The specific weight of the crystals at 15° C. is: 1,612; the equi- 
valent-volume is therefore: 133,99. The topical parameters are cal- 
culated to: y: wp: w = 5,5537 : 4,5194: 5,3383. 
§ 3. Comparing the axial ratio with the parameters of the three 
isomeric tolwene-sulphonamides themselves, their form-relationship 
becomes very clear, if only the interpretation is made somewhat 
deviating from that given in the literature *). 
Adopting the symbols of the different combination-forms, as given 
by WeriBuLL, we can give the following survey of the modified data:

§ 4. II. p-Toluene-sulpho-methylamide. 
This substance, which has the formula: 
and which melts at 76° (., crystallizes from alcohol in the form of 
very thin, transparent, colourless, rectangular little plates.
