It is very difficult to determine all these points for a 

 single s})ecies, but the effort will lead on into delightful 

 intimacy with tliese beautiful insects. 



I will furnish (if desired) half a dozen named nymphs 

 of typical genera to any one who will undertake to collect 

 arid rear others.- I shall be very willing to determine 

 nymphs or imagoes fur any one, aud to i)oint out for 

 description such as are new. But I especially desire 

 that accurate field observations and notes l)e made on 

 many of our species of which we now known only tlie 

 names, and to such observers I will give all possible 

 aid. — Can. Entomoloy;ist. 



The Myometrium. — Bertelsmann v/rites regarding the 

 microscopic relations of the myometrium in pathological 

 enlargements of the uterus, wdth particular reference to 

 the muscle cells. He has made (Archiv fur (rvnakoiogie. 

 Band L), a careful microscopic study of twenty-two 

 enlarged uteri (three cases of mero-endometritis, t\)ur of 

 carcinoma of the cervix, three multiple interstitial, and 

 five submucous fibroid tumors). He comes to the follow- 

 ing conclusions : Hypertrophy of the muscle-cells of the 

 uterine wall is fre<iuently associated with interstiti.il 

 liljroids. ?Iypertrophy of the muscle-cells always occurs 

 ■ with submucous fll)roids and in almost every instance 

 wiiere the uterine cavity contains an abnormal su])stance 

 ( pyouietra and hematometra). Hyperplastic changes, 

 also increase of the connective tissue and muscle-cells, 

 were found particularly in metitis and in carcinoma 

 and interstitial tibroids. Tnes.- results correspjud with 

 those of Rilschl and Herczel, who experimented on the 

 wall of the stomach and intestines ])y causing arlilicial 

 stenosis and artilicial irritation.
