    in a series of different vertebrate tissues, concanavalin A binding sites were localized precisely by an alkaline phosphatase-labelled concanavalin A-diazo blue B (Con A-ALP-DBB) method. The results obtained with control staining procedures for the Con A-ALP-DBB method substantiated the usefulness of this staining method. The successful use of Con A-ALP conjugate in the Con A-ALP-DBB staining method is regarded as a starting point for the development of Con A-ALP methods which are better than Con A-peroxidase (PO) methods in the preservation of tissue sections and are applicable to tissue specimens for both light and electron microscopy.

    The author has investigated the arterial distribution of the trigeminal ganglion in the dog by means of the acryl plastic injection method, and additionally the basic structure and topographical relations of the ganglion.
    1. Most of the ganglion was located in the impressio trigemini on the base of the greater wing of the sphenoid bone, and a small, posterolateral part of it extended in the major petrosal nerve canal hiatus of the temporal bone.
    2. Ganglionic branches arose from the following vessels; the petrosal branch, the anastomotic ramus, the anastomotic artery, the middle meningeal artery, the accessory meningeal branch and the internal carotid artery, in order of the frequency. Of them, the first and the second were the main blood supply route, and the middle meningeal assisted it.
    3. Ganglionic branches from various sources ramified into small arterial vessels, by some of which the supraganglionic and infraganglionic retia were formed in the capsule of the ganglion, and the others of which entered the ganglion from the forks between three divisions. Finally they spread into capillary networks, in one mesh of which one or two nervous cells were held.
    In conclusion, the main route of the blood supply of the trigeminal ganglion in the dog was the extracranial blood source and in assistance of the intracranial. Communicating channels between both sources, the internal and external carotid systems, were the anastomotic ramus and artery as well as lots of multisource ganglionic branches.

    In the present work authors studied the morphology of cervical lymphatic system using 26 new-born white rats of both sexes. The studies were performed by injecting China-ink under skin of the angle of mouth and dorsal region of auricle in order to visualize and then proceed the dissection of lymph vessels and nodes under stereoscopic microscope. Morphological descriptions of superficial and deep lymph vessels and lymph nodes were made, recording: a) a dense capillary network of the superficial system that joins in larger branches going to submaxillary lymph nodes, generally by singles on each side; b) those lymph nodes send efferent branches to deep cervical lymph nodes generally single too on each side; c) those lymph nodes give efferent branches which are going to form the jugular lymphatic sac that is going to join to jugulo-subclavian junction; d) the jugular lymphatic sac may receive branches from the plexus which go along with omocervical and external jugular veins and branches coming from the thoracic limb as well as may gather to branches coming from thorax; e) the branches in the most of cases, form plexus and are seldom individualized.

    The acrosome of the grasshopper, Acrida lata Motsuchulsky, consists of an acrosomal cap, two acrosomal arms and a subacrosomal rodlet. The two acrosomal arms 5.0 μm in length and 100 nm in width run along the bilateral sides of maturing spermatid. The subacrosomal rodlet 5.0 μm in length and 220 nm wide is lodged in the electron-lucent acrosomal groove deeply housing the nucleus. When the spermatid juts out into the intercellular space between the nutritive cell and spermatid in an early stage of spermiogenesis, the acrosomal granule is enclosed with the dense acrosomal cap 43-57 nm thick which might originate from the Golgi complex of the nutritive cell. This docking-like phenomenon seems to be similar to the receptor-specific mechanism. On the basis of the results of serial sections, it is concluded that the acrosomal cap of developing spermatids may be a supporting apparatus for the long cone-shaped spermatid, since the cap is connected either with the plasma membrane or with the similar cap of an adjacent spermatid.
