 "you had better marry her." 



" The first conclusion to be drawn from my researches is that 

 in no tissue whatever do there exist 'cells' as isolated individuals." 



The animal body is one protoplasmic mass, in which are 

 embedded a relatively small number of isolated protoplasmic corpus- 

 cles and various other non-living substances." (Page 132). 



Thus he calls the migrating corpuscles and the colored and 

 colorless blood corpuscles "non-living substances." 



On page 135 he says that, "In the light of my investigations 

 the cell theory had to be abandoned." Yet this is the only theory 

 advocated to-day by the great majority of biologists. Histologists 

 will be paralyzed to learn that, "on cartilage tissue have mainly 

 rested, for the last forty years, our biological views." (Page 141). 



Our dental readers will learn of structure found in teeth that 

 they never dreamed could exist. 



"Extremely fine thorns traverse in a vertical direction the light 

 space between two neighboring enamel rods, even where a fibre is 

 not visable." (Page 622). 



"' The enamel is traversed by fibres of living matter located in 

 the interstices between the enamel rods." (Page 624). 



On page 797, under the subject of "urine," we are told, "The 

 pus corpuscles are the best material for determining the general 

 constitution of the patient, his chances for recovery, or the proba- 

 ble duration of his life." 



From the above extracts the reader will form some idea of the 

 book and its author. I believe the bioplasson theory of Heitzmann 

 to be the merest nonsense of the most shallow character emenating 

 from an egotistical and eccentric brain. 



i he subject, however, cannot be dismissed with a sneer, but 

 must be judged upon its merits. 



Now I open Dr. Heitzmann's book and with the utmost possi- 

 ble care 1 follow his directions. I examine the tissue thus pre- 

 pared with the various glasses at my command. 1 apply the -^ 

 objective which will stand the tests given on another page of this 

 journal, and yet nothing like a reticulum is seen. Dr. Heitzmann 

 would reply to me as he has toothers, " insufficient eye-training." 

 "It took me fifteen years to see what I can readily see now." 



\ et in flii- face of all this, I unhesitatingly declare that if [can
