iwhich request he asserts that the material pubUshed over his'own 

 oiame was furnished him in the form of notes by a late colleague 

 •who has unfortunately died since the publication of the bulletin in 

 <juestion. These notes were furnished, it is claimed, with the as- 

 sertion that they were " recent," but that the abstractor had for- 

 gotten their source, but supposed that such things were "common 

 property." 



I desire to offer no opinion as to the probabilities of such an oc- 

 ■currence, and distinctly disavow all intention of publishing any 

 aspersion concerning a fellow worker. My only claim is that the 

 material published in the October bulletin of the Colorado station 

 was originally mine, and that it was utilized without credit either 

 ■to myself or the alleged abstractor of the notes in question. 



Further, that the order in which the statements made occur is 

 identical with the order in which they occur in the pages of my 

 work alluded to, and that, as is demonstrated in the last extract 

 made, even where my own language is not used verbatim without 

 credit, the order followed and the subject matter presented are 

 identical with my own. For instance : in discussing the condi- 

 tions modifying soil temperatures, paragraphs with topic titles 

 were given to " ^^egetation," " Condition of Atmosphere," " Angle 

 ■of Contact," and " Electricity " in exactly the order followed in the 

 Jast extract made. 



Moreover, that frequently tables are given with the identical 

 ■words of introduction used by myself, although so far as 1 know the 

 ■original exists only in German, and the translation and the authority 

 were originally published by myself, though the bulletin alluded 

 to refers to the original in, however, the identical language used 

 ;by myself as translator. 



I desire to make no comments ; indeed, none seem to be re- 

 -quired. I simply desire publication of the actual facts as a simple 

 matter of justice to myself and to the numerous scientific workers 

 ■who must be interested parties. H. E. Stockbridge.

 has been to give a very low armature resistance combined with 

 great strength of field, thus securing high efficiency in a motor of

 size, and Fig. 3 shows a motor adjustably mounted on a base.
