Helga and Horst Geuer (Am Sonnenhang 39, 53639 Konigswinter, Germany) had their usual excellent selection of specimens from Eifel and Lengenbach, the former including brenkite, calciobetafite, cuspidine, jacobsite, jasmundite, nickenichite, perrierite and srebrodolskite, and Lengenbach being represented by some early material from the Novacki Institute, which was also the source of some excellent specimens of marrite, rathite, seligmannite, trechmannite and imhofite, together with a small number of lengenbachite specimens of typical bladed form.
