1913] Filippo Bottazzi 3^5 



I have endeavored to corroborate my hypothesis, that the 

 granules are disintegrated fibrillar material, by trying to stain the 

 granules with some pigment which would selectively color the muscle 

 fibrils ; and also by attempting to show that the granules possessed 

 double refractive power. My attempts have been unsuccessful, 

 however, although this was not unexpected, because of the ultra- 

 microscopic dimensions of the granules.
