teeth were found in the epithelial and osseous tissues. Both 
incisors and premolars were represented in the dentation, and 
as is very unusual in Dermoid tumors, at least one of the in- 
cisors belonged to the milk dentation. This was indicated 
not only by the size and shape of the tooth, but also by the 
facet that the root had been almost wholly abserbed. Giant 
cells were found in abundance around the root of this tooth. 
All of the teeth were held in place by alveolar processes more 
cr less perfectly developed. Aside from the tissues named, all 
of which belonged to the outer and middle germinal layer, 
there was one piece which somewhat resembled a portion of 
an intestine in gross structure, though the minute structure 
did not bear out this interpretation. 
The origin of Dermoid tumors has not yet been satisfactorily 
explained. So far as this particular one is concerned, it is 
quite possible that it was a twin of the patient which for sume 
reason suffered an early arrest of development, and which sub- 
sequently became enclosed in the body cavity of the patient 
(or twin sister). Here it remained in a quiescent condition 
fcr years until it was stimulated into a sudden growth by 
some change which affected the metabolism of the patient. 
SHALL WE PERMIT THIS? 
There is in preparation by the recognized authority in this 
region, a monograph of local importance, which not to publish 
under the auspices of this Academy will be positively disgrace- 
ful. By the exercise of a little effort and some show of gen- 
erosity, the paltry sum necessary for this purpose can be read- 
Uy obtained. The author, the editor and others are giving 
treely of costly time and labor. Must we let this opportunity 
pass for lack of interest among our membership? As before 
remarked, there is an abundance of valuable scientific work 
being done at our very doors and the Southern California 
Academy of Sciences is compelled to let it go elsewhere for jack 
of means to publish it. It is shameful to let this continue.
