 „ „ Liquid Preservative. 



["It is frequently desirable to have a liquid preservative of the same 

 specific gravity as -water. Probably the nearest approach to such a 

 medium is the one recommended to be used with Deane's gelatin medium, 

 having the following composition : — rectified spirit 1| oz., water 1^ oz., 

 glycerin 5 fl. dr.]

 Hunter, W. — ^Recent Histological Methods. 



^Hardening. — (1) Weigert's rapid method in Miiller's iiuid, which is kept at 

 a temperature of 30°-40° C. accelerating the process from 6 weeks to 

 14 days. It is specially applicable to brain and spinal cord. (2) Gaule's, 

 placing the fresh tissue for 20-30 minutes in a saturated solution of 

 corrosive sublimate and then in alcohol. Imbedding in celloidin. Cutting. — 

 In cutting, the so-called dry method must be employed to obtain the full 

 advantages of this method. Staining in the ordinary way. Imbedding 

 in Paraffin, cutting and staining (alum carmine). For general purposes 

 celloidin will be found more generally useful than paraffin, especially for 

 nervous tissues. For fine histological or embryological purposes, paraffin 

 is by far the best, and can in no way be equalled by any other known 

 method.]
