Lambeth had two workhouses at this date -- Princes Road and Renfrew Road -- and Princes Road tended to be used as an infirmary while the new infirmary was being built in Brook Street (opened 1877). That might explain the ambiguity in the newspaper report. Background information here ...
http://www.workhouses.org.uk/Lambeth/#Post-1834Some of the Lambeth poor law records are online (at Ancestry,
unindexed). I found a few references to him, but you may want to look further yourself (if you have access).
Looking at the Creed Register for Princes Road, I found no admission for Samuel Putz between 1869 and 1875, so unless he was admitted
before 1869 he wasn't there for the 1871 census, and he isn't showing there on a search of 1871.
The Princes Road Creed Register shows that Samuel Putz, age 57, a confectioner, was admitted there on 14 Jan 1875, spent 4 months there, and was transferred to the workhouse (presumably Renfrew Road) on 10 May 1875. Three days later (13 May) he was sent back to Princes Road by the medical officer, remained another 4 months, and then returned to Renfrew Road on 30 Sep 1875. There is no further information in these entries.
The Rough Settlement Examinations for 1875 show that he was interviewed in the workhouse on 4 October, to confirm whether he was eligible to continue receiving assistance from Lambeth:
Samuel Putz, 57, born in Amsterdam, Confectioner, rent(ing at)
Lambeth Walk, 4 years
(no further information)
The Lambeth registers for the period October 1875 - August 1877 (when he died) are incomplete. He may have remained all that time in one or other of the Lambeth workhouses or infirmary wings.
The death certificate would clarify which building he died in, but other than it won't necessarily add to what you already know from the newspaper. If you want to order it, the death is indexed as
PULZ, Samuel, aged 61 (Sep Qtr 1877, Lambeth 1d 226).
The newspaper report of the inquest said he had also been in St Bartholomew's Hospital. They have records, which could perhaps be requested from the archivists. Contact details here ...
