i6 THE MICROSCOPE. 



Fig. 12. One, of only two, seen edgeways, after contraction had 

 ceased. Notice conformation at c. in reference to internal mass. 



Fig. 13. A diagrammatic section of the "Homogeneous mass theory" 

 which has been taught me up to date. 



Fig. 14. Diagrammatic section of "Old Cheese theory" — homogeneous 

 mass of increasing density. 



Fig. 15. Diagram of what this case has forced me to beHeve, viz.. 

 That the red corpuscle of human blood is a semifluid homogeneous (?) sub- 

 stance b. enclosed in an investing membrane or sac c, and containing a 

 nucleus a, and in some cases (rare) a nucleolus also. 



Fig. 16. A cross section of No. 15, like letters referring to like parts. 



Fig. 17. Diagram after contraction and differentiation, probably caused 

 in this case by the chemicals in addition to the alcohol, used in coloring 

 and flavoring certain so-called whiskies — b. the mass contracted, leaving 

 d. transparent, revealing a double contour at c. 



Fig. 18. Cross section of diagram No. 17. 



REMARKS. 



The color of the corpuscles before contraction was a reddish-brown and 

 not what I consider normal ; viz., a yellowish-green (delicate tint), with a 

 breath of blue and violet playing over them. After contraction the space 

 between a. and c. was transparent at d. See corpuscle No. 11 in connec- 

 tion with diagrams 15 and 17, as number twelve was the most absorbing 

 view I've ever had with the microscope, and while admitting that I was 

 more especially interested in this case orptically, can but think it worthy 

 the consideration of the Pathological Microscopist. 



The drawings are faithful representations of that which "Grey Beard" 

 believes he saw October 3, 1881, in case of a child poisoned by whisky ; 

 if however he is "optically deluded," whoever will take the scales from 

 his eyes will receive grateful thanks.

THE MICROSCOPE ON THE DRUGGISTS' COUNTER. 



The following drugs were purchased as fair articles. The 

 mace came from a grocery. 



In a number of powdered opiums a supposed adulteration was 

 found so closely resembling mustard as possibly to be mistaken for 

 it. The source of this vegetable tissue proved to be an excessive 

 impurity of the gum, differing, however, from th^ latter's wrapping 

 leaves. Whether these leaves or this impurity came from the poppy 

 plant remains to be seen upon procuring a specimen of papaver. 

 A small amount of starch was seen in one of the two specimens of 

 gum opium, but in none of the powdered.
