of 48 '44 oz. The longitudinal diameter is 6-90 ; the parietal diameter 

 5-70; the intermastoid arch 15'0j and the horizontal circumference 

 520 m.m., or 20"5 in. The brain capacity of the poet was thus little 

 more than the European mean deduced by Morton from the miscel- 

 laneous examples in his collection. 



Dr. J. C. Gustav Lucae, in' his " Zur Organischen Formenlehre," 

 furnishes views and measurements of two other skulls of men of 

 known intellectual capacity. One of these is Johan Jacob Wilhelm 

 Heinse, the author of " Ardinghello," a work of high character in the 

 elements of aesthetic criticism, though as a romance fit to rank with 

 "Don Juan" in subjective significance and morality. He wrote 

 another romance entitled " Hildegard ;" in addition to numerous, 

 articles and translations of Petronius, Tasso, &c., which won for him 

 the high commendation of Goethe, and the more guarded admiration 

 of Wieland, His skull, as figured by Dr. Lucae, shows the frontal 

 suture still open at the age of 53, at which he died. The internal 

 capacity of the skull is stated as 41 '4 oz., equivalent to 1173 grms., 

 In this, as in other examples hereafter referred to, Dr. Lucae has 

 gauged the capacity of the skull with peas, and gives the weight in 

 "unzen." In the results deduced from them here the unzen are 

 assumed to be Prussian ounces, the lb. of 12 oz. equal to 350'78348 

 grms. Professor Croft has made a series of experiments for me with 

 a view to correct the error necessarily resulting from the fact that 

 peas do not entirely fill the cavity. The results show that 82-5 

 grms. of ordinary sized peas occupy the space of 100 grms. of water. 

 Deducting 10 per cent, for membranes and fluids, the estimated 

 brain- weight of Heinse is 1379 grms. or 48-7 oz. av. The dimensions 

 of the skull are siven thus : 



Fore part . . . 

 Middle part 

 Hind part . 



The other example produced by Dr. Lucae is that of Dr. Christian 

 Heinrich BiLnger, Professor of Anatomy in the University of
