study purposes. The wings are removed from the body and 

 dipped in alcohol to soften them. A few minutes suffices. They 

 are then dipped in Labaraque solution until thoroughly 

 bleached. They are then transferred to alcohol to remove the 

 solution. Next they are transferred to a solution of eosin, a 

 crimson aniline dye. The time depends on the thickness of 

 the wing. When a proper tint is obtained the wings are laid 

 on microscopic slides with sufficient xylol balsam. A cover 

 glass placed above them gives a permanent mount. Large 

 wings thus mounted showed not only venation, but the circu- 

 latory tubes at junction point with body and the different 

 muscles which carry on the flight. 



Others explained that bleaching may be hastened by dipping 

 into dilute hydrochloric acid before the Labaraque solution. 

 Javelle water or a saturated solution of chloride of lime are 

 substitutes for Labaraque solution.
