. The anatomical record. Anatomy; Anatomy. 178 G. CARL HUBER in tubiili recti attached to the rete testis. Wax reconstructions made by Curtis confirm the observations made on teased piepara- tions. Repeated teasings have convinced me that in the adult bird no such arrangement of tubules pertains, but that the seminiferous tubules of the bird are arranged in the form of a network, presenting a varying number of anastomoses found at different levels in the gland substance. For this reason the teasing of these tubules is exceedingly difficult in that it is im- possible without breaking or tearing tubules to separate favor- able pieces preparatory to final teasing. All of my teased prepa- rations present an endless net, with broken tubular ends as a Fig. 1 Teased preparation showing a portion of the tubular system of the testis of the bird (Gallus domestica). X 5. In the accompanying figure is presented one of the most suc- cessful preparations obtained. The figure was traced and sketched with the aid of the camera lucida at a magnification of 50 diameters, reduced to a magnification of 5 diameters in the reproduction. The portion of the tubular net reproduced presents in all some forty broken ends, and at least three closed rings. Such closed rings I have found in nearly all of my prepa- I'ations. Their conii)lete separation I'equires great care and patience since uniting tubular poitions are very easily broken. The clearness of the figure, it is thought, obviates the necessity.
