Abstract

The writers have macroscopically observed the lymphonodi in heads and necks, using 21 cats for materials. In conclusion, it may be well to summarize briefly the results at which the writers have arrived ; 1. The lymphonodi were classified into 10 groups according to position as follows : Lnn. submandibulares med., Lnn. submandibulares lat., Lnn. submandibulares med. caud., Lnn. submandibulares lat. caud., Lnn. parotidici cran., Lnn. parotidici caud., Lnn. retropharyngici, Lnn. cervicales superficiales dors., Lnn. cervicales superficiales vent. and Ln. cervicalis prof. 2. No numerical difference of lymphonodi has been found by individuals, sexes, ages or between the right and left sides. About each group of lymphonodi, however, Lnn. parotidici caud. have shown conspicuous variation in number. 3. Arising from the difference of these existing ratios, the writers' 10 groups of lymphonodi have been divided in 3 groups of constant, nearly constant and inconstant existence. 4. Each of the starting areas of afferent lymphatic vessels has been correlated respectively to each of the writers' grouping of the lymphonodi. 5. The writers have classified lymphonodi into 3 types of Z, T and ZT according to the states of their afferent lymphatic vessels and found that these types appear with different tendency in each group of lymphonodi. 6. In many cases, the writers have found the communication of lymph among lymphonodi by lymphatic vessels and by these styles of communication have divided them into 3 types of A, B and C. These types of communication have been found in writers' groups of lymphonodi, and even between those of another.
