its breadth, 23 inches. The greatest diameter of each os innominatum, is 

 12 inches. The left os femoris is 24 inches long, having only one (and that 

 the great) trochanter. The right os femoris is 23 inches long, having 3 tro- 

 chanter processes. Each tibia is 21 inches long. If all the parts bore a due 

 proportion, this man must have been 8 feet high. 



These bones were found near an urn, inscribed Marcus Antoninus, in the 

 place of the Roman camp near St. Albans. 



Microscopical Observations on the Seminal Vessels, Muscular Fibres, and Blood 

 of Whales. By M, Lemvenhoeck, F. R. S, N° 334, p. 438. 



I have formerly said, that the animalcula in semine masculino of a horse, 

 and those of a dog, are of the same size ; at least they appeared so through the 

 microscope. Since that, I have been very desirous to observe the semen mas- 

 culinum of a whale, in order to discover, if it were possible, whether the ani- 

 malcula in those large creatures did not proportionably exceed such as I have 

 discovered in smaller ones. For this purpose I procured from the captain 

 of a Greenland ship a piece of the penis of a whale, viz. of the thickest part 

 of it, where it was joined to the body, in hopes that I might still discover 

 some of the animalcula in the vasa deferentia. Having opened the vas semi- 

 nale as well as I could, for it was very much dried up, and scraped off a little of 

 the matter that was in it with a small knife, I mixed it with a little rain water, 

 to separate the parts from one another: on which I observed in it a great 

 number of long four-sided particles, most of them having 4 right angles, but 

 of different sizes, and many of them were three times as long as they were 

 broad; but I saw none of them so broad as the diameter of a hair, and 

 the smallest was 100 times less, in some few of which I could perceive no 

 thickness. 



All the said particles, or little figures, were as clear as crystal, so that I 

 concluded they were fixed salts ; and the rather, because they were so hard, 



Leicestershire, and was bom in 1688. He was surgeon to St. Thomas's hospital, to Chelsea hospital, 

 and to Q. Caroline, He was a corresponding member of the French Academy of Sciences, a fellow 

 of the R. S. &c. He died of apoplexy in 1752. His principal works are, 1. Anatomy of the 

 Human Body, an elegant compendium, illustrated by engravings j 2. Osteography, or the Anatomy 

 of the Bones, with large folio plates, exhibiting not only the human bones, both in the sound and 

 diseased state, but also skeletons of various animals. In these plates, however, the appearances of 

 many of the smaller bones are rendered indistinct, in consequence of the attention bestowed upon 

 shading and softening j a practice which should always be avoided in scientific engravings, where 

 shape, proportion and exactness of outlines are chiefly desirable. 3. A Treatise on the High Ope- 

 ration for the Stone; a work which procured him a well-merited reputation as a practical surgeon.
