MEMOIR OF CALEB B. ROSE.

London on April 24th, 1839; and it is interesting to note that 
Robert Fitch, of Norwich, was elected a Fellow during the 
following month. 
Concerning the researches connected with his profession, it may 
be mentioned that as early as 1815 Rose communicated to the 
‘ Annals of Philosophy ’ (vol. v. pp. 124 — 428) the results of some 
experiments relating to Hepatitis. 
In 1826 he described a case of transposition of the viscera 
(Loml. Med. and Fliys. Journ. vol. lvi. pp. 345, 346) ; and in 
1831 related “Instances of Monstrous Productions” (Mag. Nat. 
Hist. vol. iv. pp. 403 — 410). His son informs me that “he took 
great interest in the study of Entozoa, particularly those hydatids 
so frequently found in rabbits and sheep ; and devoted much 
time and attention to the subject, making many dissections and 
microscopical examinations. In 1833 he published in the ‘ London 
Medical Gazette’ a paper on the “Vesicular F.utozoa,’’ in which he, 
first 1 believe in this country, correctly described and named 
a hydatid which infests the rabbit. This was the Cysfirrrr us 
tennicolli * , a fuller account of the anatomy and physiology of which 
organism lie communicated in 1818 to the ‘Transactions of the 
Medical and Chirurgical Society’ (vol. xxxi. pp. 215- 238). In 
1832 lie notes that the Asiatic cholera had affected some individuals 
within his district ; and he mentions in particular a case at 
Downham in which he was greatly interested. 
In later years Rose was much occupied in the study of certain 
parasitic borings in scales of fossil fishes. In 1852 he brought 
before the Belfast meeting of the British Association his discovery 
of borings in Chalk lish-scales ; and he suggested the name of 
Talpina squama for the new organism. In 1855 he communicated 
his fuller observations on the subject, together with illustrations, to 
the Microscopical Society. 
There can be no doubt that the cultivation of any branch of 
natural history is valuable to the surgeon and physician, not only 
from a recreative point of view, but also on scientific grounds — 
for the study of nature tends to infuse a more scientific spirit into 
the ordinary work of the surgeon. As his son informs me, “ he 
had always the habit of careful and accurate observation, which 
made him a good practitioner;” and “in several respects he was 
quite in advance of his time.” Thus Rose gained an extensive
