 sections can be treated is made by fastening, with sealing wax, to 

 a tray or dinner platter, glass rods, parallel and about 4 c. m. apart. 

 The slides with the sections can be laid on these rods and treated
